Shower electrical cable
 

Hi,

I'm about to swap out the old bathroom suite and replace it all including
the rather nasty shower.

The shower is I believe an 8.5KW affair and the power supply appears to be
fairly modern (approx 2yrs old ) cable on a 45A breaker.

But, I can't tell what the size of the cable ie. 10mm^2, so I'm not sure if
we can have a more powerful shower without risk of overloading the cable. I
read somewhere that by measuring the outside diameter of the cable you could
determine the size of the conductors in the cable, anyone know of these
figures?

Cheers,

Jeff
