Hi there, We are planning to get a new kitchen installed in the next couple of months and have a question regarding electrics for 2 single ovens. We are getting Neff N70 range ovens one is a standard single one 3460kw and the other one will be a combined microwave / oven 3600kw. There is my question: we have separate ring for ovens only, and the electrician installed 6mm wire on 32A mfb with an isolator. I'm concerned if just over 7k kw output will be fine and safe to use both ovens at same time ? There was planned to have 1 double oven but plans have changed, cable upgrade is out of the question. Appreciate any answer of experienced electrician
1 x 6mm will be fine. Edit, sorry didn't read properly you cant put the ovens a ring but you can put them both on the 6mm with 32 amp mcb.
Sorry for misinterpretation. If I’m right current for both will be just over 29A + somebody mentioned that isolator take another 5 Amp ?
You can allow for diversity. Go onto YouTube and watch, John ward cooker diversity, he explains it better than I could.
"We are getting Neff N70 range ovens one is a standard single one 3460kw and the other one will be a combined microwave / oven 3600kw" 3460 + 3600 = 7060 divided by 230 = 30.69 amps So there is no problem at all without even having to consider diversity.
Yes the happy builders right but with diversity it's even less. 3460+3600= 7060÷ 230=30.6 30.6 - 10= 20.6 -70%=6.2 +10 =16.2. +5 if you have a socket on the switch=21.2 amps total.
Why are you putting a cooker control unit with a socket outlet, plug the appliances into the ring or radial socket outlets.
I thought the same, I think he means plug your appliances (kettle etc) into the ring/radial sockets so no need for a socket on the cooker switch.
Sorry my fault there is no socket on isolator switch. Much appreciate all answers. I will edit first post as there is no ring, it’s direct feed from mfb
