RV Transfer Switch Wiring Diagram: Everything You Need to Know

Are you looking to install an RV transfer switch but have no idea where to start? Don’t worry, we’ve got you covered. In this article, we’ll be discussing everything you need to know about RV transfer switch wiring diagrams. From the basics to FAQs, we’ve got everything you need to get you started.

What is an RV Transfer Switch?

Before we dive into the wiring diagram, let’s first understand what an RV transfer switch is. An RV transfer switch is an electrical component that allows you to switch between two power sources seamlessly. It is designed to automatically transfer your RV’s electrical load from the generator to the shore power and vice versa without interruption.

For instance, if you’re camping and want to use your RV’s electricity, you can connect it to the generator. But when you’re at an RV park, you can use their power supply instead. The transfer switch will detect which source is active and automatically switch the power source without you having to do anything manually.

Types of Transfer Switches

There are two types of RV transfer switches, namely manual and automatic. The manual transfer switch requires you to switch the power source manually, while the automatic transfer switch does the switching automatically.

Manual Transfer Switch

The manual transfer switch is ideal for those who frequently change their power source. It requires you to manually switch your RV’s power source using a physical switch. They are easy to install and come with a lower price tag than automatic switches.

Automatic Transfer Switch

An automatic transfer switch is ideal for those who want a seamless switch between power sources. It is meant for those who don’t want to do the switching manually. It automatically detects which power source is active and switches the power source without interrupting the electrical load. They are expensive than manual transfer switches, but their convenience is worth it.
