Yes I know that. 50 years experience!
My statement was about the fact that the earth wire in T&E was not already sheathed.

Reduces manufacturing costs!

I have heard many reasons for not insulating the cpc (only the outer part is technically a sheath), and some believe that if you have an exposed cpc, it will provide better protection to the cable itself, should the insulation on a live conductor become damaged. Personally, I think it's the cost factor

If it was insulated, it would not slice through the sheathing as nicely when making off :tounge_smile:

How was that worked out?
Damaged current carrying cable ie break in insultion, bare cpc, short between earth a live potentially.
