Lowering existing electrical socket

[diynot]

Looks to me like UNG suggests.
The left hand cpc goes over to the right with a short piece of sleeving. Both are then twisted together, and use the same sleeving up to socket.
You can see two cores twisted together at the terminal.

When you re terminate lower, you should have the docs in separate sleeving, and not twisted at all.

Ok thanks. Seperate sleeving is easy, don't know why this wasn't done years ago when originally fixed. Thanks.

Because the integrity of the earth wire is the most important of all, and when the installation was done, twisting the wires together was seen as a better way of ensuring this than relying on a terminal clamp in the fitting.
There was no requirement back then for a lot of the testing that is required now.

Right, thanks for the explanation.
