How to Wire a 50 amp RV Plug to a Breaker Box? My Step-by-Step Guide

Wiring a 50-amp RV plug to a breaker box is a common and necessary task for many RV owners. As an avid RV enthusiast, I’ve undertaken this project multiple times, and I’m excited to share my experience and a comprehensive guide on how to get it done. 

In this article, I will explore when and why you might need to perform this task, the step-by-step process to do it safely and effectively, and the advantages and drawbacks of having a dedicated 50-amp RV hookup at your disposal.

When and Why You Might Need to Wire a 50-Amp RV Plug

Before we delve into the ‘how,’ let’s understand the ‘when’ and ‘why’ behind wiring a 50-amp RV plug to a breaker box.

New RV Purchase: If you’ve recently acquired a 50-amp RV, your existing electrical setup may not be sufficient, and you’ll need to upgrade to accommodate the higher power requirements.

Home RV Parking: When parking your RV at home or on a dedicated RV pad, having a dedicated 50-amp hookup can make your RV experience more convenient.

Increased Power Demand: If your RV adventures involve running multiple appliances simultaneously, such as air conditioners, ovens, and other power-hungry devices, a 50-amp hookup becomes essential.

How Do I Wire a 50-Amp RV Plug to a Breaker Box:

Now, let’s walk through the process of wiring a 50-amp RV plug to a breaker box, based on my personal experience.

Step 1: Turn Off the Power

• The very first step is to ensure your safety. Turn off the power at the main electrical panel to prevent electrical shock while working.

Step 2: Choose the Location

• Select a suitable location for your 50-amp RV receptacle. This should be accessible and not exposed to direct weather. I chose a location on the exterior wall of my garage for easy access.

Step 3: Mount the RV Receptacle

• Follow the manufacturer’s instructions to mount the RV receptacle. Ensure it is positioned at least 18 inches above the ground and adequately supported. This is crucial to protect the connection from moisture and damage.

Step 4: Run the Wiring

• Choose the appropriate gauge of wire. In my case, I used 6-gauge wire for a 50-amp service.
• Connect the wires to the RV receptacle. You’ll typically have two hot wires (red and black), a neutral wire (white), and a ground wire (green or bare copper).
• Run the wire from the receptacle to your breaker box, using conduit or cable protectors as needed, especially if the wire is exposed to the elements or areas where it could be damaged.

Step 5: Connect the Wiring to the Breaker Box

• Carefully open the breaker box.
• Connect the ground wire (green or bare copper) to the ground bar in the breaker box.
• Connect the white neutral wire to the neutral bar.
• The red and black hot wires should be connected to the two terminals of the 50-amp double-pole circuit breaker. Secure these connections with wire connectors and tighten the screws.

Step 6: Attach the Circuit Breaker

• Insert the 50-amp circuit breaker into the breaker box.
• Ensure it is securely attached to the bus bars.
• Close the breaker box cover.

Step 7: Test and Turn On Power

• Before turning on the power, double-check all your connections to ensure they are secure.
• Turn the power back on at the main electrical panel.

Step 8: Test the RV Receptacle

• Plug your RV into the newly installed receptacle.
• Verify that it receives power without any issues. Test various appliances and systems to ensure everything is functioning correctly.

Step 9: Final Safety Check

• Perform a final safety check. Look for any exposed wires and ensure all connections are secure.
• Advantages and Drawbacks of Wiring a 50-Amp RV Plug
• It’s important to understand both the benefits and potential drawbacks of wiring a 50-amp RV plug.

Other Popular Queries

• Can I wire a 50-amp RV plug on my own? 

While it’s possible to do it yourself, it’s essential to have electrical knowledge and experience. If you’re not comfortable with electrical work, it’s safer to hire a licensed electrician.

• What type of wire should I use for a 50-amp RV hookup?

Yes, you should use a double-pole 50-amp circuit breaker for this purpose.

• Can I convert my existing 30-amp hookup to a 50-amp hookup? 

Converting from 30-amp to 50-amp service may require rewiring and a new breaker box, and it can be complex. Consult with an electrician for such conversions.

Final Thoughts

Wiring a 50-amp RV plug to a breaker box is a valuable upgrade for RV owners who require more power, desire safety, and convenience, and wish to maximize the utility of their RV. While it can be a DIY project for those with electrical experience, safety should always be a top priority. If in doubt, consult with a licensed electrician to ensure your installation is both safe and code-compliant.
