What is a motorhome transfer switch?

ATS is an abbreviation for automatic transfer switch, and its job is to be a traffic cop between the pedestal shore power and your on-board generator power. They come in two sizes: 30-amp and 50-amp RV power. They can also include a built-in surge protector. Some also have EMS under/over voltage protection.

How do I know if my transfer switch is bad?

You will want to check to see if the shore power is getting to the switch. If power is getting to the switch but not going into the RV, then it is the switch. Generally switches will go bad on the shore power side but will still work on the generator side.

What is the difference between ATS and STS?

A Static Transfer Switch (STS) utilizes a static electronic component (SCR), which permits a transfer in less than four milliseconds (1/4 of an electrical cycle). On the other hand, an Automatic Transfer Switch (ATS) relies on moving parts, and makes a significantly slower transfer than Static Transfer Switches.

Should I disconnect my RV battery when not in use?

Parasitic loads like gas detectors, clocks, and other small electrical devices drain power when your RV isn’t in use. If the power gets too low, it can hurt battery life. Your RV should be equipped with battery disconnect switches to prevent this, so don’t forget to engage them when the RV is off or in storage.

Should I leave my RV inverter on all the time?

Leaving an inverter on ensures continuous AC power which means you won’t lose any settings (such as clock settings) on devices like alarm clocks or microwaves. While traveling, you’ll want to leave an inverter on if you plan to charge your laptops and other devices on using standard wall chargers.

What are the components of automatic transfer switch?

The automatic transfer switch equipment includes a changeover switch made of two contactrs, an automatic mains failure controller , terminal blocks, power relays and miscellaneous electrical components like fuses, battery charger and electronic interface boards .

What is a RV transfer switch?

A recreational vehicle, or RV, will typically have two methods of introducing 120 volt electricity; a shore power cord and a generator. A transfer switch is a device which automatically switches between the power supplies to ensure both are not introduced to the vehicle simultaneously.

What is a 50 amp transfer switch?

The TRC 50-Amp automatic transfer switch is a basic transfer switch that automatically transfers to generator power 30 seconds after generator start-up. It ensures generator outage voltage is stable before powering up appliances plus once the generator is shut down shore power activates after a 3-4 second delay.

How does automatic transfer switch work?

An automatic transfer switch is basically a three way switch that switches between two inputs and connects them to a single common output. A transfer switch is located prior to the breaker panel. It intercepts the shore power cord feed to the breaker panel.
