cooker cable size

[kfelec]

just a quick 1

got a job 2 connect a oven (no hobs)

power 3200-3500
current 13-15 amp

in the maual it says it has to be on a 30-32 amp supply and 4mm heat resistance cable must be used to connect the cooker to the outlet

could you use 2.5mm heat resistance cable to connect from the cooker to the outlet with it being cappable of handling 15 amps or is it 4mm for a reason?

forgot to mension the circuit for the oven in the property at the moment is a 20amp supply and 4mm cable

Take the easy option, and do as they say I think!

 

[kfelec]

got loads of 2.5mm but no 4mm that was why but i agree i will have to get some 4mm then

I suppose you can't have 2.5 mm flex protected by a 32 amp supply.

Then again, I would have thought 2.5 mm cable protected by 20 amp supply would be fine for a 3500 W oven...

 

[kfelec]

thats what i was thinking, to be honest i went to two electrical wholesales today for 4mm flex and both of them said they would have to order me it in

 

[sparkwright]

Is the oven a foreign (European) product by any chance?

I'm not saying you should ignore the instructions btw.

power 3200-3500
current 13-15 amp

Is that 3200 AND 3500 i.e. two elements therefore 28A ?

 

[kfelec]

no im sure it was made in the uk

 

[kfelec]

efl....... no but that was what i thought

normaly when in fitting cookers ect it just gives you the specification

not what cable, supply to use ect

Methinks that the power and current variations relate to the possible supply voltage variations (220-240v, perhaps).

 

[kfelec]

good point

My oven is fitted with 4mm heat resistant flex, and I remember having trouble getting hold of it. I ended up ordering from TLC in the end as none of my local wholesalers stocked it.

Having said that however my oven is a double oven and is rated at around 6kW (I don't remember the exact figure).

I don't see any reason why the oven you're looking at couldn't be fitted with 2.5mm flex on a 20A, or even 16A, breaker. But on the other hand I'd always try to observe the manufacturers instructions

220 - 230.

3200W at 220v is ________W at 230v?

But I make the current 14.6 - 15.1....
