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

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.

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?
