Electric oven replacement

[Reddog10]

I am replacing an old electric oven (2.3 kW) with a new one of 2.9 kW.

Both will be hard wired and appreciate that the new oven will come without a cable and propose Using 1.5 Mm 3 core butyl heat resistant cable ( should it be 2.5mm? ) in order to install

Does this make sense or M I missing something?

Thanks

1.5mm will handle 2.9KW so it is OK in that respect.

But what size fuse or MCB is protecting the cable?

 

[Reddog10]

The cooker switch on the Fuse Box / circuit breaker says mtn132/b32. 6000 which I believe denotes 32a ?

Is there any benefit to going for 2.5mm?

Also the electric hob is wired into the same socket both controlled by a separate cooker switch

Thanks

I think you are right. b32 is normal for a cooker / oven circuit.

I'm not qualified to give advice on this, so hopefully someone else will give you a better answer. The 'benefit' of a bigger cable is that your house doesn't burn down if the cable has to deal with more current (Amps) that the breaker is designed to trip at. You may need 4mm cable, or downrate the MCB to a b20.

Also the electric hob is wired into the same socket both controlled by a separate cooker switch

As above, I don't know exactly what is allowed on one circuit with fixed appliances, so my whole reply might be nonsense.

Thanks

You are welcome. And welcome to the forum. I hope you get some proper advice without this thread being thrown off topic (Most topics lately have been hijacked by a member who manages to not get banned, please try to ignore any attempts to reply to her/him)

Correct.

Not really.
Cookers and hobs will not overload the circuit.

Both on the same circuit is fine.
I presume you do not mean 'socket'.
There are double cooker outlet connectors.

ThanMs both that's very helpful.

Yes the 'socket' is a cooker outlet plate.

With an induction model - 3kw - says it needs a 13 amp fuse but I propose hardwiring it into the existing 32 amp circuit as there's no 13 amp socket in that location.

The previous set up was similar oven / hob above so I think this should be ok but any advice welcomed

Sorry that thread should have started with replacing existing electric hob with an induction hob

Thanks
