Why Smartplug?

THE PROBLEM WITH THE ORIGINAL SYSTEM

The first cause of shore power failure and following fires is not electrical shorting, but rather overheating caused by poor electrical conductivity.
The shape of electrical pins allows 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. 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.
