I have (2x) 75 HP elevator motors at 208V., 3 phase. Full load amps = 181, Starting amps = 635.
If I look at the Table 430.250, 75HP at 208V is 211 Amps but here it's given 181 Amps for (2) 75 HP motors. How do I size fused disconnect switch for it? Do I take 181 Amps and multiply that by 2 and then by 140% for continuous rated motor?
