The Problem
Contrary to popular belief, the #1 cause of shore power failure and fires is not electrical shorting, but rather overheating caused by poor electrical conductivity. How does this happen? The problems with many plug designs are that the shape of electrical pins allow for very little contact area, and the pins themselves are also largely responsible for bearing any physical stress placed on the cord (from constant movement of the boat, someone tripping on the cord, etc...)

This results in the pins working loose, further lessening the precious little contact area they had to begin with. Furthermore, such loose connections allow for moisture intrusion and ultimately corrosion of the pins. Arcing occurs and the connection heats up, scorches, and in some cases, catches fire. Because the current draw is unchanged, all of this happens long before a breaker or a GFCI can cut the power. Additionally, the old design can be very difficult to use in low light or hard-to-reach scenarios since the "L" shaped pin must first be located and then oriented before connection.

The SmartPlug Solution

  • Protection from overheating   Sleeve design and larger electrical pin surface area eliminates possibility of electrical arcing, and internal thermostat trips at the first sign of overheating.
  • Protection from electrical shorts   3 waterproof seals eliminate electrical shorts caused by corrosion and exposure to the elements.
  • A secure locking connection   Side locks and cover lock protect against loose connections due to movement or tension in the cord.
  • Ease of use   Straight electrical pin design means no twisting required and no possibility of misalignment.
