Oven installation question.

[Ian Rogers]

Hi,

I have a scenario I would like some opinions on please.

I have 2 ovens, one on top of the other.
Oven 1 – 3.5kW (not yet installed)
Oven 2 – 3.5kW

Each feeding into a common heavy duty Bakelite Junction box. Each using the cable hardwired to the appliance by the manufacturer (So I assume these cables are sufficient).

The Bakelite Junction box then connects to (big red) Cooker Switch using 6mm flat cable.

Cooker Switch finally goes back to fuse box where there is a dedicated 32A breaker.

There is nothing else connected to this circuit.

Oven 1 (3.5kW) is a new replacement oven for a previous oven which was only 2.5kW.

Original installation was 13 years ago (Not sure if regs have changed since then).

Can anyone please tell me if I can just wire the new 3.5kW oven in to the junction box as a direct replacement of the 2.5kW oven? If not, what alternative options do I have?

Thanks in advance.

Ian.

That would be allowable Ian - it may be a good idea to update the Bakelite junction to something more up to date but that is up to you as long as terminations are neat and spot on for tightness.
Each of your ovens will equate to 15 amps but even though on together (but acting separately) they will be cycling thermostatically and so never overload the circuit via the 6mm.
Welcome to the forum by the way.

As Rpa07 said.

I'd use one of these.

Thank you for your replies guys.
What's the name of that box? Or can you provide a link to it or something similar? Cheers, Ian.

Thank you very much telectrix.

It's worth noting that cooker connection plate needs to be fitted to a standard back box, it's not a surface mount item on its own like a joint box is.

Click do a surface mount patress box for theirs though.
