What do you require a functional earth for?
Think the OP is getting confused with his terminology but the way he wrote it he means the sub-main earth for circuit protection, not of course a functional earth which relates to a different meaning.
It's the experience you have when you're out of your tree on LSD.
Sorry to hear that,fella. Maybe that explains that back garden of yours,full of beautiful poppies...:smilewinkgrin:
