Cooker cable?

[Stever_777]

Hi guys, ive just run in a new circuit for a 11,5kW cooker with 6mm T & E which has a gas hob.

Q. Can I use normal grey 6mm T&E from the cooker to the outlet plate or does it need to be heat resistant cable, cause I cant find any heat resistant cable that size in the TLC catalouge?

Thanks

Most are done with normal 6242Y twin & earth but for a belt and braces approach, you can use 3183TQ 4mm (heat resistant flex) depending on the protective device.

On a 40A MCB and a 30mA RCD?

what % of that 11.5kw is the electric oven/s.

I`d better go with the 6mm T & E on a 40A MCB

Cheers

Well its gas hob so all of the 11.5 is oven mate

Is it an on or off type of device or can diversity be applied?

i can't see the oven drawing 48A, not unless it's commercial.

what do you mean by an on or off type device mate?

 

[telectrix]

he means that is it all on at once, i.e.all elements on together.

what is your installation method for the 6mm t and e on the 40A MCB

Well if it's a diverse load (say 4 elements individually controlled) as opposed to the whole load being just on or off then you can justify the application of some diversity.

As far as I can remember, there appears to be probably 3 different heating spaces, its one of these 900mm wide 5 gas burner jobbies

i still can't see the oven/grill etc being 11.5kW. however, if you apply diversity to 11.5kW, its. 10A+12.7A, =22.7A.
