r VOLUME 1 ADMINISTRATIVE PROCEDURES Revision 16 PROCEDURE 3.2.1 Page 21 of 61 MAINTENANCE ORDER PROCESSING Electrical Equipment Qualification u.
If working on items which are included in the Electrical Equipment Qualification (EEQ) program, ensure that the work activity will not invalidate the qualification status of the item.
Equipment and schemes which are EEQ can be identified in Volume 17. Q-List Section 17.2 will have an E code in the N field of each EEQ-Listed equipment number. Q-List Section 17.8 will have an (E) listed for each scheme which contains EEQ items.
For a more detailed description' of the EEQ Program refer to Q-List Section 17.10. For each Maintenance Order which affects an EEQ item or scheme, complete Attachment 9 from Q-List Section 17.10.
When a functionally Equivalent Substitution (FES) is used, the v.
Maintenance Order or Maintenance Package shall contain an Engineering Analysis (EA) worksheet providing written technical justification addressing the adequacy or alteration, and all applicable documents that are required to be updated to reflect the change.

Fuse Control Guidelines To assure specified fuses are used whenever replacement is necessary:
CAUTION:
If a fuse is found in a circuit which does not conform to design documentation i
(P&lDs, vendor files, etc.), a DR shall be written to evaluate the proper corrective action.
1)
Replace the fuse with a like-for-like item.
(Same type, physical size, voltage and current rating.)
2)
If the type, size and rating cannot be determined from the removed fuse; it is then necessary to review plant and vendor drawings, diagrams, sketches and prints for the information.

3)
If the correct /specified. fuse still cannot: be determined,-
consult with the BRP Engineering Department for assistance.
N011: The BRP Coordination Study included walkdown! field verification of electrical 480 VAC circuits'and recording of fuse size nameplate data.
This information is available.from Engineering and should be referred to' for 480 VAC fuse size determinations.
4)
If the need arises to replace a fuse with one that'is not like-for-like, the replacement must_be documented via the Functional Equivalent Substitution process, if applicable, or under the modification process.

Repeat Maintenance
'l Additional maintenance on a component to correct a problem 1
previously considered corrected within the past twelve months is cause for the job planner to initiate a root cause y
)
determination process.
I Repeat maintenance may be either rework (human error)'or recurring (design or application problems). The root cause determination process will insure the overall evaluation of the repeat maintenance is reviewed by' appropriate management..
d Followup correction action (s) will be determined and assigned,-
as necessary, through the Repeat Maintenance Review Board meetings, as described in Maintenance Department Policies.
