The issue of the current flowing over EGCs on boat shore lines has come up elsewhere. I realize that the wiring of water craft is totally beyond the scope of the electric code but we had two people drown here recently when the leaking ground current caused people swimming near a dock to loose control of their bodies. Can anyone here tell me what standards do apply to the power systems on water craft. How would a responsible marina operator address this hazard. If they are functioning in a competitive environment how can local AHJs assure that the transfer equipment used on the boats transfers the grounded conductor (neutral) along with the Equipment Grounding Conductor?
