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
If we always add sleeving, and I think we pretty much always do, it rather begs the question why we do not do as other countries and allow cables with insulation in the earth core already - as made for ~Ireland for example
Or TPS for Australia
If it existed, I for one would be inclined to specify it.
