Piling on to this because the message is worth it: Color schedule of wiring may be different in an RV from a vehicle and from 120V residential wiring.
This is one instance where someone waving a sheepskin and proclaiming superior knowledge is incorrect. Always, check polarity with a meter for continuity to frame ground before connecting wires to the battery. If it's confusing, get help and mark wires so future battery connecting isn't a mystery.
Me too. As another EE the worst thing you can do is suggest something is always a certain way. It’s a sure fire way to be wrong. Electricity doesn’t care what color the insulation around the wire is, people do. Those people follow all kinds of conflicting conventions and sometimes none at all when making those choices.
As mentioned, 120V uses black for hot and white for neutral contrary to DC where black is usually ground. Since RVs have both systems they tend to have a mix of “standards”.
