Our first two weeks in the RV have been full of little projects, some we planned and some which just popped up. This is checking and tightening electrical connections. Our coach has a 30 amp shore power hookup. That is fine in most situations but it means that multiple high loads like both ACs or the washer dryer, can't all be run at the same time. It also means that it's is even more important than usual to be mindful of electrical connections and safety. With lots of country road driving electrical connections can loosen up. A loose connection doesn't conduct electrical current as well as tight one. Without getting too deep into the technical weeds of RV electrics, those connections can get hot and prevent high load devices from running properly.
This is what the inside of our PowerTek Breaker Panel looks like, anyone who has worked on a residential panel at home will recognize the bulk of it. Most of these conductors are solid Romex type wires and they are the ones probably most likely to get loose during driving because the can’t flex the way stranded wire can. Every screw terminal should be checked for snugness periodically and the buss behind the breakers checked, it should be clean and shiny, and carbon build up or scorching.
While on electrical, every RV owner, and especially full timers should own a good Multimeter and know how to use it. I know lots of people like the free ones you get at Harbor Freight, and I’ve used them before, but I don’t trust them for anything important. A midrange meter is a tool worth investing in and will last a long time. This particular Klein meter has a clamp that can read (approximately at least) both AC and DC amps. In an RV this can be very useful for checking current draw on a circuit under different conditions or the amount of charge current flowing to a battery.
Now I must stress that the electrical systems in your RV are one of the things that can kill you if you aren’t careful and know what you are doing. Plumbing leaks and causes a mess but bad wiring can shock you (or a guest or loved one) and start fires. So if you don’t have a good base of skills it is probably best to leave this stuff to a professional.
