  • 50A In Camper Monitor

    Been working on this plan in my head for a while, especially after a connection issue caused me to loose 1 leg of the 50A service. NOTE THE GAUGES NEED TO BE GLUED IN PLACE, THEY ARE SIMPLY STUCK INTO THE HOLES.

    I remember a conversation a while back where the amp meter was giving an accurate measurement of power usage at 1 campground, but not another, which also added to the idea.

    Ordered 3 inexpensive volt meters from amazon. https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1 good voltage swing so should not be an issue.

    Green and Yellow measure line to neutral, red measures Line to Line. If red does not display, that would mean the 2 lines are the same. If either the Green or Yellow is not at reading then there is an issue with one of the feeds.

    Hi Joseph,

    You just added a project to my list !
    I had an idea to do something like this, but not nearly as easy as three voltmeters that fit into round holes . . . very clever execution!

        Very clever. How far did you have to go to get the 120/240 volt connection point and what gauge wire to devices? I saw in the Amazon ad, the same displays are available in square shape, same price too.

          Very cool. Now my mind is thinking of a 50 amp plug with these three meters attached to it so one could plug it into the shore power post to check it before landing the RV into the site, I guess the meter I carry would do the job as well but would not be near as cool.

            Alternatively, install a Progressive Industries surge protector/management system and/or a Victron Inverter and get the same info + a lot more including amps drawn on each leg and the frequency on each leg.

              I have a Surge/EMS out at the post that can tell me this same information, but it can only see "upstream" . . . and the question becomes, is everything correct "downstream" through the cord and connectors? Several years back, we worked through a situation (Paul & Deb) where the EMS at the post indicated that everything was OK but a lost neutral between EMS and trailer cause various appliances to see high voltage and fail. Joseph's idea will tell me if the power is correct right at the RV breaker panel.

                Cate&Rob I dropped a hot leg at the wall connector in a campground. After pulling the fireplace and crawling around under the slide, it occurred to me that everything on one leg of the power panel was not powered. That's when I figured out it was the 90 dogbone had a bad connection. Never had the same issue again, and now I immediately know what's wrong. Plus I can watch voltage swing between the legs.

                    My beloved dogbone is retired, same issue, poor connection on one leg. And then the transfer switch dropped a leg when we came off generator and went back to shore power. Once you have been through the dropped leg routine a couple of times you learn to recognize it pretty quickly. But your little dohickeys would make it a lot easier to observe and a lot easier to see leg voltage than walking outside to look at the EMS on the post.

                    Good job, thanks for sharing.
