Just wanted to say thanks for all the helpful advice i have received from the forum on this project...I now have working shore power on the boat.
Previously, the wire from the shore power split to two smaller wires which were connected directly to the (non GFCI) outlets on either side of the boat. I didn't dare plug in the shore power cable.
I stripped this out, installed a circuit breaker and galvanic isolator next to the shore power inlet. Put in an AC switch panel and replaced the first outlets either side with GFCI protected outlets. Tested as per Nigel Calder's instructions, plugged in, and we now have power. Trickiest bit was making a new teak outlet cover after snapping the previous one whilst trying to adapt it to the GFCI outlet
