Induction Hob Install

potsy11

Hi All, I am just looking for some advice.

House was built in 2006. I currently have a gas 5 ring hob and I am looking to replace it with an induction hob. The hob has a connected load of 7.4kw.

It will need to be wired in. I have the usual (complete amateur) red switch for the over, my question is will this be suitable for the induction hob load or will it trip the switch?

Obviously not looking to do it my self and will get someone qualified, but before I go down that route, any advice?

Thanks

You need to know both the breaker and wire size the oven is currently running off. It is often standard to install much heavier wire than needed to run just a single oven which gives plenty of surplus capacity.

If it turns out they originally went for minimal wire spec you can still probably install a plug in induction hob which doesn't offer the boost function in the full spec induction hobs.

So you really need to know what you have already before asking. Alternatively you can get a dedicated line laid in but this will undoubtedly cost more than the hob itself.

I just checked the circuit board and the cooker has a 32A breaker.

The existing single oven is wired in with a thick (rectangular shape) grey wire. Is that of any help?

That's a 7.5kw feed so you can run your hob off of it but will overload it if you use your oven simultaneously. As I said you can get a plug in induction hob which will only draw 13amp at full load which would be ok. It should still be fine for everyday use.

Should be fine as is, when a conservative diversity calc is applied.

Check what the oven manufacturer says about required overcurrent protection. 32A may be too high and you may require a fused connection unit for this.

Unlikely to trip in normal use, but it might just trip when you're making the Christmas dinner with all four rings on the go as well as the oven.
