UK Hardwiring an induction hob

[Santa]

I already have a 3kw double oven hardwired with 6mm twin and earth, direct to the consumer unit. Can I also add a 2.7kw hob to the same circuit?

Alternatively, can the hob be hardwired to the kitchen circuit?

It should be fine if it's just the double oven and hob with no socket outlet on a 32amp breaker.

Great - thanks.

I just realised that the hob power is 7,400 watts. Does that make a difference?

I wouldnt wire the hob direct to kitchen circuit even if it comes with a plug as the regs advises against this but its rather vague ,just states cookers ,hobs and ovens should be on its own dedicated circuit unless less than 2 kw .its just trying to reduce the amount of load through your sockets.if it was a portable 2.9 kw hob then you could plug it in anywhere so it's not very clear in my opinion although I have stuck to it as good practice.you are allowed to apply diversity to your cooker circuit as the elements switch on and off at different times frequently

so the total load of both can be reduced by using the following method
The first 10 amps of total load then 30 percent of remaining load and if you have a cooker switch with a socket you need to add a further 5 amps onto this.but because it's 2 seperate appliances as appose to one unit it needs to be applied separately to both units but the difference is minimal due to the small loads involved.so you could easily add the hob to your oven circuit but I would refer to the manual of hob and see what requirements it needs for over current protection ie mcb or 13 amp fuse.without knowing how cable is run in ie glass wool etc and size of mcb for oven I would guess the 6mm twin and earth will be absolutely fine to run both but you would need to get an electrician in to link them to same outlet as there would be a bit of alterations required .check your mcb if it is only a 16 amp it would be no use it would ideally be a 32 amp .your total wattage for both appliances is fairly small as most hobs are far greater than 2.7kw ,more like 5 kw but you would need it checked out by an electrician

Yeh that would def don't take it of sockets lol.you could possibly still be ok .the diversity could still be ok but the size of breaker would need to stay at 32 amps unless you know exactly how cable is run through the fabric of your house.it could be buried in 3 feet of glass wool or be a particularly long run

How did it go from 2.7 to 7.4kW?

The 7.4 is the absolute maximum…. For hobs, we apply diversity as not all 4 rings will be on at the same time.

Is this an induction hob ?
What does the manufacture say ?

Also some ovens will give the total load but that can never be reached as you can't have the grill and oven on at same time but would depend on model .mine is 3.4 kw but using clamp metre dosnt get anywhere near that regardless of what setting its on
