Cooker question

**tears200** · 27-12-2011

Hi hope everyone had a great christmas, i am installing a belling b160 mf cooker its a electric cooker and gas hob, its rated 2.5kw. The manual says it needs fusing at 13 amp, this is where im stuck. I am running a 6mm cable from the board with a 32 amp breaker then where do i go to a cooker connection unit and on the out going connect a spur, please help. thank you for taking the time to read this.

2.5KW?? your choice whether you use 6mm2 but IMO its a bit overkill for a single oven at 2.5kw. But its always there for the future if your installing electric hob/double oven. Take the 6mm2 to an accessable 32a d.p isolator then connect a single socket on the load side of the isolator (still use 6mm2 though),with some butile/heat proof flex 1.5mm2 connect into oven with a plugtop. Plug it in and job done, Use 32amp r.c.b.o though (not 32amp breaker) unless it complies without using rcbo protection.

You should work out the total load and apply diversity. That will tell you what breaker and cable you should use if the manufacturers manual does not give this information.
If you're unable to do this you should consult an electrician mate

or fit a FCU in place of the cooker outlet point.

Use 32amp r.c.b.o though (not 32amp breaker) unless it complies without using rcbo protection.

his 32A breaker may already be |RCD protected.

Yep fair point, split load board or rcd main switch could be in place

think you could all be over sizing mcb/rcbo 2.5kw cooker =10.86 amp therefore 16a would be fine. put a twin socket on load end instead of single then u got a supply for ignitor for gas hob.

Wouldnt u have a seperate isolator for the hob ignition?

can have 2 cooking appliances off 1 isolator as long as they are close by think its 2mtr without checking

Guys, don't you think this is a wind up? Have a good read of the OP. It's either that or someone who should not be playing with electricity imho.

**mackers** · 27-12-2011

ye maybe so trev electric gas cooker thats nearly as bad as a duckdooo

**trev** · 27-12-2011

It could be an electric oven with a seperate gas hob BUT what's the one thing that always comes with new appliances????
That's right a manual. In the manual there's always a section about supplying power and usually with an oven of this wattage there's usually a nice little drawing of a hand holding a plug top heading in the general direction of a socket outlet.
If the OP is a spark he/she should know that it's recommended to be on it's own circuit but would also know about sizing cables, MCBs/RCBOs, diversity and isolation. If the poster is not a spark my advice to call one in is perfect for the situation.
Pending further info from the poster, I'm off

You can easily put this on a plug top, but I prefer a flex outlet plate, more room to work in

Hi if the cooker is 2.5Kw you could run it on a BS1363 plug and socket but anything over 2kw is generally best practice connecting with a fused connection unit.
I would make sure you have RCD protection for this circuit so either run it off an mcb from a split board or run it from a 20A RCBO (32A is fairly high for a 2.5kw appliance).

Having said all this if you upgrade you cooker in future to a higher kw rating it might make sense to install a bigger cable now. Remember the protective device is there to protect the cable catching fire so it depends on what size cable you run.

The 32A protective device is there to protect the cable, ...Not the appliance!!

If he is coming off a CCU and the cable reduction is 3m or less, then he can connect directly to the CCU terminals. Or, if there is a point/back box being connected directly to the CCU, then he could either make this either a FCU or a single socket outlet to supply this 2.5KW oven....
