The 50A 125V/250V connector has been designed to be used with 3-wires (125V) or 4-wires (250V) in a single connector.  Our retrofit connector offers superior performance and ease of use. The SmartPlug connector is designed to use your current cord set. You simply cut off the cord plug on your RV/Boat 50A cord.  The connector has mechanical cord restraint, color-coded wire guides, a water-resistant cord seal and spring loaded side levers that automatically lock into the slots on the inlet housing.

• Eliminates Overheating – Increased pin & clip surface area greatly improves electrical conductivity during high amperage demand.
• Ease of Use – No twist required, the unique plug body shape and push-in design mean it only goes in the right way every time – even in the dark!
• Multi-Point Locking System – Side clips lock the plug securely into the inlet which eliminates any stress on the pins from the movement of the power cord.
• Weatherproof Seals – Multi-fin silicone gaskets installed in the inlet cover and interior of the plug body eliminates moisture penetration.
