I have a 400 amp service with two 200amp mains on the outside that feed 2 200amp main lug panels in the house.
The feeder coming out of the main panel 4/0 SER cable has to have a romex connector on it, but then I need a 3" nipple for a chase in the wall.
The only way I could figure out how to do it, put the Romex connector inside the panel backwards and then thread a coupling onto it.
Is this legal or how would you protect the wire from abrasion from the panel to inside the wall?
