Okay, I have read everything I can find on this site about installing an electric shower, but have found some of the advice a bit confusing.
We have just finished renovating a two bed terrace which is now being let out to 3 students, and one of the improvements we have made is putting in an electric shower. The shower is 9.5kw, wired in 6mm (I can hear the groans already..!) via a DP pull cord switch and is less than 10metres from the CU. All the wire is tacked to the joists (none of it in trunking) and well away from other house wiring, central heating pipes etc. It is protected by a RCD and a 50amp MCB. The manufacturer recommended 6mm (yeah, I know!) so this is what we used.
So, my question is, what is the worst thing that could happen, given all the above? Is the wiring likely to melt? Is the MCB rating too high? Will the shower just pack in altogether/the RCD/MCB keep tripping? Should I take up knitting??
Any advice will be most welcome...except.....anything including the words 'ten' and 'mill'...
