Replace a ceramic hob with an induction hob

Hi there, Your old job is rated at 29amps and your new one is rated at 31.5 amps. As long at the cable supplying your existing is 6mm and protected by a 32amp MCB (fuse) it should be a straight swap. The jobs are normally held in place by 8 clamps that can be accessed by the underside and would be fairly easy to swap over. But, you really should have an electrician carry out the electrical connections just to be on the safe side. Hope this helps

New is 17 A old one is 16.3 A. As long as there is no sign of thermal damage then simply swap out. Above figures use diversity.

In accordance with BS7671 you apply Diversity to Hob's & Oven's Table A2 BS7671 On Suite Guide BS7671 Regulation 536.4.202 The old hob will have a diversity factor taken into accout and will be around 15.73 Amps The new Hob will also have a diversity factor taken into account and will be around 16.52 Amps Provided your cable is adequate (6.0mm being the norm) which i'm sure it is and there is no signs of termal damage it should be fine for a straight swap. Though i would recommend you get an Electrician in to do it safely.

Like all jobs this can by done by someone who is competent. The issues to look out for are 1. Is the new unit exactly the same size as the old Unit, if not you may need to adjust the cut out. Most of these are fitted tight and a small difference making it fractionally too small with too much pressure can break a ceramic hob. 2. I suspect the cable you refer to is twin and earth. You need to refer to the manufacturer instructions as some require heat resistant cable (flexible) of a particular size. 3. The manufacturer normally specifies the fuse size but 32 amps would protect the cable. Best wishes This is not notifiable work nor does it require any form of certification.
