When I connect the shorepower cord to dockservice that has the GFI
breaker, it trips when I try to run anything larger than a small
TV (200 watts). I must not have a suitable ground on the boat or
????. However, I plug one of the small AC test plugs into my boat
outlets and it indicates that all is well. I am not sure where
to start. Thanks for the responses.

I'd would say first, find the load value (amp rating) of the breaker.
It may be very low.. If its 15 amps or greater, and the plug from the
GFI to the boat is fine, you got to start isolating the stuff in the
boat. A simple ground/wiring/excess water problem will trip it.

Or plug one of the high draw appliances directly into the shore power
box to see if the box is ok.

I PLUGGED A HAIR DRYER (1500 WATTS) DIRECTLY INTO THE SHOREPOWER. IT
WORKS O.K.

So the shorepower appears OK. Carefully inspect the plugs on your
shore power connectors. Corrosion will cause resistance which could be
causing the breaker to trip. From there, check any connetions between
there and the power box on the boat. Undo any wire nuts on connections
and check for corrosion. Check the box mounting screws for corrosion -
these may be part of the grounding system of the boat. Of course, do
this stuff with the power off. If you have multiple circuits on the
boat, try the hair dryer in different circuits to see what happens. If
you are comfortable with doing electrical wiring, you might attach a
temporary receptacle to the dedicated circuits and try the dryer there.
Most likely there is corrosion on a connection somewhere, so keep
looing and undo and redo each connection, as this can reestablish a
good electrical path.
Good luck.
