At the moment I have a stand alone cooker – it is an electric oven with gas hobs.

I want to get rid of this and extend my kitchen worktop to put a new ‘built in’ electric oven underneath in a new oven cabinet and a surface mounted electric Induction Hob on top. (I shall be getting a Gas Safe Engineer out to disconnect the gas part of the cooker and cap off the gas feed.)

With the current electrical set up, I only have one power feed cable from my distribution board/box (which is in another room - hallway 10m away). I have been told that this is a 6mm2 Twin and Earth cable and runs from a 32A MCB in the distribution board/box over to a 45A Cooker switch on the kitchen wall. The cable then runs directly down to a single power output connection plate where the existing cooker connects into.

The new built in oven I want to get has an electrical connection rating of 3,450W (the spec also says Current 16A and Voltage 220-240V) and the Hob has an electrical connection rating of 7,400W (the spec says Current 32A and Voltage 220-240V). These are two separate units.

My logic says that putting the two together would mean an electrical connection rating of 10,850W with a Current requirement of 48A but I don’t think it actually works like that with the current rating, and this is where I am lost.

Before I ask an electrician to come out and give me quote for the work:-

Would I be able to use this existing cable and changing the existing single output plate to a 45A Dual Appliance Connection Plate so that both the Oven and Hob can be connected up to the same cable/cooker circuit? (i.e. the existing 6mm2 cable with the 45A Cooker Switch and 32A MCB)

Another option would be to run a second 6mm2 power cable over to a new 45A switch recessed in the kitchen wall and then running down to a new 45A single output plate for the Hob to connect into. This would mean that I have two 6mm2 cables, two 45A switches and two output plates – one for the Hob and one for the Cooker. Or would I need another cable?

The problem with this is that I don’t have any more spare positions on the distribution board/box for a new MCB trip fuse which would mean a new larger consumer unit and complete re-wiring. Also I don’t know which way the existing cable runs (up into the ceiling, or down into the floor). Either way I would need to dig up the laminate floor or break into the ceiling which is all very costly.

The last option is to get an Induction Hob that will run off a 13A socket, which is available, but I have heard that you cannot run all hobs on full power at the same time (i.e. they all run at about 50%)

I would really like to do the first method if possible and have both running off the same dual feed.

Can anyone help me on this?
 
Thanks to all your replies. The first few seemed quite positive and I was feeling optimistic about not having to run a new cable, but the last ones are making me doubt it.


I haven't decided who will do the work yet but the NICEIC qualified electrician will be independent to any kitchen fitters as I need to have the gas cooker removed first of all and the gas supply capped off. I then want to have the built in oven and hob temporarily installed and connected so that I can still cook before the kitchen fitters come in. It sounds a long winded way to do it and it's a long story why, but the kitchen fitters don't do gas and it's too risky to try and coordinate all the removals and installations over a day or two with the other work I need to do beforehand as well!
The kitchen fitters will connect electrical appliances though so they will permanently re-connect the oven and hob when they do the kitchen.


I also haven't decided on the oven or hob yet so I don't know what the installation manual says although I might try and download the ones I am interested in.
NICEIC Qualified? now there's a thought:eek:

You might want to re-think that. All the kitchen refurbs' I've been involved in, the householder is temporarily 'banned' from the kitchen.

Generally the old kitchen is ripped out, electrics & plumbing done. Plastering, drying time. Decoration, then new kitchen installed. If you beg my pardon, you farting around in that process cooking dinner, is not going to go down well and will delay things.

Live on microwave meals, takeaways or go down the pub for your evening meal. ;)
Agree, nothing worse than having Mr and Mrs home owner hovering around when you are working, could be some friction involved.
 
^^ why "the NICEIC" electrician? Have you identified one? There are other schemes too....
Yes,why indeed Niceic
Its like wanting to buy a pot of jam,then restricting yourself to Sainsburys whilst Tesco may have Jam with better quality
Thank you for all your replies.
My knowledge about electricity principals and electrical work is very minimal hence why I am asking questions on this forum and I haven’t heard of any other regulating bodies apart from NICEIC so sorry if this sounds naive but what others exist? and would I get the same standard of certification for any work that was done to prove it was carried out to a safe standard?

NAPIT, STROMA, ECA, ELECSA oh sorry they are with NICEIC,
 
add up the 2 kilowatt ratings of the oven and hob. if it's <15kW then both can be fed from a single source. 6.0mm cable on a 32A breaker. job's a good 'un.
 
have to chuck one in now and then. life would be a drag otherwise.and a serious bit of thinking kickes the balls of that doctor alzeimer.
 
Just ask your friends and neighbours for recommendations That's how I get most of my work. And ask the sparks if they are registered, then make sure you get the Certs with the invoice
