The ENERLITES 66500M is a 50A receptacle box designed for outdoor use. Unlike the standard 66500 NEMA 14-50R outlet, the 66500M comes built into a heavy-duty lockable enclosure made from powder coated steel. This makes the power outlet box resistant to damage caused by heat, impacts, and year-round weather conditions. The NEMA 14-50R weatherproof receptacle is perfect for RVs, motor homes, electric vehicles (EV), generators, welding equipment, and more.
