Not every campground pedestal matches your RV's power cord, and that mismatch can leave you without power when you are ready to set up camp. An electrical adapter is a simple and affordable solution that lets you connect to available shore power regardless of the pedestal configuration at your site.

Our selection of RV electrical adapters includes 30-amp to 50-amp adapters, 50-amp to 30-amp adapters, and standard household adapters for situations where only a 15 or 20-amp outlet is available. Before ordering, confirm your RV's shore power cord configuration so you select the correct adapter for your needs. Carrying more than one adapter is a practical habit that ensures you are covered at most campground setups.

Which camper plug adapter do I need for my RV?

Match the adapter to two things: the plug on your RV's shore power cord and the receptacle you are plugging into. A 30 amp RV uses a three-prong TT-30P plug; a 50 amp RV uses a four-prong 14-50P plug. Campground pedestals typically have TT-30R and 14-50R receptacles, and household outlets are 15 amp (5-15R) or 20 amp (5-20R). Check the prong layout on both ends before ordering. If you are unsure, text or call 817-984-1852 with your RV's power rating and we'll confirm the right adapter.

Can I use a 30 amp RV plug adapter at a 50 amp campground pedestal?

Yes. A 50 amp to 30 amp RV plug adapter plugs into the pedestal's 14-50 receptacle and accepts your TT-30P cord. Your RV still draws no more than 30 amps at 120 volts (about 3,600 watts), because its cord and breaker panel are rated for 30 amps. The adapter does not add capacity. Pedestal voltage can run low or be miswired, so pair the adapter with one of our Southwire Surge Guard RV surge protectors to cut power before a fault reaches your RV.

Can I plug my camper into a household outlet with an electrical adapter?

Yes, with a 30 amp to 15 amp camper electrical adapter (TT-30R to 5-15P). Your RV is then limited to 15 amps, roughly 1,800 watts. That covers lights, the refrigerator on electric, and battery charging through the converter, but a rooftop air conditioner will usually trip the household breaker. Do not plug a 30 amp RV into a 30 amp dryer outlet. Dryer receptacles (NEMA 10-30 and 14-30) supply 240 volts and can damage 120 volt RV appliances.

What is the difference between a dogbone RV plug adapter and a rigid adapter?

A dogbone adapter is a short cord with a plug on one end and a receptacle on the other. It takes weight off the pedestal connection and gives you a little extra reach. A rigid adapter is a single molded piece that sits directly in the receptacle. If your RV uses a detachable shore power cord that locks into a twist-lock inlet on the sidewall, see our RV detachable adapters built for detachable cord setups. Confirm whether your cord is hardwired or detachable before ordering.

How do I avoid tripping the breaker on a 30 amp RV adapter?

A 30 amp service supports one rooftop air conditioner plus light loads. Running the AC, microwave, and electric water heater at the same time can exceed 30 amps. Stagger high-draw appliances so they do not cycle on together. For live readings, Bluetooth RV surge protectors show voltage and amp draw on your phone, so you can see how close you are to the limit before the breaker trips.
