Built under oven and elec hob replacing freestanding cooker

[Cenci]

I have searched through a few threads but just wanted clarification

I have brought A SamsungPKG100 single oven with maximum output rating of 3400W and C61R2AEE hob which has 2 burners with an output of 1.8kW and 2 burners with an output of 1.2kW.

Currently replacing kitchen with freestanding cooker which is hardwired to a cooker circuit.

My question is can I wire both the oven and hob to this one connection? There is a socket near it which is in the cooker circuit but I read somewhere you can't wire a plug to oven over 3kw. Should I change it to a FCu or wire both to the old connection?

Thanks

My question is can I wire both the oven and hob to this one connection?

Yes, but use 4mm² flex for both the hob and the oven -
Assuming it is a 'normal' cooker circuit of 6mm² cable and 30A fuse or 32A mcb.

There is a socket near it which is in the cooker circuit but I read somewhere you can't wire a plug to oven over 3kw. Should I change it to a FCu

No, that would work out the same.
It's because the oven is more than 13A (the fuse in plug or FCU)

or wire both to the old connection?

Yes.

That's brilliant just as I thought cheers for the response. Didn't think FCu is an option, will just wore both hob and oven into same old connection (which is on sufficient cooker circuit rating)

Just so I'm clear the 4mm2 wire, does that have to be of a particular rating and Can I get from screwfix/bNq etc?

Cheers

Sort of - it is rated at 35A (i.e. more than the 32A mcb)

Can I get from screwfix/bNq etc?

I don't think Screwfix will have it.

You only need two x 2 metres so B&Q may do it.

That's what I should say but most people just use Twin and Earth.

They'll have that.

Only large reels at Screwfix.

Buy on-line if you have time or
local electrical places.

Will probably buy the wire from your link to be safe. Not fitting till next week so can buy a few meters online.

Really appreciate the advice.

last question.
manual says h05ss-f (180degree c) cable required (for hob)

can i use 4mm flex (from the link) ok as it was the one i was going to buy for the oven flex?

http://www.ebay.co.uk/itm/H07RN-F-3...al_Components_Supplies_ET&hash=item460dc5af59

its a lower temp rating but cant find stockists of the recommened

if i use the 4mm off ebay its surely better than twin and e what some people use anyway ?

Possibly for very good reasons.

I would so not use a cable with a lower temperature rating than specified the maker of the very hot thing it supplies.

but cant find stockists of the recommened

That's very high.

Neither can I.

The H07RN is rated lower for current so not suitable - unless you get 6mm².

So I'm good buying 4 meters of your original email link?

Manual for hob says 4-6mm
For oven says 1.5-2.5mm

I'll buy from the link you sent me and fix both appliances to same socket?

Yes.

You need larger for oven because it is on 32A circuit.

Same connector, yes.

I have only just noticed BAS's post.

The link to cable does not show any 4mm² which, if not used, would mean different wiring arrangements.

I appreciate MIs but have not before come across such a high temperature requirement.

 

[Cenci]

So we're going to stick to the original plan for your 4mm for both oven and job?

 

[EFLImpudence]

I didn't think there was ever any other.

The only problem is the temperature rating of the cable.

 

[Cenci]

Surely that's an overkill by the manufacturer?

Most people would just refit with twin and earth!
