Alot of cheap drill sets (300 pieces for 19.99) have the very thing you're looking for in them.

You'd think there would be a 1:1 scale printed credit card sized reference card that had all sizes on it, singles with & without insulation, and T&E you could just hold up to the cable and get a simple identifiable size comparison. If there is such a thing, where can I get one, if there isn't Copyright ME! You heard it here first!

That'll be the piece of cardboard with samples of the cables sellotaped to it.

If it was built before the early to mid 80's it will probably be 2.5/1.0. A lot of PIR's I do have 2.5/1.0

or it might just be stranded imperial cable . best left alone as it's better than anything available now to replace it.

Probably got more copper in it too

did a pre CU change inspection the other day. client was concerned he might need a rewire. all circuits in 7/029 power. 3/029 lighting. IR tests fine. as good as the day it was installed 45-50 years ago. told him if it was rewired in modern metric crap, it would be no better or even worse than if left.

Im sure the cable I bought last week was padded out with sawdust, connective tissue & injected water
