I don't worry about my rv power cord length, meters, test probes or what I'm running. With a dedicated 30 amp breaker and outlet, I plug my Lexi in, and leave it 24/7. I run whatever I want, ac, micro, anything. Even take my compressor and run it off the outside outlet on the rig. Bottom line is simply to run 30 amp service. Thats the safest way You don't have to worry about extention cords or tripping a breaker in your garage when you have to use the outlets. Don't have to worry about cords or adapters getting hot. Don't have to worry about what you can or can't turn on.
Mi Lexi has been plugged in, when we're not on the road, for almost a year now, and I've not had one problem.
Again, for the cost of all your heavy extension cords and conversion plugs and testers, you can install a 30 amp line, for less than 100 bucks, and not have to worry.
