Go Power 30 Amp Transfer Switch 64403

Provides automatic power switching between two separate 120 volt AC input sources. Some inverter installations integrate the inverter directly into the AC electrical system. An automatic transfer switch is usually installed to allow both your inverter and shore power to alternatively feed the circuits and prevent AC back feed. Automatically connects shore power (when available) to your breaker panel. When unplugged from power, it then connects your inverter output to power your circuits.GPTS: Prewired and circuit protected version of the TS-30. Includes a cable with built-in plug to connect the inverter output and a receptacle that powers your converter only when shore power is available.
