I have a number of 240v ac outlets around the boat - alongside they are powered from the marina shore power through a 32A Marinco connector and via a breaker on the switch panel - at sea the same set up but sourced from the onboard inverter
A few days ago the Earth Leakage breaker started to trip when running from shore power when I turned on the 240v outlets - other 240v powered equipment onboard (like the microwave and the battery charger) worked OK - I assumed it must be some sort of water ingress to one of the sockets after washing the decks
However although the earth leakage trip fires every time when running from shore power and when I turn on the outlets via the breaker - if I disconnect the shore power and run the same outlets from the inverter, everything works fine
The wiring to the sockets is the same for shore power and inverter and the earth (according to the diagrams) is common - the only difference is the source of the power
Im at a bit of a loss to understand what might be happening and would appreciate any thoughts ?
