A method and apparatus including indicators and a Ground Fault Current Interrupter (GFCI) are provided to test the marina's power and the boats electrical system load to make sure that both are proper and safe to be inter-connected. A low voltage high impedance ground current path including an oppositely connected pair of typically four silicon diodes in series in each of the pairs, sufficient to raise the voltage to a safe level encompassing the typical combined AC ground fault and DC galvanic currents in a Marina is incorporated. This protects against low level AC ground faults present in the marina, as well as DC current due to the harbor safety ground interconnect between boats in the harbor.
Apparatus for testing an electrical supply system comprising:
A method for testing a marina electrical supply system having AC lines and a marina wiring system for marine vehicles for personnel safety and avoiding electrical damage to components of said marine vehicle by the said marina electrical supply system comprising:
