Replacing 12v bathroom fan with 240v one.

Cool, but you need to measure the diameter and calculate the cross sectional area.

Here’s a photo of the cable.

That's 'twin and earth' cable, so will be fine for 230V/240V, whatever its size (the smallest available is 1mm² - which itself would be considerable overkill for your fan).

Kind Regards, John

Ah, ok. That I will do in the future. I may be an engineer but I’m no electrician! Anything more complex than this I would definitely pass over to skilled guy who knew things like that.

Looks like 1mm² twin & earth.
Fine for a 240v fan.

Thanks guys.

He said the earth wire was 1mm dia. That gives a CSA of 0.78 mm sq. Something not right.

I would presume that the "something" is measurement error and/or approximation - i.e. "1mm" is actually about 1.13mm.

Correct. When I thought that the diameter was the deciding factor, I rounded to the nearest 0.5mm increment and assumed manufacturing tolerances were the reason it wasn't quite a 1mm.
