Additional Campground Considerations

Checking Campground Specifications

Before booking a site, always check the campground’s electrical offerings. Some older campgrounds may only offer 15/20 Amp service, while others might have 30 and/or 50 Amp options. Knowing what’s available helps you plan accordingly and may avoid disappointment later.

Adapter Usage

Sometimes, you might find yourself at a campground where the available amperage doesn’t match your RV’s needs. In such cases, adapters can be a lifesaver. For example, if your RV requires a 50 Amp hookup but only 30 Amp service is available, a 30-to-50 Amp adapter can bridge the gap. However, remember that using a 30 Amp adapter means you will only have 30A of power available, even if it is plugged into a 50A receptacle, so manage your usage accordingly. If you try drawing more power than 30 Amps, your adaptor and other electrical appliances may be damaged. 

Power Management

Regardless of the available amperage, efficient power management is key. Avoid running multiple high-wattage appliances simultaneously. Use appliances like air conditioners, microwaves, and electric heaters sparingly to prevent system overload.

Safety Precautions

Always inspect the campground’s electrical pedestal before plugging in your RV. Look for signs of damage, wear, or black burn marks. Campground power supplies can be susceptible to low voltage during high-draw periods and improperly wired connections, which can damage RV appliances. 

I strongly recommend a surge protector to protect your RV’s electrical system from potential power surges or faults. Advanced surge protectors will also alert you to wiring issues before damage occurs. If you notice any issues with the power pedestal, report them to the campground management before plugging in.

Peak Usage Times

Be aware of peak usage times, especially in crowded campgrounds. During peak hours, power demand can be high, potentially affecting the stability of the electrical supply. Plan your high-power activities during off-peak hours when possible.

Site Selection

Choose a site that best matches your RV’s power needs. If you have a larger RV with higher power demands, ensure the site you select offers 50 Amp service. A 30 Amp or even a 15/20 Amp site may suffice for smaller RVs or those with fewer power requirements. Some parks charge by how many Amps you are plugged into, so why pay for 50 Amp service when 30 Amp will suffice?

Understanding campground electrical hookup configurations and considerations can ensure a smooth and safe RVing experience. Proper planning and preparation will help you make the most of your stay, whether at a rustic campsite with minimal amenities or a modern campground equipped with all the comforts of home.

Installing an RV Receptacle at Home: Bringing the Campground to Your House

Publishers Note:  If you are unfamiliar with high-voltage electricity, we strongly suggest you hire a licensed Electrician to install a remote receptacle at your home for your RV.  This is high voltage, and one mistake during or after the installation can be deadly. Hiring a licensed electrician can provide peace of mind and ensure the job is done correctly and safely and best protect your RV.

Installing an RV receptacle can be a game-changer for RV enthusiasts who want to plug their rig into 30 or 50 Amps at home. This section will guide you through the step-by-step process to set up a 30 or 50-amp RV outlet at your residence, ensuring you can conveniently power your RV without leaving your driveway.

Step 1: Choose the Location

Select a convenient location near where you park your RV, or where a visiting friend may park their RV. Ensure it is accessible and close enough to your main electrical panel to minimize wiring complications.  The longer the distance to the main power supply in your house, the higher the voltage drop.  It's best to choose a location sheltered from the elements to protect the outlet from rain and debris.

Mount the outdoor-rated electrical box at your chosen location. Secure it properly to withstand outdoor conditions and ensure it is easily reachable from where your RV will be parked. If mounting on an exterior wall, ensure it is well-anchored and sealed to prevent water ingress. Mount it at a height where you can easily plug it in and unplug it, as they sometimes stick. Try to avoid mounting your receptacle where a puddle may pool underneath. 

Step 4: Run the Conduit and Wiring

From your main electrical panel, run the conduit to the location of the electrical box. Inside the conduit, pull the appropriate gauge wire for your chosen amperage. For a 30 Amp service, typically a 10-gauge wire is used, while a 50 Amp service requires a 6-gauge wire. Note:  For longer runs than average, larger gauge wire may be required due to a loss in resistance. Plan the conduit route carefully to minimize bends and turns, making it easier to pull the wire through. Use appropriate fittings to secure the conduit to the wall, and the electrical box and the main panel.

Step 5: Install the Circuit Breaker

Turn off the main power supply before working in the electrical panel. Install the appropriate breaker (30 Amp or 50 Amp) into your main panel. Connect the wiring to the breaker, ensuring all connections are tight and secure. Label the breaker clearly in your panel to avoid confusion later.

Step 6: Connect the Outlet

Connect the wiring to the RV outlet according to the manufacturer’s instructions. Ensure all connections are correct and secure and it is properly grounded. Follow the outlet manufacturer’s instructions closely. Ensure the ground wire is properly connected to the grounding terminal. Double-check all connections before proceeding to the next step.

Step 7: Test the Installation

Once everything is connected, turn the power back on and test the outlet with a multimeter to ensure it’s providing the correct voltage and polarity. Plug your RV in and test the systems to confirm they work correctly. Verify that the correct voltage is present and that there are no issues with grounding. Test the outlet by plugging in your RV and turning on one or more high-wattage devices to ensure it handles the load without tripping the breaker.

Safety Considerations

Always adhere to local electrical codes and regulations. If you’re uncomfortable working with electricity, hiring a licensed electrician to perform the installation is advisable. Safety should always be your top priority. Electricity is dangerous, and proper installation is crucial for safety. A licensed electrician can ensure your setup meets all local codes and regulations.
