Why the SmartPlug

The Problem with "Old School" NEMA Connectors

  • Curved pins: Electrical pins' curved shape causes minimum metal-to-metal contact, causing resistance and overheating
  • Connector body shape: The gap between the body and the inlet allows the connector to move, putting tension on the pins and clips
  • Ease of use: Difficult to find the "L"-shaped pin to twist and engage the plug, especially at night
  • Locking: No locking feature or plastic locking ring that is prone to stripping or cracking

The SmartPlug Solution

  • 50-Amp overheat protection: Oversize power pins and clips ensure efficient transfer of power even with high amperage loads
  • Electrical pins: Straight pins, not curved, with 20-times more electrical surface area; No twisting required
  • Better metal: All external metals are 316 stainless steel; electrical pins are nickel-plated brass for maximum connectivity
  • Connector body shape: Sleeve design fits snugly within the inlet, removing all pressure and tension from pins and clips
  • Weatherproof seal: TPE Dyna-flex cord seal ensures weatherproof seal to power cord
  • Locking: Inlet cover snaps onto the sides of the inlet and the top of the connector
  • Ease of use: Unique plug body shape only goes in one way, the right way; Plug pushes straight in and locks automatically with spring-loaded side clips
  • Industry-standard hole pattern: Mounts using the same hole pattern as industry-standard layout used by Hubbel, Marinco etc.
  • Indicator Light: Cool blue LED Power indicator light on the top of the connector glows when power is on
