Shower 8.5 on a 40mcb is it dangerous

[chrismoy1]

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

Tell him to have a look in Appendix F of his on site guide and get back to you.

Is this guy definitely and electrician and not just an appliance installation guy from a electrical appliance retailer?

Definitely says he is an electrician, his web site says he does all types of work not just domestic, but industrial and commercial.
States part P and nicec approved.

Well even on here, we have our disagreements. As we are not actually 'on site', why not seek an opinion of another electrician to go & have a looksee.

Ok, I have had some run ins with Currys installation guys before telling the customer something is unsafe when it is perfectly fine, wondered if that was the case here.

Giving they guy the benefit of the doubt.

I can only assume the cable run is concealed so he is assuming the cable is covered in thermal insulation and adjusting the current carrying capacity accordingly.

Why he would make that assumption and proceed to tell the tenant it is unsafe, whilst attending to connect a cooker, is another question in itself.

Either that or he isn't aware that CCC is dependant on the conditions in which the cable is run, and he should know better.

To be fair, most (electricians) might think (off the top of ones head),
6mm = 32A supply
10mm = 40/45A supply.

Perhaps the 'its dangerous' was an off the cuff remark, without thinking of 4 pages (soon to be 5) of consequences on a thread on an electrical forum.

No way he will cover your area, there may be a member who will cast his eyes over the thread who is though.

I think its no secret that sparkies like to slag each other off , and this place exasperates that quite a bit I suppose. Its very easy for it to turn into a circle jerk when the guy in question is not here to defend himself.

Really? So most electricians are wrong. Does not give one confidence.

4 mm 32 amp supply.
6mm 40 amp supply.
10 mm used to supply a whole house.

Well there is no such thing as part P approved, so that is another thing he has got wrong.

Part P is a building regulation, that is all.

Yours are least case scenario, 'mine's' applying worse case scenario.
