SCOTTISH ELECTRICIANS QUESTION

[Pablo1]

quick question, installing a new gas hob (3amp fused plug for ignition) and a single oven less than 3kw (comes with a 13amp fused plug attatched) .

Im pluging both into a double socket inside the built under oven housing,

DO I NEED TO ADD A SWITCH TO ISOLATE THIS SOCKET ABOVE THE WORKTOP ??

and you english can feck off with your part p shite before you start

I've just had a new kitchen fitted and the appliances were all plugged into a socket it the cupboard next to them. If you put your socket in the built under oven housing it my get a tad hot but also you would need to remove the oven each time. Seems to make more sense to put it into a cupboard next to the oven housing,

However - Den is the man in the know but on his Holiboobs in Englandshire however may be back this weekend.

Thanks, however
The socket is on the wall inside the housing (150mm off floor) its not a surface mounted box.

Just plug it into the socket, no isolater required, that's why it's got a 13A plug on it, wouldn't be allowed to sell it in this country otherwise.

The load from the oven is sufficiently low to connect to the normal ring. You would only need isolator if you had the full oven/hob, which requires larger cable, it's own circuit breaker and isolater due to the higher load.

3000w / 240v = 12A

Ps I am a sparky by day

depends on a few things,state of your existing wiring/circuits. regs only advise that anything over 2kw & above should be on a separate circuit is to prevent the RFC, that it would normally be plugged into, from being loaded for long periods of time.
your oven is likely to be on for a long time & if your washing machine & what ever else you've got on that ring will soon mount up but it is essentially designed to be plugged into a standard ring although if it were me i would provide a separate circuit with all that goes with it.

 

[Benside]

Fair point Morty.
Although if my memory serves me right I think the regs refer to fixed appliances (something permanently wired in not plugged in)

Your washing machine is probably about 2-3kw (incidentally not on its own circuit.) and your kettle is probably 2kw. So if you have everything on together it will probably trip the circuit breaker.

If the wiring for a cooker is not already installed in the kitchen, it will probably not be cheap ( depending on how easy or hard the job might be) to get a sparky in to fit it.
Bottom line is there is nothing to stop you plugging it in to the socket under normal circumstances. I've seen ovens plugged in like this on a couple of occasions with no apparent problem.

 

[morty]

yep your right benside it is for fixed appliances. .plug it in give a go & if you find you get transient trips throw a cable in or don't use all your appliances at once

Thats what i thought, done exactly this three times for familly, only once did i switch the socket above the worktop and this was a property we were selling, this job is first one ive done for joe public so just wanted to be 100%.

im a bit worried about the sparky ive chosen this time as the cooking area is planned about 3m away from where it is now, on the list of materials he has requested he put a 45amp cooker switch but didnt ask for any cable higher than 2.5mm should i be concerned ? used him once before on a much smaller job and he seemed competent
Thanks for your help

Nothing wrong with putting a 45a switch in. Personally I would just fit a 20a double pole switch, does exactly the same thing. Difference in price is minimal (£5 or so) but pointless putting the higher rated switch in without bigger cable and circuit breaker.
