SmartPlug: Safer Power
According to multiple reports, most AC electrical fires occur at the boat’s shorepower inlet. To address this and other shortcomings of the standard twist-type boatside connection, SmartPlug Systems developed a new AC shorepower system that the company hopes will become the new marine standard. Loose and corroded connections are most often the culprits when overheating occurs. Corrosion typically results when moisture gets in at the plug-inlet connection, while arcing—which in turn leads to pitting, scorching, and heat build-up—is partially due to the shape and small contact area of the connector pins.
