SmartPlug 50 Amp Non Metallic Gray Inlet & Plug Combo - Boat & RV. This Inlet 125/250V 4-wire design (250V only) is made with high performance/flame resistant plastic that is UV and corrosion resistant. Our SmartPlug Power Inlet and Plug will look and perform like new for years to come. In fact in one study our SmartPlug Power Inlet and Plug performed better than the original 4-wire and 4-wire conventional connectors used in the field. Our product has been designed so that it can be used with 3-wires or 4-wires and with our new bulkhead inlet and retro-fit connectors with 4-wires only The new bulkhead inlet has a more streamlined shape that aids in installation as well as in use. There is no twisting required either - just a simple plug-and-play installation. Our SmartPlug Power Inlet and plug combo kit is designed to be used in either the new build or the retro-fit configuration. The inlet is made of high performance/flame resistant plastic that's UV resistant and durable. There is a multi-point locking system (side clips and inlet cover) that locks the plug body securely into the inlet which eliminates any stress on the electrical components by the movement of the power cord. And there is a weather resistant seal (side clips and plug body) that allows the inlet and plug to be installed in wet or dry environments. Our gray inlet and plug combo set is made for non-metallic applications. There is no weatherproofing of the plug and most of the inlet components are installed to ensure the longest service life possible.
