Hi,

I'm installing a zanussi oven and would like a little help please.

The oven manual states "Connection should be via an Oven Control Circuit.
Min size cable 2.5 mm2. Cable PVC twin & earth. Fuse 15 A min 20 A max.
The total load rating of the oven is 2.48 Kw."
The label on the side of the oven states Max power is 2. 790 Kw.

I checked the circuit breaker for the cooker in the consumer unit and it is 32 Amp.

The old oven is wired through 13a fused spur socket on the wall, but uses a 1.5 mm2 cable.
The 13a fused spur socket is wired to the 45a cooker connection unit (with the red switch) on the wall above the working top.
There is also an electric hob - max power 6Kw 40a separately and directly wired to the 45a cooker connection unit.

My plan to install the new zanussi oven is as follows :

1) Replace the 1.5 mm oven power cable with a 2.5 mm one.

2) Replace the 13a fused spur socket with a 20A Double pole switch.

3) Keep the circuit breaker for the cooker in the consumer unit as
it is - 32 Amp

Can anyone see any issues with this ? Thanks,

2.48 Kw is within 13A so a standard fused connection unit (FCU) will do the job, so all you need to do is change cable.

Hi ericmark,

Thanks for your advice. That's fine I can change the wire to 2.5 mm one.
Yes I can use the 13 amp fcu. It just the instructions in the manual which
bother me - "Fuse 15 A min 20 A max".
