Hi,
Had to change a bathroom fan at the weekend for someone and they wanted it to be on a timer, but couldnt as the cable was buried in the wall and wouldn't move etc..
the cable that fed it was a three core flex, I the earth was not being used anyway due to the load on the end etc.
I know you are not meant to use the CPC as a live conductor, but if its flex and the same CSA and you were to correctly identify it with brown etc, would it have then been acceptable?
I didn't do it, but it made me think, oh i so could have used it, but it just seemed wrong. I can understand why you wouldn't do it in twin and earth, but surely where its flex or all conductors are the same CSA and have their own sheathing on them inside the outer, would it have been acceptable or not?
I am going to say not on the basis CPC is CPC and nothing else, any thoughts would been welcomed.
