Do the two distribution boxes share a common ground
Separate circuits must share a common grounding system, as the entire electrical system is designed around a single, unified grounding network. Electrical. Yes, generally you must unless there is a good reason not to do so. pls share the. Sometimes if I have a 3 or 4-gang plastic nail-on switch box that has a bunch of NM cables, when I'm making up the box rather than using a big blue wire-nut for my grounds I'll separate the grounds into 2 groups and use red/tan wirenuts instead, especially if there's 2 circuits in the box. I would like to do this on a duplex 20A breaker to save space in.
