When running motor circuits in conduit, where the breaker size is 250% of the FLA, is there an exception to the rule of sizing the equipment grounding conductor, according to the rating of the OCD in the circuit? For example I have a machine with a total amperage of 39.8 amps X 250% = 99.5 amps which would put me at a 100 amp. breaker. Is the ground wire size for the conduit still a # 8 or am I missing an exception somewhere when dealing with motor circuits.. I have other smaller motor circuit conductors in the conduit also, but this is the largest. Thanks, Steve
