Hi All
Of late I've done a fair amount of electrical work. Just replacing sockets, switches & light fittings (all within part p in case the safety police are listening).
I know that the earth wire on T&E should be sleeved with the green/yellow sleeving - although I've found a surprising number of installations where it was missing.
Because I know it should be there according to 'regs' I've always fitted it.
But what's the purpose? Identification? Insulation? Protection?
Wouldn't all of these functions be better served by insulating it (like the live & neutral) in the first place?
In short, why is the earth in flexible already insulated, but left as a bare cable in T&E?
Doesn't seem to make sense to me.
