UK Hardwiring an induction hob

[mainline]

Hope this helps!

The manufacturer states it should be installed by an electrician you just need to find one

The AEG DOUBLE OVEN Model Number is DEU73111 HOB IS AEG IKB64401F-B

I would get rid of the junction box and fit a dual outlet plate mainly because it’s better that a that junction box that’s thrown on the floor.

Proper flex instead of the twin and earth would be a better job.

Is that a fused spur on the left ?
I can’t tell from the pic

Yes I think so....Engineers/ Electrician stated if I had a new plug & play hob they would cut plg off & wire directly into 13amp wall fuse box? That leaves oven on its own in floor junction box. Other option was to have new circuit traced back to fuse box costing thousands

They certainly have NOT applied diversity, whatever their little report says.

Taking the diversity equation from earlier in this thread, (message #5)

For each appliance, work out total amps....

Hob
7300/230 = 32A
Take 10 off, and add 30% of remainder.... 30% of (32 - 10) = 6.6
Add the 10 back on... 16.6A

Oven
5300/230 = 23A
30% of (23-10) 3.9
Add the 10.... 13.9A

Total load with diversity is 16.6 + 13.9 = 30.5A

That's quite a conservative way of applying the diversity.
Taking the oven and hob as one 'cooker': 7300 + 5300 = 12600. Divide by 230 gives just under 55A
Take 10 off = 45A. 30% of 45A = 13.5A. Add the 10A back on gives a diversified total of 23.5A.

Either way you do the calculation, there's no reason why they both can't be connected to the existing supply.

Edit: Just read the specs, and it's 5900W for oven, not 5300W, so diversified load is just over 24A.

I took the diversity factor from #5, and from other threads about it, if its a combined load with 2 appliances, you take off 20A to begin with... ie 10A each.

What i didnt take into account was a possible socket on the cooker switch, which adds 5A to the final result.


Can we take care that we are replying to Snow White's enquiry from message #21, and not Santa's from the beginning.... different sizes of appliances.

It's Snow White that my post's aimed at.
In an ordinary domestic kitchen I see no reason to treat a 600mm hob fitted directly above an oven as anything other than a slot in cooker. With a large double oven, fitted into a taller unit than normal worktop height, I would gravitate towards your method.

Apologies to Snow White, this is a question aimed at other members of the forum - I don't think I'm understanding the first picture correctly.
In the pic, is the 60A junction box wired correctly? Apparently incoming power on the left.
All depends on how the other end is wired I guess!

I see what you mean, but if the circuit's RCD protected, it can't be. Could do with a better pic though.
