HI all.
Is 4mm internal diameter earth sleeving ok for wall sockets?

Thanks.

Depends on what type of wall sockets you have and how big your CPC
cables are.

Any earth sleeving which fits over the earth wire is fine - it doesn't
need to be a tight fit. 4mm is a good compromise size that can be used on
most domestic cable sizes.

It's for indication purposes only so as Dave says, any size that you can
poke the wire down is fine.

stupid question What is the earth sleeving for? Purely saying "this is
earth, not some live wire which has just lost the insulation", or more?

It not only indicates the earth but helps prevent the possibility of a
short in a tightly packed backing box, etc. At one time it wasn't required
so it's just one of those belt and braces thingies. But given the low cost
not worth even debating the merits of. Think I'm only on my second 100
metre drum in some 40 odd years of DIY and part time pro wiring.

partly that, partly to stop it wandering around inside the backbox and
touching a live terminal ...

That, and more. It prevents problems when you fold the wires up into a
back box. An uninsulated wire would be able to make contact with things
it should. In the case of contact with the live it would trip a breaker
or blow a fuse, but contact with the neutral could cause a number of
more subtle problems like nuisance tripping of a RCD.

We were somewhere around Barstow, on the edge of the desert, when the
drugs began to take hold. I remember "Clive George"
saying something like:

Insulate and identify.
I've seen some CUs and sockets which have had no earth sleeving on the
earth conductors, which were wandering around. Dodgy practice, indeed.

But used to conform to the then regs. You need to take more care with
routing, but should be safe enough.

Makes sense - ta (and ta to others too).

Shouldn't?

Yup... washed my hands earlier, now I can't do a thing with them!

In the case of contact with the live it would trip a breaker or blow a
fuse, but contact with the neutral could cause a number of more subtle
problems like nuisance tripping of a RCD.

The electrical book in the school library said it was a Good Thing that
the earth was uninsulated, as it gave the maximum opportunity for such a
fault which would be cleared by the fuses (one on each pole, in a little
wooden box)

Bet you dared not ask for more at lunch time either!

Not when these were done. On one occasion the owner was standing at the
foot of the ladders when I opened the cover and saw this.
"I did that myself," he informed me proudly.
"Looks like it, too," I replied.
