Hopefully a quick cooker instal question

jonjay3012 · 22 Oct 2013

Hi, We've just had a new kitchen fitted and have a nice shiney hob and cooker to go in.

The hob is gas and has already been fitted, but needs the electrics plugging in for the ignition. The oven is a single electric fan oven.

We used to have the same configuration, gas hob and electric oven. Both of these were connected to a round input plate on the wall behind the oven, which was then wired with thick cable to the cooker switch above the worktop.

We have installed a new cooker switch (to include a 3pin plug on the side of it), but have not changed any of the wiring other than that.

The question is, is it safe for the new hob and oven to be wired in to the existing appliance input plate behind the oven, or should these be fused before they get back to the main cooker switch above the worktop.

Thanks for any help, and sorry for the non technical description.

Yes

or should these be fused before they get back to the main cooker switch above the worktop.

It is not possible to tell from here. What do the instructions state?

Did the oven come with a plug? If not use 4mm² flex.

The hob should probably have a fuse but if conditions are correct it may not be necessary.

You could fit sockets or fused outlets in addition to or instead of the cooker outlet.

Thanks for the quick reply.

The cooker outlet (assuming you mean the above counter cooker red switch) is wired back to the main fuse box with it's own circuit breaker.

The oven and hob both come with cabling attached, but neither had a plug fitted.

This is the manual for the oven,

I can't find a link to the hob manual but this is the hob

Thanks again

No, the outlet behind the oven.

The oven link doesn't work.
The appliances will have instructions included stating how they should be installed.

Sorry about the bad link

The user handbook on this page has the same wiring instructions as those for my hob

And this one for the oven

http://www.myspareparts.co.uk/cata/Cata-A3MULTI-built-in-single-electric-oven

Looking at the instructions in those, it seems as though both appliances will need 13am fuses, so cannot be connected in to the existing multi entry cooker outlet, as this is goes directly to the Cooker switch with no fusing between. My reading is that I will either need a 2 gang 3 pin socket under the worktop in place of the existing cooker outlet (but with the same wiring to the cooker switch) and plug both in to that, or 2 fused faceplates, one for each?

Again, thanks for taking the time to reply.

Yes.

Pity that, for the hob, you have to be a member of NICEIC to install it!

Is that right, just to connect the ignition on a gas hob, but you don't for the oven? The gas work has already been done, it's just a case of conecting up the electrics.

EFLImpudence · 22 Oct 2013

Didn't notice that.

jonjay3012 · 22 Oct 2013

Sorry EFL, didn't notice what? That you have to be registered to plaug in the hob?

Seems a strange one if it correct that you would be able to DIY the oven but not the hob, when they seem to be identical jobs.

EFLImpudence · 22 Oct 2013

No, it was just a comment on the requirement for a NICEIC member which is, of course, nonsense.

jonjay3012 · 22 Oct 2013

Excellent. Ta.

So, one last question then, although I think I know the answer. Would I be better off putting a double plug socket in and putting plugs on the appliances, or putting 2 13amp fused spurs.

I'm thinking the plug option would be far easier, assuming this could be surface mounted behind the oven, and have the cable from the Cooker switch running in to it.

It's up to you. It makes no difference electrically.

Yes but make sure there is room, of course.
A surface box plus the plug will be quite big.

If room is available there is nothing to stop you putting a surface mounted double socket in the cupboard next to your oven for easy access.

In this case, with one of the loads trivial, I agree that it makes no difference electrically.

However, more generally, does 26A vs (probably) 20A not represent a bit of an electrical difference?

Kind Regards, John
