oven circuit or not?

[Robo]

Customer has handed me a quote and a 6mm oven circuit has been priced for. She only intends on putting a single oven in. the hob is a seperate gas item. Am i ok to tap into the kitchen ring to power this. Mine at home as a 13a plug top. Or would it be better to put a seprate 6mm feed and outlet plate.

 

[pushrod]

depends on the power of the oven and what else is on the ring, but a 6mm radial is the sensible way to go as it allows more for changes in the future.

spur the ignitor for the gas hob off the ring

find out the wattage of the oven then run either 4mm or 6mm to a dp switch then to an outlet

onsite guide says somewhere that an oven upto something like 2.2kw is perfectly fine plugged into the kitchen ring final circuit. At the end of the day, there are plenty of other applainces that sap more juice! Obviously, you have to provide isolation as it is a built in appliance and just having a socket behind the oven isn;t good enough!

House has a seperate 32a ring for the kitchen. Just the usual appliances to be plugged in.I will say if they get a single fan oven upto 2.2kw then i will spur off the ring. using a fcu as isolation. A larger oven and a 6mm circuit needs to be introduced. Thanks

only prob there is if oven developed a N/E fault, it would trip RCD so dead kitchen ring. instead of FCU i would fit 20A D/P isolator as oven is fused at it's plug top. then socket for oven can be behind it

ok doke. 20 a dp switch incorporated into ring and then down to socket. thanks

I'm with pushrod on this. If at all possible I put in a seperate circuit even if it only a single oven with a fitted plug.

 

[Robo]

Ok doke so 32A 6mm feed to cooker sw then to outlet.

 

[telectrix]

good idea, then if the oven has a plug on it, you can fit a socket as outlet. future proof as SirKit says as a larger, hard wired oven can be fitteed at the cost only of changing socket for hard wired.conn. outlet

 

[Robo]

can i put a 32a 6mm feed to 45a sw. Then to a double socket topower hob ignitor and oven. This is still future proof or would i b best to have hob on fcu off the ring toprovide seperate isolation.?

 

[malcolmsanford]

You certainly can but when it comes to future proofing there is only so much you can do. What's to say that sometime in the future someone will fit a double oven with induction hob and that will need a 10mm^ 50amp supply. So you 6mm^ will not do.

If it is a sinlge oven and can use a BS 1363 plug top then it can plug into a 13amp Socket. In appendix 15 it does recommentd that any 2k cookers, ovens and hobs not be plugged into a ring final circuit but to have it's own dedicated radial.

But then as always in the BRB it contradicts itself in 433.1 by saying you can plug a load in as longs as the loads is unlikely to exceed for long periods the current carrying capacity of the cable.

So as appendix 15 does actually state the appliances I would fit a radial.

Thanks, i will fit 32A 6mm radial to a 45a cook sw. Then to a double socket. this will then power hob ignitor plus oven. And is future proof for a slightly larger oven. cheers
