Electric Cooker connection question.

uncle_buck_3

Hi,
When connecting a built in electric oven (5 kW) & ceramic hob (6.5 kW) what would be the recommended method of connection?
…..do the regs allow you to put both the cables into the single cooker connection point?

Don't they say it has to be fitted by a competent pro now?

I think uncle_buck is just checking up that his NICEIC registered, Part-P qualified electrician is telling the truth.

Yes they do actually.

I figured.

'Volts' are irrelevant.

you could go up in smoke!

Very true

cookers on a seprate main ring

Cookers are installed on a single 'radial' circuit, not a 'ring'.



The answer to the OP's question is...

Yes, both applicances can be connected to the one isolation/switching device.

However, other factors will come into play (cable sizing, application of diversity, selection of appropriate protective device, grouping, thermal insulating barriers, and length of cable run).

As Al Mac says, you need a professional.

Thanks for that…. I wasn’t sure if the regs allowed you to connect like this.



Yeah I’ve done the diversity calculation….. (10 A + 30% balance + 5 A for socket)

Total load 11.5 kW….(No socket)

11500 / 240 = 47.91A (call it 48)

48A – 10A = 38A

38A / 30% = 11.4A

10A + 11.4A = 21.4A

The new cooker / hob will be fed from the existing cooker point that is fed in 6mm T&E with a 30A cartridge fuse.


….Yeah I am just checking that the NICEIC registered, Part-P qualified electrician that is doing the job isn’t cutting any corners


UB.
