I want to hook up two 120 V rectifiers in diffrent enclosures but I want to run one 4 conductor teck cable instead of 2 2conducotors cables and run a nipple between the two.Bring the teck cable to one rectifier and run the other conductors through the nipple to the other rectifier.One person tells me that I have to put the rectifiers on a double pole breaker because they are in the same cable instead of a single pole breaker for each individual rectifier.
