The right solution is a dedicated RV electrical hookup — a properly sized circuit run from your panel to a weather-rated outlet or power pedestal near your RV pad. Swamp Rabbit Electric installs RV hookups for homeowners across Greenville, SC and the Upstate. With over 20 years of electrical experience and the kind of code-strict training that comes from 16 years working in New York City, we make sure your hookup is sized correctly, wired safely, and built to handle everything your RV can draw.
The answer depends on your rig, but here's the quick version:
A 30-amp hookup runs on a single 120-volt circuit and uses a NEMA TT-30 receptacle — the three-prong outlet you see at most campgrounds. It provides enough power to run your AC, fridge, lights, and a few smaller appliances, but not all at the same time.
A 50-amp hookup runs on a 240-volt circuit with two hot legs, providing significantly more power. It uses a NEMA 14-50 receptacle — the same four-prong outlet used for electric ranges and EV chargers. With 50-amp service, you can run two air conditioners, the microwave, the water heater, and the entertainment system simultaneously without tripping a breaker.
Every RV hookup we install is built to the same standard we'd want at our own property — properly sized wire, weatherproof connections, GFCI protection where required, and clean conduit runs that don't look like an afterthought bolted onto the side of your house. This isn't extension-cord-and-a-prayer territory. It's permanent, permitted electrical work done by a licensed electrician.
We install a dedicated circuit from your electrical panel to a weather-rated RV outlet at the location where you park your rig — your driveway, carport, RV pad, or side yard. The circuit is properly sized with the correct gauge wire for the amperage and distance, protected by the right breaker, and terminated in an outdoor-rated receptacle or GFCI-protected outlet.
For a more permanent setup, we install freestanding RV power pedestals that include 50-amp, 30-amp, and 20-amp outlets in a single weatherproof enclosure — just like what you'd find at a campground. The pedestal mounts on a post near your RV pad and includes its own breaker panel for circuit protection. This is the best option if you use your RV hookup frequently, host guests in their RVs, or rent your pad to traveling RVers.
If your main panel is far from where you park your RV, running individual circuits over long distances gets expensive and inefficient. In these cases, we install a subpanel closer to the RV pad and feed it from the main panel with a single, properly sized feeder cable. The subpanel then distributes power to the RV outlet, any exterior lighting, and other circuits you may need at the pad.
Before we install anything, we check your home's electrical panel to make sure it has the capacity and available breaker slots to support the new RV circuit. A 50-amp RV hookup is a significant load — the same as adding an electric range to your home. If your panel is full or near capacity, we'll discuss your options, which may include a panel upgrade or a load management approach.
If you already have an RV outlet but it's undersized, damaged, improperly wired, or was installed without a permit, we can repair or upgrade it to meet current code. One issue we see regularly is 30-amp TT-30 receptacles wired to a double-pole 240-volt breaker instead of a single-pole 120-volt breaker — a dangerous mistake that sends 240 volts to an RV designed for 120 and burns out appliances within seconds.
Here's what to expect when Swamp Rabbit Electric installs your RV hookup:
We visit your property, confirm where you want the outlet or pedestal, measure the distance from your panel, and check your panel's capacity. This tells us exactly what the job requires and what it will cost.
We select the correct wire gauge based on the amperage and the length of the run. Longer distances require heavier wire to prevent voltage drop — something that gets overlooked in DIY and handyman installations. We also plan the conduit route, whether it runs along the exterior of the house, through a crawlspace, or underground.
We install the breaker, run the wiring through conduit, mount the outlet or pedestal, and make all connections. Underground runs are trenched and run in schedule 40 PVC conduit at the required burial depth. Everything is weatherproofed and GFCI-protected where required by code.
Before we leave, we test voltage at the receptacle under load to confirm the outlet is delivering the correct power — 120 volts for 30-amp service, 120/240 volts for 50-amp service. This step catches wiring errors that could damage your RV's electrical system.
RV electrical hookups in Greenville County require an electrical permit for new circuit work. We handle the permit and schedule the inspection.
"Danny has done several jobs for us on our new home. Like a 30 amp panel box to plugin our RV and a surge protector on our main breaker. We have always been super happy with his quality of work and attention to detail. I have also referred him to many of my neighbors and always hear positive feedback. It's nice to have a reliable electrician that knows what he's doing."
"Daniel is a prince. Professional, on time, great work, and reasonably priced. We will never call anybody else for electrical work!"
"Daniel responded quickly, arrived on time, and did a thorough and meticulous job. I will be hiring Swamp Rabbit Electric again to meet any electrical needs I have in the future."

Whether you're searching for an electrician near you, emergency electrical repair, panel upgrades, EV charger installation, or lighting services in Greenville—you're in the right place.
A standard 50-amp RV hookup with a short to moderate wiring run typically costs between $500 and $1,500 for the electrical work, depending on the distance from your panel and whether the run is above ground or underground. Longer runs, subpanel installations, and panel upgrades will increase the cost. We provide a written quote after the site evaluation.
You can with an adapter, but you'll be limited to 15 or 20 amps — barely enough to run the lights and charge batteries. You won't be able to run the air conditioner, microwave, or most major appliances. A dedicated 30- or 50-amp circuit is the only way to use your RV's full electrical system at home.
Yes. Adding a new dedicated circuit requires an electrical permit in Greenville County. The work must be inspected before it's considered complete. We handle the permitting process for every job.
There's no hard code limit on distance, but longer runs cost more because they require heavier gauge wire to compensate for voltage drop. Runs under 100 feet are straightforward. For longer distances, a subpanel closer to the RV pad is usually the more cost-effective and reliable solution.
We almost always recommend 50-amp. The labor cost is the same, the wire and breaker cost only slightly more, and you'll have the flexibility to power any RV — yours or a guest's — without limitations. A 50-amp pedestal with a 30-amp and 20-amp outlet covers every use case.
Yes. We install RV hookups for property owners who want to offer RV-friendly accommodations or add an RV pad as a secondary rental space. The installation is the same — dedicated circuit, weather-rated outlet or pedestal, and proper permitting.
Whether you're prepping your travel trailer for the season, setting up a permanent pad for your motorhome, or adding an RV hookup to a rental property, Swamp Rabbit Electric installs it right — correct amperage, proper wire gauge, code-compliant, and tested before we leave.
