One of the functions of an isolation transformer is for galvanic isolation and then the local earth must be DC isolated from the marina earth
[/ QUOTE ] Many thanks. For me, that's the last brick in the wall. I've got it!
One assumption (which clouded understanding in parts of this thread) was that 'mother earth' - or water - was always a return for any AC live line - even if the other phase wasn't connected to earth by any means whatsoever. There seem to be exceptions.
Now I'm just going out to grab that live wire from the genny to test that assump !#**** sizzle zappppp
The archangel says I should have used a voltmeter . . .
