Induction cooker hardwiring 32amp

[vineeth]

Hi All,

We are in the process of replacing our gas hob to an induction hob (7.35 KW, 32 Amp). Our electrician suggested that we get a radical circuit terminated at a 32 amp RCBO. There are currently double pole switches for exhaust and washing machine hanging from another ring main. Our idea is to have a grid with switches for all three appliance in one grid. Our electrician suggested that he can run the radical circuit to a 32 amp switch module in the grid, and use 20 amp switch modules for the exhaust and washing machine.

Following are my doubts:

1. Should we get a 32 amp or 40 amp RCBO
2. As per the induction cooker, it says "This product requires hardwiring to a 32 Amp fuse". The separate radical circuit and 32 amp switch would suffice?

Thanks in advance

If you don't trust your presumably qualified, experienced and competent electrician, I suggest you find another that you do trust.

Lets be nice.

I would suggest that would be a poor design, to have all such appliances on the one circuit; not a great admirer of using grid switches for appliance, although its used extensively on new builds, primarily to comply with Part M, I think.

What is your current kitchen wiring set up @vineeth?

Go with your spark.

If your spark is suggesting a 32A circuit for the hob, washing machine and cooker hood I would say he’s wrong.

Fixed appliances such as hobs should be on their own dedicated circuit .....

 

[Octopus]

I said that already.

Hum, did you? I would say your response is open to interpretation ..

Do you do a lot of cooking and tend to have all the rings on for a decent amount of time?
That hob is rated at 7.35 kw so right on the limit if you’re an enthusiastic cook

Hey All,

Thanks a lot for the inputs. Guess I was not clear with my original post. Currently there are 2 ring mains:
[1] 32amp ring main where all appliances are connected
[2] Cooker ring main with a combi microwave and an oven.

The plan is to add another 32 amp radical circuit off a RCBO just for the induction cooker. The grid would have two 20amp switches (For dishwasher and exhaust from Ring main 1), and a 32amp switch (For the induction hob from the new 32amp radical circuit.

That would be RADIAL circuit Vin

I was on here talking about racial circuits the other day.

 

[vineeth]

Hey Pete / Charlie / Matt, thanks for the info. I guess the radical circuit would be best option to go for. Just have the doubt on whether I could use that 32 amp switch to hardwire the cooker on to this radical circuit. Hope I am making sense

This all seems awfully complicated.

Errgh?

Even after diversity?

The thing is with those type of hobs is that the combined load of all 4 hobs is about 10kW..
When all hobs are switched on the overall load is reduced..
In some instances I would apply diversity; such as the overall maximum demand but not for a single supply to this type of hob if it is known that it will be used at full power for long durations
