I have recently removed my old 2.8kw oven and 5.5kw ceramic hob and will replace it for a 2.9kw 13 amp hob and a 3.1kw oven.
The electrics seem to be 4mm T+E (hard to tell so could be 6mm). They were both wired into a twin socket, the old oven was on a 13a plug which was spurd from the hob connection block, this ran up to a cooker isolation switch and then to a 32amp breaker.
I would like to know if I can plug the new 13amp hob into the socket the old oven was plugged into and then hardwire the new 3.1kw oven into where the old hob was wired into.
Update:
There is nothing else on this circuit, only the hob and oven. Can I not hard wire both appliances to this circuit?
Are you a tradesperson and able to answer this question?
No you can't run these of a Twin socket outlet. The maximum fuse size is 13Amp for each outlet.
The new 2.9kw hob can technically run off a 13Amp socket outlet as the maximum current draw would be around 12.6 Amps. But this should be controlled using a Cooker Isolation point and should not be run of a 13A socket.
The new 3.1kw oven can not run off a 13Amp socket outlet as the maximum current it can draw would be around 13.5 Amps i.e. it would potentially blow the fuse in the plug.
The 32Amp breaker is fine for these two appliances but that also depends on what else is connected to the circuit, as there may be other appliances on there.
So in answer to your question is No!
I always run a separate circuit for either a "combined hob/oven" or a separate oven and hob, nothing else is connected to that circuit, I use 6mm cable (for future proof) back to the consumer unit on a 32Amp/40Amp RCBO/MCB. Most ovens and hob's that I install are close to each other and I tend to install a "Dual" cooker connection point and run a separate heat resistant flex connection to the oven and hob.
I would recommend getting a qualified Electrician to look at this for you!
(In answer to the second part of the question, Yes they can be hardwired in but not via a 13 Amp socket outlet. The same way as I have mentioned above but still using the existing 4mm cable rather than running a new 6mm cable)
