If you have a trough with romex circuits going into it and from that trough two nipples going to a main lug panel and in one nipple is all the neutrals and the other are the hots is the ok by code. Will there be too much heat build up.
WOW!...
Think of how much time would be spent to REALLY make that happen.
What happened to the ground? Just cut off where you seperated the hot and neutral?
If the nipples were PVC and a slot were cut between them on both enclosures would this comply with the NEC? I've read about cutting slots for this reason but have yet to see a real world application. Could this be one?
