three phase system in conduit
three phase system in conduit
(OP)
I need information on installing a 3 phase, 4 wire system in rigid conduit from the transformer secondary to a secondary bus. Specifically, is there an explanation out there regarding placing conductors for each phase and the neutral in conduits. More specifically, the pairing should be A-B-C-N in each conduit, not A-A-A-N, B-B-B-N, C-C-C-N in the conduits because of the induced neutral current in the second configuration?

If all the conduit is non-metallic, this is not an issue.
Try searching this form or Google. Should be plenty of information out there.
BTW, this has nothing specifically to do with the neutral. The same problem exists even without a neutral.

After correcting to A-B-C-N A-B-C-N everything cooled down and there have been no further issues.
