2.1.4 The installed thermal overload e era are 1 valuated as follows:

The maximum motor full loam ent given in the table is multiplied by 125% and by tM ercent setting of the overicad relay. This value is t p current of the overload heater. The trip current of the h r is then divided by the nameplate full i load current of the to determine the percent protection.

fo11cvs: i a) Using the time-current curve for the overload relay (Ref.'di Shts. 5-7) locate the 15 second point and detemine the current rating multiple for the particular zone of curve selected. Locked rotor current is divided by the current rating multiple to calculate the trip current. Divide trip current by factor of 1.25 to determine the heater selection current. (Ref. 49) b) The heater is selected for the starter size it will be used with, ne heater selecte,d should have minimun current rating equal to or less than the current calculated in 2.2.?a above.

c) ne overload relay trip current (It) is calculated by multiplying heater mininum current (Im) by factor of 1.25.

(Ref. 49) -

d) Determine the tripping time of the heater at 100" Full Load Current (FLC), 200% FLC and Locked Rotor Current by dividing these values by the tripping current. The percent values obtained shall be used to decemine the maxinum and minimum gg trip times from the heater curve operating band and recorded on the calculation worksheet. D e heater tripping zones and time-current curves are given in TVA ce:orandum dated March 2, 1987 (RIMS 322 870302 013). The values obtained will then be compared to the criteria outlined in 0IR-EEE-47031 to s er;fy the acceptability of heater selected.

2.2.3 Acceptability of existing thermal overload henters will ba detemined using the method described in 2.2.2 above and based on i the follouing: I a) Heaters will be se. acted based on an overload relcy setting of 100"..

b) Existing heater uill be reset or replaced as required.

2.2.4 If the Locked Rotor Current /Anps (LRA) is to be detemined f rom the NEC code letter, select the maximum v.tlue from Sec. 3.5 UEC  !

Table 430-7(b) and multiply by the motor ratei horsepover. The l VNA value obtained is divided by the square root of three and the j motor rated voltage to detemine the motor Loched Rotor Curront. -
