I have been at the same marina for 30 years and in the same slip for fifteen years with no dockside ac issues. This year the marina installed new floating docks, water and power. My boat trips the gfi at the dock. Since there is no 50 amp recepta
cle I use a splitter. The marina claims that new electrical codes cause many boats to cause this problem
because the codes used when the boat was built different codes were in play. Their solution...my boat,
my problem. They sent an electrician ( marine ) who changed a ground in the dc box on the bulkhead
in the engine room and said a splitter would not work on the marina's system. $315 later he says there
might still be a problem since he can't test it until a 50 amp receptacle is installed on the dock.
Anyone else have experience with this?
