As an RV owner, it is essential to understand how your electrical systems work. One of the most critical components of your RV electrical system is the 50 amp RV plug. With this, you can run your air conditioner, refrigerator, and other electrical appliances in your RV. In this article, we’ll discuss the 50 amp RV plug wiring diagram, including how to install it, troubleshoot it, and maintain it.
What is a 50 Amp RV Plug?
A 50 amp RV plug is a large, three-pronged connector used to power an RV. It has two hot wires, a neutral wire, and a ground wire, which runs from the plugin to your RV’s electrical system. The hot wires carry 120 volts of electricity each, while the neutral wire carries no electricity. The ground wire provides a safe electrical path for excess current and prevents shocks.
What’s the difference between a 30 amp and 50 amp RV plug?
A 30 amp RV plug has a single hot wire, a neutral wire, and a ground wire, which provides electricity to your RV. While a 50 amp RV plug has two hot wires and the neutral and ground wires. Therefore, 50 amp RVs can handle more electrical appliances than 30 amp RVs.
What kind of RVs use 50 amp plugs?
Most larger RVs and motorhomes use a 50 amp plug, while smaller trailers and pop-ups typically use a 30 amp plug. But it also isn’t uncommon for smaller rigs to use a 50 amp setup, as it provides more power and flexibility.
