Dockside power issue

[steve c]

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?

With a splitter are you using two 30 amp outlets to plug into? Anytime I try to use a 30 amp outlet even with a smart Y I end up tripping the stump breakers. These old girls like their power.

The splitter has worked fine at this slip for the last 9 years.

1) Do you have an isolation transformer? If so, your boat is not the problem. It can't be because you don't even bring the neutral on board your boat.

2) I have been to a marina with a similar setup for part of a year and when I tried to use the smart Y it tripped their system. I ended up building my own reverse Y without the brain box and it worked just fine.

Are you plugged into 2 30 amp plugs? If not you’re only bringing in limited power. Is your splitter a 50/125 or a 50/125/250?

2 30 amp cords to 30 amp dockside connected to a 50 amp splitter. Same
boat and hookups for 9 years. Only difference is new service at the dock. The marina
claims new codes require a change at the boat. Dozens of boats at the marina are having
similar issues. The claim is that new electrical codes are causing the problem with many
of the boats.

Sky: how did you put together the splitter w/o the brain ?
