Renogy 120V 30 Amp Automatic Transfer Switch

The Renogy 120V 30 Amp Automatic Transfer Switch shifts your AC loads from one power source to another on its own, so there is no need to flip a manual switch when a source becomes available or drops out. It is designed to fit a wide range of applications that rely on more than one source of 120V power. It uses a relay-based design with a built-in time delay of roughly 20 to 30 seconds before the transfer takes place. The heat-resistant ABS housing offers ten knockout holes and four mounting apertures for a straightforward install, and the switch is ETL listed and rated for 30A at 120VAC. Because it involves AC wiring, Renogy advises having it installed by a qualified electrician in line with local electrical codes.
