Hi guys

My tenant just had an electrician in to connect her cooker and has told her that the shower is dangerous and not to use it because it has a 40 mcb in the consumer unit and it should be a 32.
The cable is 6mm and the shower is 8.5kw.

Can you advise me please
Thank you in anticipation
 
I do actually have a certificate of approval from NAPIT that states I am approved for electrical installation work in dwellings (A1.1) (Including Part P).

So it could be argued that I am 'Part P Approved' or 'Part P Certified'.

But again, I think most people understand that when someone says this, what that translates to is 'They are members of a competent persons scheme and are able to notify works in accordance with Approved Document P'... it's just easier to say Part P certified, of Part P approved or something akin to that.

I have exactly the same in my house, since upgrading my shower 7 years ago, with no problems, and will be fitting another to the same specification soon. One factor no-one has mentioned is circuit length. I believe a maximum of 10m (33') before a larger cable is required. If voltage at supply is greater than 230v (it usually is), longer could be used. I would verify voltage drop and RCD trip time to be sure.
 
Chris, this is the correct sized MCB for a 8.5kW shower, a 32amp device would be running at a slight overcurrent and although it would take a long time to trip it's not permitted in the regulations. I can't stand people who find fault with work unrelated to what they're doing - especially when they're spouting BS. :)
I confess that finding faults in electrical installations has been a favourite pass-time of mine for over 30 years! I agree entirely with the BS though: I've heard some lame excuses, and had my work criticised by many who should know better. It is a nuisance having to explain or pull out the Regs to show them. I try to always be open to constructive criticism, but no-one needs the BS, and I don't need the opinion of someone who born 20 years after I started working!

As an update I have now had a full inspection done took 4 hours and everything passed OK. thanks for all the replies.
