UK Hi everyone, new to the Forum, no electrical knowledge

Hello everyone, I'm a new homeowner member and would be really grateful for some advice as I know virtually nothing about electrics. My question/worry involves two single ovens I've just had fitted that the electrician has plugged into a double socket. There is also an isolation switch fitted in the cupboard. I have read that a double socket is good for 20 amps, these two ovens are 2.85kw each and are fitted with 13 amp plugs. Doesn't this add up to 26 amps being used if both ovens are on at the same time? Isn't that a potential fire hazard? Previously in the same place was a slot in double oven cooker wired in with a thick cable. I have also had an induction hob fitted and that has been wired in. I have mentioned my worries to the electrician who tried to explain things to me (went over my head) and ultimately said a double socket is fine. But I'm still unsure and it's niggling me.

I've attached a photo. Any help would be appreciated. Thankyou

Are you saying that there's an electric hob on this circuit as well as the two ovens??

Yep. Until the new electrician can put everything right I'm only going to use one of the ovens and go steady with the hob

Gas hob or electric hob? I thought I saw some reference to a igniter (for a gas hob) earlier in the thread.
If it is an electric hob, a 32A circuit is definitely overloaded, and at least one of the ovens needs its own dedicated supply from the CU, or the whole lot needs upgrading to a 40A or more circuit. Sounds like your new sparky might know what he's doing.

Yes it's an electric hob. I feel relieved that the new electrician is putting in another supply. ?

Is this an induction hob, as they need a substantial supply compared to a halogen hob, make sure the wattage rating of the hob and cable match.

Yes it is an induction hob. I will check wattage ratings match, thankyou

Not necessarily. Some have software that makes sure the total current drawn at any instant is kept down to sensible levels.

And that would be shown by the wattage rating of the hob as I said above plus these are in the main the induction hobs that have a 13amp plug fitted they are also normally a replacement hob for a halogen or similar hob and a compromise, a normal induction hob has a rating that will require a dedicated circuit, in fact the one I have runs off two phase's of a three phase supply.
