my panel at my house was a mess, i attached a 6x6 trough to the side of the panel with 2, 2" nipples, i plan on bringing all the circuits, 42 of them into the trough with bx connecters, then splicing new leads of 12 awg to the old runs and bringing them thru the new nipples into the pannel. Question, is this against code,or do you have any other suggestions thanks!!!
