Why cover earth wire?

[Ziggie]

for T@E cable, we cover the bare earth wire with a sleeve of green / yellow. Why?
The basic idea is that if there is a fault then the live wire meets with the earth and covering the wire with insulation potentially stops this action in some cases. Is it not better to have the bare wire to increase the chance of making contact with a live?

I realise that it makes it easy to identify, but all other cables have coloured sleeves.

This is common in Ireland.

I remember working a site in the UK in the late 80s early 90s can't remember exactly but we installed a load of 1.5 with sleeved cpc, didn't take much notice at the time but all other sizes had bare cpcs.

It wasn't in the 90s.

but there is an argument in favour of least use of the Earth's resources which the RFC and T&E construction were originally driven by.

If so, then that is very noble.
