Induction hob?

[shawy101]

Hi,

I'm new so please be gentle.

I am just about to start the process of changing out my kitchen and I'm after some guidance with regards to changing my existing gas hob for an induction one.

Currently I have a double oven fed by a 6mm twin and earth rated at 4.4kw, as far as I can tell, running from the consumer unit on a 32A RCD. I have the power for the ignition on the gas hob running from a switch on the wall on the normal ring main for the kitchen.

As far as I can gather I have two options

1. Spur the power for the induction hob from the switch for the cooker (running both off the 32A on the consumer unit in effect)

2. get a lower powered induction hob that can run off a 13amp plug (I have reservations about this with regards power output, is it worth it)

is there anyone who can advise me on this, power limits for the induction hob if I were to spur it, if its safe to do so?

I cant run a dedicated power supply back to the consumer unit (its full) so if thats the only option I'll just have to stick with my gas hob.

Thanks in advance.

btw a little diagram

For almost all induction hobs, your plan 1 will be fine.

Use one of these dual appliance connectors to allow the existing oven and new hob to share the cooker outlet point.

You will need to use 6mm² cable between the dual plate and the induction hob, or the hob may have its own cable supplied.

I would tackle the job as TTC has wisely advised.

Thanks both of you. That's good news. Is there a maximum rating for the hob that I can use? I think most sit at around 7kw?

If we apply diversity to the hob and the oven as separate loads then you should be OK up to 8.5KW. That covers almost every domestic induction hob.

True, but is it not normal to apply diversity to the combined loads of all cooking appliances on a single circuit? If one does that (and assuming no socket supplied by the circuit), the hob could be something like 12.5 kW - certainly more than any domestic induction hob.

...and 4mm² cable would be sufficient.

Indeed, it probably would (depending on how it was installed), but I imagine most people would probably install at least 6mm².

Kind Regards, John

Thanks very much for the advice. Looks like i'll be going for the hob with the dual outlet plate and some 6mm between.

Sounds like a safe bet.
