30 amp Automatic Transfer Switch

The Surge Guard 41300 Basic Automatic Transfer Switch is designed for RV electrical systems that use both shore power and generator power. When generator power is energized, the switch automatically transfers power after a 30-second delay, helping stabilize generator output before connecting loads.

When both shore power and generator power are available, generator power takes priority after the 30-second delay. Once the generator shuts down, the unit automatically transfers back to shore power after a 3–4 second delay.
