Induction hob and electric oven running from same 32 questions... Again

[Howard Thomason]

HI Guys, so looking for some advice I've had a re-wire for our new kitchen all was going to plan until yesterday when I realised that my changing of appliance could be a issue.. I told the electrician I was getting a range style cooker so he wired up for this, I changed my mind after seeing the prices and carried on plodding away fitting the kitchen, with what would be a ikea induction hob 6. 5 kw no cable included. And Ikea oven 2.48 kw, I have absolutely no electric knowledge and my electrical is on holiday he is due back in 10 days to fit sockets etc.

IS it possible and safe to run these from the same 32 amp fuse? the consumer unit is directly right by the dividing wall very close. It looks like a 10 mm cable, as far as I'm aware he has prepped for a cooker switch on the wall and incoming range power cable at just above floor level, there is also a separate white cable that runs above for an extraction fan as pictured tho it looks like it may be run from the 32 also. I've attached lots of pics hopefully someone can help me out I'm confused as I have seen lots of posts saying it's fine but others saying it nerds separate fuses. Cheers guys

Yes, 32A will be more than adequate.
He/you will need a dual appliance connector if both appliances wire in.

If the oven is on a plug, he will need to add a 13A socket. This can be wired from the cooker connection point/

Thanks for the reply, thats good news, both the cooker and hob state hard wiring, would i be safe to carry on tiling or would the dual connection result in the walls needing to be hacked away?

TBH the best thing for you to call the spark and ask him to pop in ....

I think you should wait until you electrician comes back, before proceeding any further. Not sure why the supply for your cooking appliance, whatever it might have been, is behind said appliance, and is that a round flexible cable used to supply the fan?

My reply remains as stated in #2

That's the technical bit answered, just the practical things that need a referral

which picture shows the existing oven cable?

 

[Midwest]

Think its the one with the level in it?

 

[Midwest]

Are you thinking what I'm thinking?

PS I think my observations about the white flex is incorrect, looks like a bit of flat cable?

 

[Howard Thomason]

thanks for all the feedback, the consumer unit is located safely in the hallway its just worked out well that the new housing unit for hob/oven is located next to the wall dividing the hall and kitchen.

there was no existing oven cable, as its a new layout all oulets/cable you can see pictured are new.

i have no idea what type of cable is being used for the extractor although it is definitely a white outer sleeve there is as pictured some other wires that i believe are to be used as a isolation switch for the extractor https://photos.app.goo.gl/KNsEz6jf1piYJbTk9

So is that twin metal back box (& cable) with the level in front of it, the new supply for your cooking appliance?

I presumed so... for the range that was planned .however this was a single box that i changed to a double in anticipation of both hob and oven having plugs and thought it might be helpful to the electrician, Then i woke up!! and it dawned on me i know sod all.

I assure you i had a qualified electrician give my kitchen a full re wire he is due to return in 10 days after his holls to fix in my appliances and plates/ lightes ect. i have no reason to lie about this.

I am just asking for advice, However i am now concerned regards to the workmanship due to your comment, can you see something that is not within regs or unsafe??

Placement of a cooker connection unit behind a built-in unit can be problematic, especially a dual outlet one, because of the limited space behind built-in appliances.

It is also normal to provide a means of isolation adjacent to a cooking appliance(s) & above worktop, although you say the CU is close by, and some would say that is sufficient, i.e. using the circuit MCB as means of isolation.

It is easy to criticise someone else's work, however the pics you've shared show a slight lack of good workmanship, as above.

Thank you, i think i can explain this.... the cooker connection ( bottom double on pics) was not intended for a built in hob/oven as stated in my initial post the electrician wired up for a range cooker( the electrician left presuming this was happening) , I then changed my mind and decided to get induction hob and built in single oven and fit them in to a housing where the range was going to go.i really did not anticipate this being a problem.https://photos.app.goo.gl/Yn6mbqEzyRj3Wbpm9

as for the isolation above the worktop there is one this can be seen in this pic at the moment it has no plate and looks like its light switch height. https://photos.app.goo.gl/onY4Dxo698vFGUJC2

so is the metal plate you can see behind the housing dangerous?

Arrgh ok I see.

You'll see from Taylors #2, the dual outlet plate is fixed to a single back box not a twin. The outlet plate needs to be mounted higher up, to ensure the flex's to the appliances aren't bent and damaged by the shelf (normally about 150mm). You may struggle fitting said plate behind your built-in appliance, because of the space taken up by the appliance and depth of plate, measure it & verify.

As said before, I would not progress any further with your kitchen, and await the return of your electrician.

Indeed. So you must wait for your electrician. To begin with, to fit two accessories in the same box you need a DUAL box, not a double!
Secondly, you don’t know even how the oven connects. Does it have a plug? If so you need a socket and a CCU from the 32A circuit.
Thirdly, what’s the plan re the extractor?

Too many questions, and you don’t have a scooby. I know you feel guilty because you changed your mind, but you’ll have to be patient. You’ll only add to the work he’s got to do when/if he gets back from Hawaii.
See if you can get a bulk deal with Deliveroo while you wait.

IMHO all fixed appliances, on shared RCD's should ALWAYS have accessible means of DP isolation.............
