shock

Got a new problem today. Purchased a nice new shinny chrome kettle. Plugged it into the shore power and got a belt off it, and popped the trips.
Reset the trip, switched it on and metered from the kettle body to earth and found it to be alive. Took the kettle home and tried it and all was OK, so the problem has to be in the shore power circuit, YET our old kettle is OK.
Any ideas please.

Was the old one three pin ? the new one two pin ?.

Sounds a bit like reverse polarity, with neutral linked to body of kettle. At home correct polarity so ok, on boat live to body, causes a fault blows trip.

Was the old kettle metal or plastic? could be a disconnected or poor connection to neutral at the socket .
Would be worth trying anther socket on the boat or plug into another shore power outlet to see if problem still exists, or check the live to earth to see if polarity reversed

THIS MIGHT HELP SOLVE THE PROBLEM

My old kettle was a standard type, the new is a cordless.
I have got mains tester + RCD trips on board, the new kettle does not trip these out, but the trip on the meter in the main supply box ashore does trip, but only after the kettle has boiled and flicks itself off.

It is the live body = metal, of the kettle that has me a bit worried, maybe it's back to plastic.

I think there is an Earthing issue with the shore power.

Good to know the trips work when you need them. An electrician friend of mine told me you can be electrocuted without even blowing a 3 amp conventional fuse.

Suggest you get an electrician friend to put a megger on your kettle.This puts a high voltage between connections and kettle body thro. a meter.If no megger available take the kettle back and change it.

If kettle meggers ok suggest you follow Halcyon advice
