Built in oven replacement

[peterpjr40]

We have a built in single oven which has seen its last meal. Would like to replace it with a double oven. We have found some with the correct dimensions so fitting shouldn't be a problem, my question relates to electrics.

There is a separate fuse at the consumer unit rated at 30a. The wall switch for the oven is definitely connected to it as I have pulled the fuse to check. The wall switch is wired with 2.5mm in and out and it powers the oven, hob ignition and extractor together with two 13a sockets.

On the basis that the kitchen was fitted professionally in 1988 I assume all of this is ok for the single oven but will it be ok for a double oven?

Thanks for any advice.

2.5mm² is not good on a 30A fuse/MCB. You should rewire the circuit with 6.0mm² cable, OR replace the fuse/MCB with a 20A one.

Either way, a double oven will be fine.

It sounds like the cooker is currently fed off the kitchen ring (maybe, but I could be very wrong). If this is the case then you could either get a replacement single oven, or depending on the kW rating of the new double oven you may need to have a dedicated 30A supply installed
