50 amp breaker for rv9/12/2023 ![]() ![]() I recently finished the barn, which has it’s own 50 amp sub-panel and a dedicated 30-amp non-GFI outlet for the coach. Yea I know, now I’m in violation for having an outdoor outlet on a non GFI circuit. It’s also a fair bet that if you have 50-amp service, you’ll have two 30-amp sub-panels or breaker panels on the inside. In desperation, I replaced the GFCI breaker on that circuit with a standard 20 amp breaker, which solved the problem. A 50-amp socket has four prongs–two hot wires, a neutral, and a ground wire. A 30-amp socket has two wires (hot and neutral) plus a ground wire (green wire). ![]() Which one does your RV have, 30 or 50-amp service? Besides just looking at the side of the cord, the RV plug will look different. How? By having bigger pipes! A 50-amp circuit will have significantly thicker wires, which can carry more electricity–just like bigger pipes can carry more water. So a 50-amp system can supply more than a 30-amp system can. You can think of electricity as water flowing through the plumbing in your home. Fuses, circuit breakers, sockets, and wires must all be sized to deliver the right amount of power safely. In other words, it’s not just the cord but the entire system. And the outlet and wiring inside your motorhome need to be sized correctly. The RV outlet you plug into at your house or RV park must also connect to a wire that is the right size. Since all of your RV’s power comes through one cord, that cord must be big enough to power everything.Īnd, of course, it isn’t just the cord. For example, most motorhomes and campers in the US are either 12 or 24-volt DC systems and 110-volt AC systems.Īmps are a measurement of how much electricity is flowing through the line. Or, you can make AC from DC if you install an inverter in your rig.Įach system is also voltage specific. But, you can make DC power from AC with one of the best power converter panels. You can’t plug an AC appliance into DC power, and you can’t plug a DC one into AC power. The two types of electricity are not compatible. Big appliances, like your air conditioner, run off of AC power. AC is the type of electricity that traditional brick-and-mortar homes run off of. The AC (Alternating Current) system is the one that gets its power through the shore power cord when you are plugged in. This breaker is thermal-magnetic and accepts 8-6 AWG Cu or 8-4 AWG Al wire. It is compatible with Siemens PL and ES series load centers and easily plugs in, fitting in a 2' space. But, of course, it also means that things work while you’re on the road or between stops. This RV circuit breaker is a 50 amp double-pole type 240 volt type circuit breaker and has a 10,000 AIC interrupting rating. This is here to make sure everything works when you aren’t plugged in or are boondocking or off the grid. It is available in different AMPs but includes a 30 AMP option and a 50 AMP if you have a larger motorhome. The next RV breaker box on our list is the Siemens TL137US Talon 30 AMP Breaker Box. The DC (Direct Current) system is the one that runs off of the batteries. Siemens TL137US Talon 30 AMP Breaker Box. Your RV electrical system probably has two separate power circuits, which can make things doubly confusing. ![]()
