I intend to replace my existing electric shower ( 8.5kw ) with another of the same rating. The present installation uses 6mm cable running 8 metres. The cable is protected by a 32amp MCB.
As I am simply changing the shower unit only, will this installation still meet all regs?
If it is inadvisable to keep this installation will the following be correct for an 8.5kw shower.
8 metres of 10mm cable protected by a 40amp RCBO at the CU ( main switch 100A ) Wired to a wall mounted 45amp DP Switch located outside of the bathroom.
I know that a new installation will need to be done by a qualified sparky but I need to at least route the cable and do other prep work beforehand.
