Understanding RV Electrical Adaptors



If you fail to understand the electrical adaptors on your RV, you could seriously damage its electrical system.

50 Amp vs 30 Amp vs 15 Amp

Your RV can be plugged into a 15 amp adapter. This kind of adapter is not always needed, but it’s nice to have them around. A 15 amp male RV electrical adapter comes with a 30 amp female plug. 

A 30 amp adapter can also be converted into a 50 amp adapter. Using a female adapter to convert a 50 amp adapter to 30 amps may be possible. Combo adapters are not the only ones available on the market.

Is your RV amp-ready?

Your RV’s amps can be checked using a few simple methods. Check the breaker box first. Labels or stickers should clearly state the information inside the breaker box. Your RV’s power cord tells you whether it is a 30 amp or 50 amp model. 50 amp RV cords have four prongs, while 30 amp RV cords have three.

Adapter plugs vs. dog bones

Plugs and cords for RV adapters differ slightly in a few simple ways. Dog bone connectors separate connection points with cords. An RV adapter plug usually features a female connector on one side and a male connector on the other. As compared to the previous piece, this one is more compact. It is also common for RV electrical adaptors to be curved at an angle of 90 degrees. It is easier to connect certain types of RVs to power sources than others.

RV electrical adaptors

Connect your RV adapters to the RV’s power cord. If you own a 30 amp RV, you should purchase an adaptor. Keeping them in the toolboxes on board is a good idea. Lack of options is the worst. Background shows several types of electrical adapters, while a hand holds an adapter plug in the foreground.

Plugging in your adaptor will change it. The main power cord of your RV should be plugged into the female end of the adaptor. Connect the male end of the adaptor to the power pedestal at your campsite.
