What is an RV Automatic Transfer Switch and Why Do You Need One?

An RV automatic transfer switch (ATS) is a device that automatically switches between different power sources for your RV. Typically, these sources are shore power (electricity from a campground), a generator, and sometimes an inverter. Without an ATS, you'd have to manually plug and unplug your RV's power cord, which can be inconvenient and even dangerous.

Here's why you need an RV ATS:

• Convenience: The most obvious benefit is convenience. No more manually switching cables! The ATS detects the available power source and seamlessly switches to it.
• Safety: Manually switching power sources can lead to electrical hazards, such as backfeeding electricity into the grid, which can damage equipment and pose a risk to electrical workers. An ATS prevents this.
• Appliance Protection: An ATS provides a clean and consistent power supply, protecting your sensitive RV appliances from voltage fluctuations and power surges.
• Generator Compatibility: If you have a generator, an ATS makes it incredibly easy to use. When the shore power is disconnected, the ATS automatically switches to generator power, ensuring a continuous supply.

Buying Guide: Choosing the Right RV Automatic Transfer Switch

Selecting the right RV automatic transfer switch involves considering several factors. Here's a breakdown of the most important aspects to keep in mind:

1. Amperage Rating: The most crucial factor is the amperage rating. Your RV's electrical system is either 30 amp or 50 amp. You must choose an RV automatic transfer switch with the correct amperage rating to match your RV's service. Using an undersized RV automatic transfer switch can lead to overheating and potential fire hazards.

2. Number of Inputs: Determine how many power sources you need to switch between. Most RV automatic transfer switches have two inputs: one for shore power and one for a generator. If you have an inverter as well, you might need an RV automatic transfer switch with three inputs.

3. Time Delay: A time delay feature is highly recommended, especially if you have a generator. This feature allows the generator to warm up and stabilize before connecting to the RV's electrical system, preventing potential damage. A typical time delay is around 15-30 seconds.

4. Surge Protection: Consider an RV automatic transfer switch with built-in surge protection. This feature protects your RV's appliances and electronics from voltage spikes and surges, which can occur at campgrounds or when using a generator. If the RV automatic transfer switch doesn't include surge protection, you can purchase a separate surge protector.

5. Manual Override: Some RV automatic transfer switches have a manual override switch. This allows you to manually select the power source in case the automatic switching system fails. This can be a useful backup feature in emergency situations.

6. Installation: Consider your comfort level with electrical work. Some RV automatic transfer switches are easier to install than others. Look for models with clear instructions and labeled terminals. If you're not comfortable with electrical work, it's best to hire a qualified electrician to install the RV automatic transfer switch.

7. Build Quality and Durability: RVs are subjected to vibrations, temperature changes, and other environmental factors. Choose an RV automatic transfer switch that is built to withstand these conditions. Look for models with robust construction and high-quality components.

8. Certifications: Ensure the RV automatic transfer switch is certified by a reputable testing laboratory, such as UL or ETL. These certifications indicate that the RV automatic transfer switch has been tested and meets safety standards.

9. Price: RV automatic transfer switches range in price from around $100 to $500 or more. The price depends on the amperage rating, features, and brand. Consider your budget and choose an RV automatic transfer switch that offers the best value for your needs.

Installation Tips for Your New RV Automatic Transfer Switch

While professional installation is always recommended, here are some general tips if you plan to install the RV automatic transfer switch yourself:

• Safety First: Always disconnect the RV from all power sources (shore power, generator, and battery) before starting any electrical work.
• Read the Instructions: Carefully read and follow the manufacturer's instructions.
• Use the Correct Tools: Use the appropriate tools for the job, such as wire strippers, crimpers, and screwdrivers.
• Wire Gauge: Use the correct gauge wire for the amperage rating of the RV automatic transfer switch. Consult a wiring chart to determine the appropriate wire gauge.
• Secure Connections: Ensure all wire connections are secure and properly tightened. Loose connections can cause overheating and electrical problems.
• Label Wires: Label all wires before disconnecting them to make it easier to reconnect them correctly.
• Test the RV Automatic Transfer Switch: After installation, test the RV automatic transfer switch to ensure it is working properly.
