Cooker wiring....

[KingboyD]

Hi, I know this is covered alot here but not exactly to what I need to know.

I am installing a cooker that is rated at 9.8/10.7kW, will 6mm cable and a 30A circuit braker be sufficiant for this job or should I go for 10mm cable and a bigger circuit braker?


Thanks

Sigh... If you do a search, you'll find loads on the formula used for this calc. Many prefer to use flc and design the circuit round that.

I just wanted to know if what I am going to do is safe or not?

10.7kW divided by (say) 220v is 48Amps.

Enough to trip a 32A MCB "immediately"

Seems a lot.

Have you got a restaurant or what?

Sigh two. If you leave it like it is and connect your new cooker then its safe. Its just that the MCB will trip with annoying regularity. So safe, yes. Workable, no.

it'll trip it pretty quick but probablly not immediately.

the question you have to ask is do you often use everything at once and do you turn everything on from cold at once.

personally i'd say stick it on the existing circuit and upgrade it if it trips too often.
