0.5mm T&E cable now available.

I lived and worked in London in the late 70's to the early 90's and 1mm was readily available in every wholesaler, I always preferred the white T&E for surface work. That is fact

The only times I saw it were hidden over kitchen cuboards for downlighters, hidden lights, etc, white as well. But most I saw was flex in those situations. Never saw 1.00mm grey T&E in a 1st fix. Never. I do now.

You need to understand opinion and factual observations.

If I am installing for want of better words a simple circuit I know what cable size is required and have no need for calculations this is not rule of thumb it is experience knowing if I had calculated it I would have the same result.

It was rule of thumb you were using.

IMO 1.5mm T&E is a waste of copper for lighting circuits, especially now with LED's.

No it was experience there is no rule of thumb.

I get the sense that this is intentionally being drawn out by the OP for the sake of it.

I am not the one being objectionable. As I have written, my experinces appear to be 100% the opposite to many here.

Very rough rule of thumb for sizing cables is that for lengths up to 50m the current carrying capacity is all you need to consider. Above 50m other considerations come into play.

I was using 1mm T&E in 1979

1980 for me

School was just letting me loose on crayons in 1980, but the colours hadn't been harmonised.
