Couple of wiki articles for your delectation and comments:


Excellent stuff John - thanks for your efforts.
One minor comment which may or may not be covered in the reference info is
the fact that your "shorted plug" will knock out all ciruits protected by a
common RCD.

That is a good point. I was trying to find a more "consumer friendly"
way of testing that did not involve opening the CU and disconnecting
wires there, and so came up with the plug based solution. Originally I
linked just L to N, but later when writing the bit on finding CPC
related faults the link to Earth came in handy. However that does
connect N to E indirectly.

Or maybe it's taken as read that all ciruits will be isolated not just the
subject one.

I shall spell that out a little more.

Cheers,
