Hi All, i'm pretty new to this forum and hope this is posted in the correct section.
We're having our kitchen refurbished and wanted some advice on what wiring we require. The kitchen company have put a rough spec but nothing telling me what I require. I will be getting someone to do the work but wanted a rough idea on what I need to be asking for and what breakers I need to buy for my existing consumer unit.
We're having 3 stand alone ovens (yes the wife likes to cook!) and a microwave. The ovens are all rated at 3.5Kw each. The run to the ovens is 10meters (7m clipped, then 3m through a uninsulated ceiling void) So I thought these would require 4mm2 and 20amp mcb each? Or is this over doing it, and could it be done on 2.5mm2 on 16amp mcb?
The kitchen isn't currently on it's own ring main - so I wanted this putting on it's own - so obviously 2.5mm2 on a 32mcb. A built in microwave, boiling tap and dishwasher will be on this circuit.
Then there is the induction hob which i'm struggling with. This is rated at 11kw. The run to the hob is 14meters (7m clipped, then 7m through a uninsulated ceiling void and down a uninsulated stud). I thought this would require 10mm2. The manufacture recommends a 50a fuse, however wouldn't this be pushing it on a 10mm cable? I thought a 45amp would be better however one isn't available. So the question is that, is 10mm2 enough and would a 40amp breaker do the job?
Thanks.
