MARINE ISOLATION TRANSFORMERS

OVERVIEW

In 2017 NEC lowered the maximum permitted ground fault protection for boats on shore-power from 100mA to 30mA

Leakage current varies from boat to boat. Unfortunately, even with all electrical systems in good working order it will often exceed 30mA. This will trip the GFI circuit breaker in the pedestal and leave the boat without power.

The solution is to install a Marine-Puck on your boat

Our Marine-Puck family recently acquired UL Marine certification for the US and Canada.

Marine isolation transformers eliminate shock hazards to persons on board and in the water adjacent to the boat. They also eliminate possible galvanic corrosion of metal hulls and propellers due to DC currents traveling through a shore ground connection, as well as nuisance tripping of GFI (ground fault interrupt) systems when on shore power.
