Product details:

This 30 Amp transfer switch can be mounted next to the existing load center to power a single circuit such as a water heater well pump or small air conditioner during a power outage. By installing a transfer switch at the electrical panel you eliminate the possibility of dangerous back feeds or electric overloads. Its NEMA 3R corrosion resistant aluminum enclosure has a hinged cover for added protection from the elements. When the power goes out simply plug a standard grounded extension cord into the power outlet on your generator and into the built-in plug on the transfer switch. UL listed for US and Canada.
