SUMMARY

(Continued) Th3 program was successful in meeting all of the above objectives. The test program was ( designed to demonstrate the acceptability of the as-built raceivay configuration in cecordance with Section 6.1.1.3 of IEEE Standed 384-1981 wbkh allows the use of testing and analysis to justify separation which is less than the standard distance. { Tha test program was performed as specified in lieference 8.2 which is detailed in Paragraph 2.0 of Sections I through IV. Each of the thirty (30) individual tests were [ conducted in the sequence listed below: o Baseline Functional Tests ( o Overcurrent Test o Functional Tests , To enhance the clarity of the test results, this test report groups tests of similar configurations into the sections of the report as listed below. ( o Section I - Configuration Number 1 Tests (60" Vertical Separation between Two Horizontal Trays) o Section II - Configuration Number 2 Tests (1" Vertical Separation between Two Horizontal Trays and 0" Sepwation ( to a Vertical Tray) o Section III - Configuration Number 3 Tests (Various Conduit, Gutter Box and [ Horizontal Tray Configurations) o Section IV - Configuration Numbdr 4 Tests (. (Conduit to Conduit and Conduit to Free Air Configurations) o Section V - Wyle Labo.atories Test Procedure [ Number 46960-1. Six (6) anomalies occurred during this test program. These anomalies are detailed in the ( cppropriate sections of this report and are briefly described below: Notice of , Reference Anomaly No. Date DWption Section { 1 11/29/83 Documents a procedarc.1 change I which changed the fault cable con-nections from series to parallel. This change was made to increase the severity of the overcurrent test by prsventing a phass-to-phase short from limiting fault cable temperature rise. WYLE LABORATORLE14 Huntsville Facill y

SUMMARY

(Continued) Notice of Reference Anomaly No. Date Description Section 2 11/29/83 Documents the failure of Configur- I ation 1 Test 5A due to the ignition of the faulted dropout cable. This test demonstrated that the dropout l I cable requires either additional separation or a thermal barrier to be applied. This test was repeated successfully with a single wrap of 2" Hygrade Thermoflex 1200 fiber-glass flat wrap, 50% overlap, cov-ered by a single layer of 2" 3M No.69 glass tape, 50% overlap. This second test proved that the Hygrade Thermoflex/3M No.69 tape combination is an effective thermal barrier for the dropout cable. 3 12/13/83 Documents a procedural change to II Configuration 2 Tests 1, 2 and 3 which required that a 5/C 20AWG cable be substituted for' the 3/C 4 AWG target cable. This was done to insure that both the 1srgest and smallest cable sizes that could be expected at Limerick Generating Station were evaluated ,during these tests. . . 4 1/06/84 Documents the failure of Configur- III ation 3 Test 6 due to the severe damage to the cables in the cable tray. This test had a 5-inch con-duit, with a faulted Anaconda 750 MCM cable inside it, resting inside a cable tray. This test was an attempt at a worst possible case. However, this configuration does not exist at the Limerick Generating Station. This test was repeated successfully with the 5-inch conduit mounted 1/4 inch underneath the cable tray.

In order to determine what separation [ r4quirements are appropriate, the potential hazard to be protected against must be id:ntified. For electrical raceways in nuclear power plants, the potential hazards are 1) damage due to missiles,2) damage due to pipe break,3) damage due to exposure fires, and 4)

.[.  . damage due to electrical fires in adjacent raceways. At Limerick, the adequacy of the A      separation of raceways for protection against hazards 1) and 2) has been assured through the Limerick Separation Review Program. This program has evaluated and documented the potential effects of mechanical hazards on redundant equipment that is important to safety.

The hazards evaluated included water flooding, steam flooding, jet impingement and mechanical missiles. The adequacy of raceway separation for hazard 3) was evaluated in the safe shutdown analysis documented in the Limerick Fire Protection Evaluation Report (FPER). That review resulted in the addition of raceway fire barriers in certain locations to assure that the plant can be brought to cold shutdown regardless of where an exposure fire xcurs. Hazard 4) is addressed by the separation criteria to be determined and verified by this test program. L WYLE LABORATORIES Huntsville FacHity

5A PURPOSE (Continued) 5.1 Assumptions of Failure Modes (Continued) In order to perform a test program to verify the adequacy of the raceway separation criteria, it was necessary to define the worst case electrical failure that could be postulated to occur Internal to a raceway. Certain assumptions were made regarding the failure mode to be simulated to ensure that ample conservatism would be embodied in the test results. The assumptions used were consistent with those accepted by the Nuclear Regulatory Commission (NRC) for the test program conducted by Philadelphia Electric Company on internal control panel wiring separation as documented in Reference 8.4. That test program made the following assumptions which were also used in the tests and analyses contained in this report:

1. The cable or equipment in the circuit develops a fault that is not cleared due to the failure of the primary overcurrent protective device.

2. The fault current level is just below the long-term trip setpoint of the next higher level overcurrent device.

                                                                                                 )-

3. The impedance of the fault adjusts itself automatically to maintain the fault current magnitude at a constant level as the resistanes of the wire increases due to heating. f

4. There are no other loads on the same circuit which would cause the next higher level overcurrent device to trip.

                                                                                                 ]

J

5. The overloaded wire can maintain the continuous overheated condition without an operator being aware of the condition.

The above assumptions are applicable to tests which simulate the effects of wiring faults which cause sustained overcurrent conditions. Reference 8.4 showed that the heating effects of this type of failure with the above assumptions had the greatest impact on adjacent wires; therefore, this failure mode was chosen as the design basis for the Limerick test program

                                                                                                 ]

! 5.2 Review of Limerick Design In order to determine the test parameters that had to be used to simulate the worst case conditions that could occur at Limerick, it was necessary to review the various sources of power to cables which run in the raceways. These power sources and their associated cables can be categorized as follows: A. Cable Trays and Gutters

1. 480 VAC from load center to motor control centers

2. 480 VAC from motor control centers to 480 volt loads

3. 125/250 VDC from distribution busses to loads -

4. Control and instrumentation (120 VAC and lower) ,

3. 2.3 kV power

4. ' All of the caules shown above for cable tray and gutter.

After review of the design of the above circuits at Limerick, the following conclusions were drawn:

1. There are very few cases where cables larger than #4/0 AWG are run in open cable trays. Cables larger than #4/0 in cable trays fall into categories A.1 and A.3. Because these cables can be subjected to up to 3500 A under the assumptions given in Section 5.1, their failure is expected to have much more severe consequences than the failure of the vast majority of cables, which fall into categories A.2 and A.4. For this reason it was decided not to test cables in trays larger than #4/0. For those cases in the plant where cable larger than #4/0 is run in cable tray, the standard separation requirements given in IEEE Standard d 384-1981 will be met.

[

2. The range of power cable sizes to be tested as potential fault cables in cable trays and gutters was selected from 3/C #10 AWG to 3/C #4/0 AWG. This was based on a review of cable sizes used to feed 480 VAC loads. The worst case

(_ cable size to be used in the test program was selected during the configuration

                 #1 tests.

3. The fault current magnitude was selected as 660 A for cables located in tray and gutter. This value was based on the assumptions listed in Section 5.1. The long time overcurrent trip setting on the load center breakers which feed the motor control centers is 600 A. This breaker would be the second level overcurrent device if the 480 volt motor control center breaker failed to clear a fault. As the load center breakers have solid state overcurrent trip devices which have a tolerance of +10%,~ the 660 A fault current value was selected to be used in the

{ cable tray tests.

f. 4. 1/C 750 MCM cable was chosen as the fault cable size to be used for tests with

( faults internal to conduits. This is the largest size cable used inside areas of the plant containing equipment important to safety. ( 5. The fault current level to be used on the 750 MCM was selected to be 3500 A. This current level was based on the amount of continuous fault current which would be seen on a 480 volt feed from a load center to a motor control center [ given the failure of the load center breaker to operate.

6. The parameters of cable size and fault current selected above encompass the conditions which can result from failures in categories B.1, 2 and 3 because of

[' the high speed relaying on the system and the high fault current availability. These features will cause either backup relaying operation or rapid cable failure, thereby preventing long term heat generation. Huntsville FacHity

Page No. xviii Test Report No. 46960-3 h 6,0 CONCLUSIONS (Continued) 6.1 Configuration Number 1 Conclusions (Continued) These results generated the following conclusions:

1. A sixty (60) inch vertical separation between two (2) horizontal ladder rung cable trays was demonstrated to be adequate physical separation during the worst case electrical fault conditions in any cable Size 4/0 AWG or smaller in the lower cable tray.

2. It was demonstrated that application of the worst case long-term overload current of 660 amperes to Rockbestos cable Sizes 4/0 AWG,2/0 AWG, 6 AWG and 10 AWG does not result in ignition of the cables insulation system when the faulted cable lies in the horizontal plane. The fact that ignition does not occur is significant because it indicates that reduced vertical separation distances are acceptable.

3. It was demonstrated that the cable tray walls serve as an effective thermal barrier when the worst case electrical fault occurs to a cable on one side of the cable tray

(. wall with Size 7/C 14 AWG dropogt cable in contact with the other side of the cable tray wall. For gTest 4B, a 1090.9 F temperature on the faulted 3/C 2/0 AWG was reduced to 203 F on the 7/C 14 AWG cable in contact with the other side of the cable tray wall. [

4. Tests 1 through 4B revealed that the worst case cable (WCC), with the 660 amperes fault current was the 3/C 2/0 AWG cable. In addition, Test 4B demonstrated that this L- cable achieves its highest jacket temperatures when faulted as the top layer of cable in the cable tray. As a result, this cable size was used as the fault cable for the remaining tests where the fault cable was located in a tray or gutter box.

5. It was demonstrated that a single layer,50% overlap, of 2" Hygrade Thermoflex 1200 flat wrap covered by a single layer, 50% overlap, of 3M Number 69 glass tape is an effective thermal barrier for an internally-generated electrical fault on the Limerick Generating Station worst case cable. The Hygrade Thermoflex and 3M No. 69 tapes demo trated the ocapability to reduce a dropout fault cable jacket temperature of 1188.6 to 145.2 F on the jacket of a 3/C 4/0 AWG cable in cable tray. In addition,

[- the Hygrade Thermoflex and 3M No. 69 tapes demonstrated the capability to preclude ignition of the insulation system. L [ [ ! -._m. Huntsville Facility

S (Continued) ! 6.3 Co @. tion Number 3 Conclusions (Continued) These results generated the following conclusions:

1. It was demonstrated that a configuration where a 2" rigid steel conduit, a 6"x6" gutter box and a ladder rung cable tray are in contact with each other, with the conduit and gutter box mounted below the tray, is adequate physical separation when the worst case electrical fault occurs in either the conduit or gutter box.

( 2. It was demonstrated that a configuration with a 2" rigid steel conduit, a 6"x6" gutter box and a bare dropout cable are in contact with each other is adequate physical separation when the worst case electrical fault occurs in either the conduit or the dropout cable. In addition, these tests demonstrated that a 2" rigid steel conduit is { effective in dissipating the heat generated from an internally or externally generated electrical fault to a 3/C 2/0 AWG cable, such that a cable external or internal to the conduit, respectively, is not significantly damaged.

3. It was demonstrated that a Rockbestos 3/C 2/0 AWG cable, inside a 2" rigid steel conduit or 6"x6" gutter box, does not ignite when exposed to a 660 ampere current until the cable open circuits.

4. It was demonstrated that a configuration where a 2" rigid steel conduit and a 6"x6" gutter box are mounted directly above and within one (1) inch of an electrically faulted worst case cable is adequate physical separation.

5. It was demonstrated that one (1) inch vertical separation between a 5" rigid steel

[ conduit and a ladder rung cable tray is adequate physical separation when a 750 MCM cable is subjected to the worst case electrical fault inside the conduit. The 5" rigid steel conduit reached temperatures of approximately 800 F and therefore this conduit cannot be relied upon as a thermal barrier with bare cables directly in contact with it. The conduit did, however, demonstrate adequate protection from propagation of fires when the faulted cable ignites inside the conduit. T [ [ [ [ WYLE LABORATORIES Huntsville FacHity

These results generated the following conclusions:

1. A one (1) inch vertical separation between a 5" rigid steel conduit and a 2" rigid steel conduit was demonstrated to be adequate physical separation when a 750 MCM cable was subjected to the worst case electrical fault inside the 5" rigid steel conduit.

2. A one (1) inch horizontal separation between a 5" rigid steel conduit and a S/C 20 AWG dropout cable was demonstrated to be adequate physical separation when a 750 MCM cable was subjected to the worst case electrical fault inside the conduit.

3.

Athough the outer jacket of the 3/C 6 AWG cable was severely damaged, this cable did: (1) maintain -

sufficient integrity to conduct rated current at 480 VAC before, during and after the 750 MCM cable was faulted until an open circuit occurred, 2) maintain sufficient insulation integrity to hold 500 VDC from phase-to-phase agd from each phase to the ! conduit with insulation resistances greater than 1.6 x 10 ohms, and 3) maintain sufficient insulation integrity to hold 2200 VAC from phase-to-phase and from each - phase to the conduit without evidence of insulation breakdown or flashover.

 }

Energized non-fault specimens in the " target" raceway shall conduct 100% rated current at 480 VAC (120 VAC for instrument cables) throughout the overcurrent test. 2.0 PROCEDURES 2.1 Test SpecimenIdentification An inspection was performed upon receipt of the test specimen components at Wyle Laboratories. This inspection was to assure that the test specimens were as described in Paragraph 7.0 of the Introduction section. Applicable manufacturer, wire size, number of conductors and trade name were verified and recorded. The test specimens were labeled as necessary to facilitate identification throughout the test program. 2.2 Test Specimen Preparation The test setup for the nine (9) Configuration 1 tests was identical except as noted in the following paragraphs.

 ;       The test specimens were placed in the cable tray assembly as shown in Figure I-1 or I-2 of Appendix II of this section. This apparatus was assembled to the indicated dimensions by Wyle technicians using materials supplied by PECO. The following guidelines were observed with regard to the materials and construction of the cable tray assembly:

1. The cable trays were ladder rung trays 72" by 24" by 4" from PECO stock.

2. The cable trays were supported with unistrut seismic hangers and were mounted such that the bottom of the upper cable tray was 60" above the top lip of the lower cable tray.

3. The upper cable tray was filled full to the top of the tray wall using an assortment of six-foot unpowered power and instrumentation cables from PECO stock (see table below).

4. The lower cable tray was filled full to the EUp of the tray wall using an assortment of six-foot unpowered power and inarumentation cables from PECO stock as listed below:

UPPER AND LOWER TRAY UNPOWERED FILL CONTENTS Cable Size No. Conductors 4/0 AWG 3 2/0 AWG 3 2AWG 3 4AWG 3 6AWG 3 8AWG 5 10 AWG 3 14 AWG 7 16 AWG [ 2 L 20 AWG 5 20 AWG 7 -

5. The faulted cable for Tests 1 through 4B was located in the lower cable tray at "

the extreme right hand edge. The faulted cable was submerged under a layer of passive fill cable for Tests 1 through 4A. For Test 4B the faulted cable was the top cable at the right hand edge of the tray. The ends of the faulted cable from the copper bus bar to approximately the edge of the cable tray were wrapped with a single layer, 50% overlap, of Haveg Siltemp Wide Tape No. 65 covered by a single layer, 50% overlap of 3M No. 69 glass tape. This wrapping was done to insure that any ignition of the fault cable's insulation system was contained to the cable tray test area.

6. The faulted cable for Tests 5, 5A and SB was a dropout cable which exited the upper tray and dropped vertically past the lower tray. This cable was wrapped with a single layer,50% overlap of Haveg Siltemp Wide Tape No. 65 covered by a single layer of 3M No. 69 Glass Tape from its termination at the copper bus bar until approximately 12 inches from the cable tray test area. During Test 5A the faulted dropout cable ignited and this test was conducted a second time (reference Notice of Anomaly No. 2 in Appendix 1 of this section). During this ,

test, the dropout cable was wrapped from the point where the cable left the I rungs of the upper tray until it was 12 inches below the lower tray with a single layer, 50% overlap, of 2" Hygrade Thermoflex 1200 Flat Wrap covered by a single layer, 50% overlap of 3M No. 69 Glass Tape. This additional wrapping was done to: 1) evaluate the thermal barrier capability of the wrapping, and 2) ] attempt to preclude ignition of the fault cable's insulation system. 1 WYLE LABORATORIES Huntsville Facility I

7. Energized nonfaulted cables, referred to as " target" cables in this report, were utilized as described below. For Tests 1 through 4B, three (3) target cables were p

installed in the upper tray directly above the fault cable in the lower tray. Two (2) of these cables, a 3/C Size 4 AWG and a 5/C Size 20 AWG cable, traveled the entire length of the upper tray. The third target cable exited the upper tray at approximately one-half of the tray length and dropped vertically past the lower tray. This cable was tie wrapped such that it was in contact with the lower tray. For Tests 5,5A and 5B, there were two (2) target cables in the lower tray at the edge where the dropout faulted cable passed. These target cables were energized 3/C Size 4 AWG and 5/C Size 20 AWG cables.

8. Photographs were taken of each test setup prior to and at the completion of the overcurrent test. These photographs are presented in Appendices II through XI of this section.

2. All power and instrumentation leads were connected per Figures 11,12 or 13 of Section V.

For all performances of this test, the measured values were compared to the acceptance criterion, Paragraph 1.1.2, i.e., there shall be no breakdown or flashover. The high potential test set that was utilized goes into a current limit mode of operation should leakage currents exceed 5 milliamperes. At this point, the test set reduces the applied voltage. It was therefore designated that breakdown or flashover occurred when the test set could not maintain an applied voltge of 2200 VAC. 2.5 Overcurrent Test The overcurrent test procedure was identical for each of the nine (9) tests with the exception of the size of the faulted cable and its location. Therefore, this test procedure is generalized to be applicable for each of these tests. The overcurrent testing was performed j as described below: WYLE LABORATORIES Huntsville Facility

30. Steps 1 through 21, 27 and 28 were repeated with a 3/C Size 2/0 AWG dropout cable as the fault cable (Test SA).

31. Steps 1 through 21, 27 and 28 were repeated with a 3/C Size 2/0 AWG dropout cable as the fault cable. This cable was wrapped as described in Paragraph 2.2, Step 6 (Test 5B).

216 Post-Overcurrent Test Functional Tests At the completion of each overcurrent test, the functional tests of Paragraph 2.4 were r:peated. 3.0 RESULTS Tests 1 through 4 did not result in a clear defintion of the worst case cable. Test 1, with the 3/C 4/0 AWG fault cable, did not reach extremely high temperatures (4880F maximum) and Tests 2, 3 and 4 with 3/C 2 AWG, 3/C 6 AWG, and 3/C 10 AWG, respectively, fault cables ( were of short duration. Thus, two additional tests were performed using 3/C 2/0 AWG fault cables. These tests yielded much higher temperatures (10910F maximum) and were of approximately 2 hours in length. It was therefore concluded that the worst case cable at the Limerick Generating Station for a sustained 660 ampere electrical fault was the 3/C Size ( 2/0 AWG cable. In addition, Test 4B demonstrated that higher temperatures were achieved ' when this cable was the top cable in the tray vice a submerged cable, as was utilized in Tests 1 through 4B. Two (2) anomalies occurred during this phase of the test program. The first anomaly dealt with the shorting of the fault cable conductors during Test 5. At the 29-minute point during this test, the conductors shorted together and the jacket temperatures exhibited a rapid decrease which lessened the severity of this test. The short circuit occurred as the fault cable exited the upper cable tray and was caused by the weight of the cable pulling the ( conductors together as the insulation melted. The test procedure was modified by Notice of Anomaly Number 1 to connect the fault cable ends in parallel to preclude future short circuits from affecting test results. In order to accommodate the parallel terminations the required rated and 660 ampere currents were increased by a factor of 3. This test was repeated with the parallel connected terminations. At the 29-minute point during the retest of Test 5 (designated Test 5A), the insulation system on the 3/C 2/0 AWG dropout cable ignited. The ignition occurred approximately five (5) minutes after a hole formed in the outer jacket. This hole occurred at the point where

  ~

the dropout cable exited the upper tray and was supported by the cable tray siderail. The [ fire burned for seven (7) minutes and burned down the cable until all available insulation was consumed. As the fire burned down between the two cable trays, a two (2) foot piece of burning insulation fell into the lower and smoldered for the remainder of the test as it [- burned through cables in this tray. The target cables were destroyed by this smoldering fire. 4 Notice of Anomaly Number 2 documents this fire and the retest conducted where the 3/C WYLE LABORATORIES Huntsville Facmty -[

A peak temperature of 563.90F was recorded on the jackets of the cables adjacent to the fault cable in the lower tray. At the 6-minute point during this test a hole popped in the outer jacket of the fault cable and extremely heavy smoke exited the cable at this point. At the completion of this test, the entire jacket had carbonized and was very brittle. The insulation fell off the cable as it was removed from the cable tray area. The jacket to the cables adjacent to the fault cable changed color to a dark gray color and were visibly scorched.

The 660 ampere fault current was applied until the cable open circuited at the 62.45-second point in this test. A peak temperature of 211.70F was recorded on the jackets of the cables adjacent to the fault cable in the lower tray. At the .] ! 30-second point during this test a loud pop occurred as the gases internal to the outer jacket . I built sufficient pressure to rupture the jacket.

3.5 Results of Test No. 4A Configuration 1, Test 4A with a 3/C Size 2/0 AWG fault cable, in the lower tray, was I conducted per Paragraph 2.0 of this section. This test was outside the original scope of work. It was performed to evaluate whether or not the 3/C Size 2/0 AWG cable would yield higher temperatures than Test 1 and result in a test of longer duration than Tests 2 through

4. The 660 ampere fault current was applied for 6826.23 seconds (113.8 minutes) and was terminated when the maximum temperature had stabilized for approximatley 50 minutes. A peak temperature of 655.30F was recorded on the jacket of the cables adjacent to the fault cable in the lower tray. The jacket to the fault cable was intact at the end of the test, although it was very brittle and had carbonized. The individual conductor's insulation and the filler material on the cables adjacent to the faulted cable had several areas where charring had occurred. Based on the results of this test, it was concluded that the worst case cable at the Limerick Generating Station for the 660 ampere electrical fault was the 3/C Size 2/0 AWG cable.

3.8 Results of Test No. 4B Configuration 1, Test 4B with a 3/C Size 2/0 AWG fault cable, in the lower tray, was conducted per Paragraph 2.0 of this section with the exception that thermocouple channels 1 through 6 were mounted directly to the fault cable jacket vice the jacket of cables adjacent ) to the fault cable. This change was made to yield better data on the fault cable temperatures. This test was also outside the original scope of work and was performed to evaluate whether or not higher temperatures were recorded when the fault cable was on the top layer in a cable tray. Tests 1 through 4A had previously shown that ignition of the } faulted cable's insulation did not occur with the fault cable horizontal and submerged under other cables. This test proved that ignition is also not likely to occur when the faulted cable is on the top layer with more oxygen available to support combustion. The 660 ampere fault current was applied for 7355.24 seconds (122.6 minutes) and was terminated after fault cable temperatures had stabilized and decreased approximately 2600F. A peak temperature of 1090.90F was recorded on the fault cable jacket. The jacket to the fault cable remained intact throughout this test with several cracks forming as the jacket carbonized. Very heavy smoke exited the cable at both ends of the cable and through a crack which occurred approximately where the dropout cable passed by the lower tray. j The individual conductor's insulation and the filler material were completely destroyed. The outer jacket on the cables adjacent to the faulted cable had several areas where charring ] had occurred. This test showed that the worst location of the faulted cable, from the J standpoint of temperatures observed, was in the top layer of cable in the tray. WYLE LABORATOMES HuntsvHle Facility

3.7 Results of Test No. 5 lI Configuration 1, Test 5 with a 3/C Size 2/0 AWG fault cable, dropping out of the upper tray, was conducted per Paragraph 2.0 of this section. The 660 ampere fault current was applied for 2941.89 seconds (49.0 minutes) and was terminated after fault cable temperatures had g decreased approximately 1600F over a period of 22 minutes. The fault cable temperatures

 ]   had shown a steady increase of approximately 9 degrees F per minute until the conductors on the fault cable shorted together after 29 minutes of the 660 ampere fault current. At this point, the temperatures began to steadily decrease. The short circuit occurred due to the weight of the seven-foot vertical section which pulled the conductors together as the insulation system melted. When the short circuit occurred, the series terminations permitted a portion of at least two of the conductors to be bypassed. Thus, less heat was developed, due to less cable carrying current, and an additional heat sink formed inside the I   cable. The peak temperature recorded on the fault cable, prior to the short circuit, was 396.90F. At the 26-minute point, with fault current applied, the outer jacket burst (see the hole in Photograph I-39 of Appendix IX) and extremely heavy smoke occurred (see Photograph I-38). In addition, molten insulation rained out of this hole in the outer jacket.

However, at the completion of this test, the insulation was still pliable in most areas of the faulted cable. WYLE LABORATORIES Huntsville Facility

The temperatures on the jacket to the 3/C Size 4 AWG cable (the cable in contact with the opposite side of the side rail from the fault cable) showed a smallincrease from 58.90F to 90.10F. The lower cable tray sideraillips also exhibited only a small increase in temperature from 49.50F to 78.30F.

3.8 Results of Test No. 5A Configuration 1, Test 5A with a 3/C Size 2/0 AWG fault cable, dropping out of the upper tray, was conducted per Paragraph 2.0 of this section. The terminations to the faulted cable were made in parallel vice scMes for this test and for all subsequent tests using the 2/0 AWG cable (reference Notice of Anomaly Number 1 in Appendix I). This was done to preclude short circuits, such as those that occurred during Test 5, from decreasing the severity of subsequent testing. The 660 ampere fault current was applied for 3089.76 seconds (51.5 minutes) and was terminated due to declining temperature readings. At the 23-minute point with the 660 ampere current applied the outer jacket on the fault cable ruptured at the point where this cable left the upper horizontal tray. Prior to the rupturing of the outer jacket, the cable diameter had swelled to approximately three (3) times its normal diameter due to the pressure of the gases inside the jacket. After the jacket ruptured, molten insulation rained out of the hole at a steady rate. l

This insulation fire burned down the cable until it had consumed all available insulation. Very intense gray and black smoke exited the cable and completely filled the 100,000 cubic foot test chamber. As this insulation fire burned down between the two horizontal trays a piece of burning insulation fell into the lower tray. This insulation fire smoldered inside the lower tray and burned through the insulation system on the 3/C Size 4 AWG and 5/C Size 20 AWG target cables. The bare conductors were visible on both of the target cables as well as on several of the passive cables when this test was completed (see Photographs I-44 and I-45 in Appendix X).

3,9 Results of Test No. SB Configuration 1, Test 5B with a wrapped 3/C Size 2/0 AWG fault cable, dropping out of the upper tray, was conducted per Paragraph 2.0 of this section. The fault cable was wrapped with a single layer, 50% overlap, of 2" Hygrade Thermoflex 1200 fiberglass flat wrap covered with a single layer, 50% overlap, of 2" 3M No. 69 Glass Tape. This wrapping started as the fault cable left the rungs of the upper tray and continued to a point 12 inches below the lower cable tray. The remainder of the fault cable, with the exception of the 18-inch portion in the upper cable tray, was wrapped per Paragraph 2.2, Step 5. This additional test was conducted to determine if the Thermoflex/3M No. 69 tape combination could preclude the insulation fires that occurred during Test 5A. The wrapping of the fault cable was successful in precluding ignition of the insulation system. WYLE LABORATORIES Huntsville Facility

Paga No. I-20 Test Report No. 46960-3 3.0 RESULTS (Continued) 3.9 Results of Test No. 5B (Continued) The 660 ampere fault current was applied until the 3/C Size 2/0 AWG cable open circuited after 4280.05 seconds (69.7 minutes). A peak temperature of 1188.60F was recorded on the thermocouples mounted on the jacket and underneath the wrapping on the fault cable. ] Extremely heavy smoke occurred during this test which again filled the 100,000 cubic foot test chamber. The fault cable's outer jacket ruptured at the end of the Thermoflex/3M No. ] 69 wrapping and molten insulation dripped out of the upper cable tray for approximatley 10 1 minutes (see Photographs 1-51 and I-52 in Appendix XI). The Thermoflex/3M No. 69 wrapping remained intact along the entire cable length. The wrapping material did change 3 color as it absorbed some of the molten insulation. In addition, the additional weight of the J cable resulted in the fault cable moving during the test to where the cable was supported by the test setup unistrut hangers. However, the fault cable did remain in contact with the

 -lower cable tray siderall.
                                                                                                ]

The ability of the 3/C 4 AWG and 5/C Size 20 AWG target cables to conduct rated current and 480 VAC (4 AWG) or 120 VAC (20 AWG) was not impaired. There was no evidence of discoloration of the jackets to these cables. The molten insulation readily peeled off these } cables and resulted in no noticeable damage. The highest temperature recorded on the target cables as 195.10F while the highest temperature on the lower cable tray siderails was 1 125.20F. The target cables successfully met the acceptance criteria of Paragraph 1.0 when j subjected to the Post-Overcurrent Test Functional Tests of Paragraph 2.6. Appendix XI contains the following data from this test:

DESCRIPTION OF AN0MALY: At the 29-minute point during Test 5A, the insulation on the 2/0 AWG dropout cable ignited. This insulation fire burned the entire length of this cable and a 2-foot section of insulation fell into the lower tray and smoldered. The 5/C 20 AWG and 3/C 4 AWG " target" cable conductors were visible on these cables. Since the conductors were visible, the post-test insulation and high potential readings were not taken. 1 VERIFICATION: PROJECT ENGINEER: // TEST WITNESS: PROJECT MANAGE [ .
