Shore power testing is there a good device out there?

Mike,

OK, now I get it, I have sent you an email for a 240v test cct, sorry I should have picked up on the three phase issue, I know you have had some painful experience of this. Will give it some further thought!

For anyone else interested something like the following, but it would be a good idea to fuse all three incoming legs! You could use a 10ma RCD and set R accordingly, most marina RCD's I expect are 30ma or above, no problem having two in line, many boats have them fitted anyway.
