Neff Oven

I hope to buy a new induction hob in the sales and I've been looking at a Which? Best Buy the Neff T40B30X2, however, some of the reports have thrown me a little. A Which? member commented

Neff and Which need to consider on how to install this product correctly from an electrical point of view. Electricians looking at the supposed power rating of this hob would probably suggest a separate 6mm twin/earth cable be used - however the product comes supplied with a 13A plug fitted on the flying lead. Running four rings on full power will exceed 13 amps - what is the answer? If there is some power management circuitry within the hob then Neff/Which should explain this fully in handbooks/reviews. When somebody finds out the answer let me know !!

When I look at the Neff website the hob doesn't seem to be there but there is a similar one Neff T40B31X2. However when I pop over to the likes of John Lewis they seem to be selling the Neff T40B30x2 The only think I can think of is that the 30 model has been withdrawn and been replaced by the 31 model. But this 13A plug thingy is putting me off. Is the guy on the Which? website right? I'm sure it is not a safety issue but will a 13AMP fuse let me run all the rings at once.

Another Which? member wrote:

...Regarding the electrical issue, after the comments above and debate elsewhere on the internet about these NEFF induction hobs, I finally found the answer. If the hob comes fitted with a typical (13A) UK plug, that's all it needs. The clever technology will never take the total power over, even if all 4 rings are on maximum. If however the hob comes with three bare wire ends, it should be hardwired into its own dedicated circuit, in exactly the same way as most other electric hobs, ovens, et seq...

I've been in contact with Neff asking about this but am still awaiting their reply. Can someone help me understand in simple English what all this means?

I think the second quote gives the answer you need, but to repeat: if it comes with a 13A plug then just plug it in and away you go; if it doesn't then it will need to be wired in by a qualified electrician.

Always refer to the manufacturers instructions.

The specs rate one of your links at...Total load rating (kW) Information 4.6kW

I'd be looking at a radial supply for that alone.

I have the big 5 'ring' Neff T44T90 which the detailed technical spec states the 'total connected electrical load(W) is 10,800(10.8kW)


The same spec shows the individual rings are 2.6kWh, 2.6kWh, 1.8kWh, 3.3kWh and 4,4kWh.(that total is 14.7kWh) Please note kWh for individual rings and Watts for the total. I assume that the 'kWh' is a printing error?
Obviously that had to be wired in, and is not on a 13 amp plug.


Those maximum power outputs for individual 'rings are when they are switched to 'Boost'. The rings are placed in 3 groups of 2 rings, 2 rings and 1 ring. There is a management system that only allows 'boost' on 1 ring in a group if that is the only ring operating at any level in the group.


So in the group with the 2 x 2.6kW rings one can be on boost only if the other ring is off(both can operate together in their non-boost mode)


So I assume a similar arrangement applies to the OP's choice of hob. i.e whilst the total load for all rings will in theory exceed 13 amps(a nominal 3kW) that is using the 'Boost' function on all rings. In practice the power management will not allow this to happen.


In any case I hardly think a firm like Neff would supply a product with a 13 amp plug if that couldn't cope with maximum load.

Any advice on what kind of Hood I shoul opt for.

The hob will be beside an outside wall. It looks as though my oven and hob will be Neff so I wonder if the Neff D2654X0GB Integrated Hood would do or do I need another kind

Go for the quietest one you can find. That one is noisy.

I have heard of induction hobs coming with power management circuitry that limits the load depending on the type of installation. Think about it though - a 13A limit only equates to about 3kw so if you have a big ring going at full pelt that leaves nothing for the others without seriously reducing power on the big ring.

This is just my opinion but I suspect performance will be unsatisfactory when loading the hob heavily and when running off a 13 amp supply.
