im in the process of renovating a chip shop. im not actually doing the electrics at the moment but i am about to take the job on if it comes to it. The electrician on the job has put both a lighting circuit and a power/socket circuit in the same 32Amp MCB. ive have told him that is wrong and dangerous - but he persists that it is correct. Can anybody verify my opinion? If I am correct, which I am sure I am, what is my next step? shall i take the job and change the problem? Shall I notify the NEC as this electrician is supposed to be a tester and issue certificates? Or should I leave him to it which is a danger to those using the appliances? I would like alot of feedback please because I will be using these replies in a site meeting to try and correct the problem.

Thanks
Adam
