SmartPlug’s 50A 125V/250V inlets have been designed to be used with 3-wires (125V) or 4-wires (250V) in a single inlet. The inlet connector provides 20X’s more electrical contact area eliminating the overheating conditions seen with twist-type connectors. The solid sleeve connection and weatherproof seal makes it a preferred option. The mounting flange holes match existing inlets so it can be easily installed to replace the old twist-type inlet products in minutes. The inlets are available in stainless steel and three non-metallic colors, (White, Black or Gray), of high performance/flame resistant material.
