Hi,

My current oven is a whirlpool 2.3kw hardwired to a 13amp switched spur.

The oven I’m thinking of buying is 13amp and requires a 2.1kw connection.

Can I use the cable from the existing oven and connect it to the new oven?

If so, is it legal to do it myself?

Thanks in advance!

Yes you can use the same cable as long as it is in good condition. Obviously it would be advisable to check that the cable is on a correctly rated circuit.

Thanks for your reply. How do I check that the cable is on a correctly rated circuit? At the consumer unit?

It is legal to replace like for like. I imagine your new oven would come with a plug. The temptation maybe to remove the plug and put it in the spur. However that may void the manufacturers guarantee. So you may have to change the FCU to a single socket outlet. There is of course the testing one would need to do. If you have any recent certificates for that circuit you may well be ok. In your case as you can't do testing then you would be on the basis of close your eyes and hope for the best.

yes. at the consumer unit. I expect the circuit would be properly rated but it is worth a check. It would tend to be a 32a ring final circuit or a 40amp radial in 6mm cable.

According to the AO website the new oven will not come with a cable.

Can we not assume it’s correctly rated as there is an existing oven?

I have attached photos of the consumer unit and fused switch in cupboard next to oven

well on the cu it is labelled as cooker socket so i presume it is referring to that fcu you attached a picture of. and that appears to be not correctly rated unless there is another fcu that downrates that fcu - as it appears to be a 2.5mm radial on a 32A breaker - and that is a no-no
 
Also the flex running out of the fcu to the cooker might not be the correct rating. if you could find out what size that flex is that would be helpful. it should faintly say on the flex itself.

Hi - just going from the picture, the existing flex might be damaged. It might just be a mark but if the insulation is damaged it should be replaced with a new length of 1.5mm.

We’ve only been in the house 10 months and already suspect that the previous owner was a bit slap dash with the electrics. I was hoping it would be a simple swap given the similar amperage and kw rating of new oven. I think it best to get a professional in just in case what’s already there is insufficient (a c*ck up! ).

Thank you all for your quick replies!
 
no problem. your main problems are the size of cables. also i dont think any of the circuits are rcd protected so the sparky will probably recommend you install a rcd

Don't poke anything into the JB beside the coat hook, or in the hole in the box beside that

This is the cooker/hob switch so I assume the oven fcu is a spur off that? The fact that there is a circuit in place and say it’s all correct, can the electrician replace the oven even if there isn’t RCD protection? Or is it a case of no rcd protection no work on any kind of electrics - existing and new?
