Power inlet boxes run power to critical electrical systems, while avoiding harmful exhaust fumes that a generator produces. Simply mount the box on the exterior of your home / business, and run the wiring to a transfer switch / box installation. When emergency power is needed, connect a generator cord to the inlet box, and flip the switch for the transfer unit. These boxes are equipped with a L14-30 male configuration rated for 30 amps, 125/250V. There are several different finishes of inlet boxes that are all corrosion resistant powder coated steel to choose from. Each inlet features a protective cap that creates a watertight seal when not in use. 1-Year Limited Warranty
