Exporting earths

[Deleted member 9648]

This old chestnut has surfaced yet again on a thread.....can someone please explain to me why otherwise sensible and knowledgable sparkies seem to go into a panic as soon as 'garage' or 'shed' is mentioned and suggest a rod?...and yet those same sparks will happily install outside lighting,outside sockets and other stuff back to the house CU without even a mere suggestion of the dreaded 'exported earth' and a rod......I've never been able to understand the thinking behind it,can someone enlighten me please?

on a more light-hearted note, my view is that the only cord on a garden tool is the one you pull to start it

TN-C-S if you check out the post from widdler above your previous post, you'll see the missing 'S' in red!

Since i actually quoted Widdler's post in my reply it might be logical to assume i had noticed it. My confusion was whether he meant to include any earthing arrangement with the letters TNC as i had previously said that i was unaware of the use of TN-C in the UK and am not familiar with it or the earthing arrangements of farms. J@mes' input has sorted it though.

No problem, I never assume anything on forums!
