Per NEC 110.14(C)(1)(a)(4), for motors with design letters B, C or D, use terminal temperature of 75C. Per NEC 110.14(C)(1)(a), if the terminals are not rated and the amp load is 100 amps or less, a terminal rating of 60C is to be used.Multiply by correction factors to determine the design amp load on the conductor.Adjustment factor for a single motor, correction factor 1.25De-rating factor for ambient temperature, use Table NEC 310.15(B)(2)(a); ambient temps higher than 86F will have a de-rating factor of less than 1. De-rating factor for more than three current-carrying conductors in a wiring bundle, use Table 310.15(B)(3)(a).Determine the insulation type for the highest terminal temperature rating using Table NEC 310.15(B)(16Determine conductor size AWG from the lowest terminal temperature rating using Table NEC 310.15(B)(16). Use the row that shows an amp load the same or higher than the calculated design amp load. Note the restrictions in the table on 14, 12 and 10 AWG conductors; if the restricted ampacity value is smaller than the calculated design amp load, increase to the next larger wire size and verify that its ampacity is larger than the calculated design amp load.Sizing of fuses and breakers for short-circuit and ground-fault protection:Determine FLC from nameplate hp, nameplate voltage and Table 430.248 for single-phase motors or Table 430.250 for 3-phase motors.Determine the type of motor from the motor nameplate (Design B, C or D, Squirrel Cage, Single Phase, etc.)Determine the maximum amp rating of the fuse by multiplying the % of FLC value in Table 430.52 for the motor type and fuse type you’re using by the calculated FLC value. Compare this amp value with the standard amp ratings in NEC 240.6; if the calculated amp value is not a standard size, increase to the next larger standard fuse size. If the fuse size is not sufficient for the starting current of the motor, determine the maximum % of FLC value. For Design B motors, use the following maximum values: non-time-delay fuse, 400%, dual-element fuse, 225%, inverse-time breaker, 400%, instantaneous-trip breaker 1100%. If this calculated maximum amp value is not a standard size, decrease to the next smaller standard fuse size.Sizing of overcurrent protection (OCPD):Determine FLA and SF from motor nameplate. Calculate the maximum allowable amp load for the fuse / breaker. For motors with SF 1.15 or higher, multiply FLA by 140%. For motors with SF less than 1.15, multiply FLA by 130%. Compare this amp value with the standard amp ratings in NEC 240.6; if the calculated amp value is not a standard size, decrease to the next smaller standard fuse size.If a mag-starter is required, use NEMA tables on slide 147 to determine NEMA starter size.Sizing of ground:Determine the ground wire size using amp rating of the maximum standard fuse / breaker and Table 250.122. If the fuse / breaker size falls between the values on the table, round up to the next larger size. If this conductor size is larger than the conductors to the equipment, it is permissible to use the conductor size supplying the equipment per NEC 250.122.Sizing of conduit:Determine minimum EMT size from Table C.1(A), calculated conductor size, insulation type and total number of wires (conductors plus ground). Determine minimum LFMC size from Table C.7(A), calculated conductor size, insulation type and total number of wires (conductors plus ground).Sizing of disconnect rating:Determine FLC from nameplate hp, nameplate voltage and Table 430.248 for single-phase motors or Table 430.250 for 3-phase motors.Calculate minimum disconnect amps. Per NEC 430.110, the disconnecting means for motor circuits rated 1000 volts, nominal, or less shall have an ampere rating not less than 115 percent of the full-load current rating of the motor. If the calculated amp value is not a standard size, round up to the next whole number. left-91884500Abbreviated Tables for 430 Motors Course-887104-87345600Quiz 5 – Nameplate InfoThe motor name plate data must include the manufacturer’s ______.namename and addressname, address and website name, address, website and emailname, address, website, email and phone numberA motor is rated to run at 230 volts.
