Does the NEC allow (rather prohibit) running two circuits of the same ampacity to multiple loads and connecting the two circuits together at the end of the run?
Example. Pull a 100-amp rated cable to power center A that has two 50-amp (240-volt) shore power receptacles, then loop out of this power center to the adjacent one (B) (configured the same) and then back to the panel. Both cables in the panel will be connected to separate breakers (phasing maintained).
My 1st reaction is no way. Then, I thought about it and did not know the reason why. I don't see how a fault could put more ampacity on the conductor than it was rated for, and the power centers have their own OCD for their outlets.
Thoughts?
