The question doesn't ask for the disconnecting mean. It just ask for what is the NEC listed as the maximum locked-rotor current for the design B, 40 hp induction motor which is a straight look up table from 430.251.What has locked rotor amps to do with sizing of disconnect switch?
430.110 (A) says the disconnecting means to be " not less than 115% of FLA"
Any comments?
