If you’re planning a camping trip in your RV or campervan, you’ll need to make sure you have the right wiring setup. A 30 amp RV plug is the most common type of connection used for RV’s and campervans, and it’s important to understand how to install and maintain it. In this guide, we’ll cover the basics of wiring a 30 amp RV plug, from finding the right wiring diagram to understanding the different components of the plug. We’ll walk you through the steps of wiring the plug, from stripping the cable to connecting the plug to the power source.

Choosing Your Wiring Diagram

The first step in wiring a 30 amp RV plug is to choose the right wiring diagram for your RV or campervan. Wiring diagrams are available online, and they’ll show you the right connections and components for your particular type of RV or campervan. Make sure you read through the instructions thoroughly before you begin wiring, and follow the diagram closely to ensure you make the right connections.

Stripping the Cable

Once you’ve chosen the right wiring diagram for your RV or campervan, you’ll need to strip the cable. This is the process of removing the outer insulation from the cable so you can access the wires inside. You should use a specialized wire stripper for this step, as it will make it easier to get the right depth and width of stripping. Be sure to pay attention to the wire colors and the location of the wires inside the cable so you can make the correct connections later.

Connecting the Wires to the Plug

Once you’ve stripped the cable, you’ll need to connect the wires to the plug. The first step is to attach the neutral wire to the silver terminal, and the ground wire to the green terminal. Then, you’ll need to attach the black and red wires to the two brass terminals. Make sure you attach the wires securely, as loose wires can cause problems with your electrical system.

Securing the Plug

Once you’ve connected the wires to the plug, you’ll need to secure it. To do this, you should use a screwdriver to tighten the screws on the sides of the plug. This will ensure the plug is secure and won’t come loose during use. Make sure you don’t over-tighten the screws, as this could damage the plug.

Connecting the Plug to the Power Source

Once the plug is secured, you’ll need to connect it to the power source. This can be done by attaching the plug to an appropriate power outlet or by connecting it to a power inlet box. Make sure you use the right type of cable for the job, as different types of cables are rated for different power levels. Once you’ve connected the plug to the power source, you’re ready to start using your RV or campervan.

Safety Considerations

When wiring a 30 amp RV plug, it’s important to consider safety. Make sure you wear protective clothing, such as safety glasses and gloves, to protect yourself from sparks and shocks. Additionally, make sure the area around the plug is clear of any combustible materials. Finally, make sure you turn off the power before you begin wiring, to prevent accidental shocks.


Wiring a 30 amp RV plug can seem intimidating, but it doesn’t have to be. With the right wiring diagram and a few simple steps, you can have your RV or campervan up and running in no time. Just be sure to take all necessary safety precautions, and you’ll be ready to start your next camping trip with ease.
