As the title says.
Before 1966, most domestic lighting circuits were wired in 2 core cable without an earth wire.
I've seen properties older than that where 2 core+e was used as the feed cables, with 2 core only switch drop cables. This allowed for metal light fittings, and plastic light switches but with metal flush boxes with nylon lugs.
And also seen houses wired in just 2 core only cable, so no earth, with brass ceiling and wall lights.
Brass and other metal light fittings have been around about as long as electricity itself.
Many properties were wired in 2 core only rubber or PVC lighting cable and I'm certain metal light fittings were sometimes used - even seen pre 1966 places where an earth wire is present, but either cut off, or if you're lucky, the earth wires have been twisted together and simply pushed out of the way - but still not connected to a class 1 light.
So, my question again, was it ever acceptable not to earth metal light fittings?
