Or, of course, leave out the last step (anything to do with Earth). That
would certainly solve my immediate problems :-)
But yes, you're quite right here. I've been thinking about this in terms
of Residual Current measuring, because it's an RCD tripping. I expect we
have bigger problems if we are leaking current anywhere *but* to the Earth
line, so perhaps I should redirect my searches to "inline earth leakage
ammeter" or something (making up our own device as you suggest above is
probably not an option...)
