Prompted by a comment in this thread: Have you ever done it like this?
I thought it would be worth airing some opinions on the purpose of 'earth sleeving':
(a) According to BS 7671 (what Regulations require it, and for what purpose?)
(b) According to other risk reduction measures
Ages ago when ring final 13 Amp sockets were protected by 30 Amp. fuse wire, and R.C.D.s were not used, I came upon a socket where the unsleeved and uninsulated three strand tinned copper earth wire had come into contact with the live conductor/terminal of the socket. Yes it was called live back then. Live was red and neutral was black. I seem to remember that at least one if not two of the earth wire strands had completely burned through and were broken. Such was the power of a live to earth fault. P.V.C. earth sleeving would have prevented that incident.
The type of cable is shown above.
