when was imperial cable last in use?

I think imperial cables were last made about 1970. When I started in 76 it was all metric and had been for a while.

Ok Thanks, When was the rubber insulated stuff last used?

Rubber disappeared a bit earlier, you can get imperial PVC cables but no metric rubber as far as I know.
The give away is the conductors, tinned and stranded = imperial, solid with no tin = metric.
You also got Imperial PVC twin with no earth.

It was about the same time as decimalisation.1970

Whats powering the LHS RCD?

Was wondering the same - no sign of a cable into the RCD (or it has a painful bend radius we can't see).
