installing oven/hob

[offaman]

Hi all.
I am about to replace a duel fuel range cooker with a single built in oven and a ceramic hob. The house is 9yrs old and the cooker was installed by the builder. The existing supply is to a cooker control unit. This circuit is protected by a 32a mcb. and i suspect that the cable to this is 6mm.
From ccu there is a junction box to which the old cooker was connected.
And from the junction box is an unswitched thee pin socket. with nothing conected.
The new set up will be a 3kw oven and a hotplate 6.7kw. the oven manual states that the oven should be connected to a ccu. I assume that I will have to have an additional ccu ( inststalled by electrician0 to the oven. Could anyone confirm this .Thanks

10.7 Kw = 46 amps which would probably mean a 10mm cable depending on the installation method & a bigger circuit breaker, but allowing for diversity may bring it within limits, but I am not 100% sure. You may be better posting this in the electrical section fo a more difinitive answer.

The 3kw oven normally goes in on a standard 13 amp plug so you will need a socket to the rear .The existing cooker circuit should support the hob. [unless an electrician knows otherwise?]

3KW @ 230v =13A, 3KW @240V =12.5A, which means you may be pushing a normal pl/skt to it's limits
