Cooker and hob

[Chrisarm5]

Hi All

I've recently been doing a kitchen re-wire, everything done, sockets added to ring etc. however for the cooker ive wired a 6mm radial to a cooker switch, then 6mm down to a single socket. As cooker is 2.7kw this is acceptable on a 13a plug top....is this correct?
However now the customer has decided to tell me they're getting a separate electric hob, (this is after 2nd fix) and walls plastered. The info I have on the hob requires a 4mm cable supported by a minimum 32a fuse as the hob is 6500w. How can I do this??

Any help appreciated.

Prepare to upset your client by telling them it needs a new feed, disturbing all that lovely new plaster!

Had this done to me a couple of times, why do people not make decisions at the right time??!

How do I get a feed to this?

Is it acceptable on the same circuit as the cooker?

Easy: Terminate the 6mm cable behind the cooker with a normal (single) cooker outlet and a 13A fused connection unit both mounted in a twin box.

Connect the hob to the cooker outlet, and wire-in the cooker to the 13A FCU

Use the diversity calculation in the on-site guide to prove to yourself that the 6mm cable is in-spec for this load.

Job done.

If the oven has a 13a plug on the end of it you could probably get away with plugging that into the kitchen ring circuit. Then you can use your 6mm as your hob supply?

feed the hob in 6mm from the cooker switch. leave oven socket as is or replace with FCU ( your choice ). whatever disturbance to decor is minimal and your customer will have to accept this.

Why not just replace the socket you have put in with either a cooker switch with socket or a dual outlet plate and connect in both units.

like it. dual outlet box with cooker connection unit one side and a socket of FCU on the other. no disruption then. all below worktop.

will need 13A fuse either in plug top or FCU for the oven.

Clic dual outlet plate, 4 mm to socket mounted next to it. simples

Why not just replace the socket you have put in with either a cooker switch with socket or a dual outlet plate and connect in both units.

If you use a dual outlet plate you will still need either a 13A plug & socket or an FCU (FCU is neater).

Why? Because the manufacturer's instructions for the cooker will say that the device must be fused at 13A. Failing to follow this instruction would be a deviation from BS7671 and is also likely to invalidate the warranty.

Tell me about it!!

I've been helping my builder mate out with his house renovation and very early on I asked what he was going to use for cooking. He told ma an electric oven underneath a gas hob, so I supplied a gas supply and a 2.5 radial for the oven.

Next thing I knew a bloody great all-electric range cooker appeared .................... :banghead:
