Hi,
I've been swapping some light switches and light fittings recently and being an older house, late 70's I think.
I found the lighting circuit runs off this wire, this being the live to all the switches, with an accompanying sheathed (red or black depending if its from the switch to light or the light to another light) and earth running along inside it.
The sockets run off twin and earth. So i'm wondering if this was the normal setup back in the day and what would you call this type of wiring with the live being separate.
Seems weird to me not to just use twin and earth for the lot unless 1.5mm didn't exist.
Thanks
