Cooker wiring query
Discussion
We're having a new kitchen installed at the moment which is going very well. However, I used to be an electrician although not now qualified to latest regs.
I noticed today after the Installers left that they are going to fit and wire our existing cooker tomorrow which is rated at 2.9kw, so will take 13 amps of current, via a 3 core & earth flexible cable, which looks like 1.5mm on a plug top onto the kitchen ring main, which is on a 32 amp RCD.
We had the consumer unit replaced on day one by a sparks working for the installers and there is a dedicated cooker RCD rated at 32 amps, and the previous 6mm cable has been reconnected and left under the previous location of the cooker with a JB.
Surely at the very least, the cooker should be wired directly to the cooker RCD, with a local isolation switch adjacent to the cooker?
The installers have been doing all the wiring, and the sparks is going to provide an electrical cert for the CU shortly.
Your comments would be appreciated.

Thanks for the snide remarks guys. I should have qualified I packed up sparking over 30 years ago, fo a different career.
Upon further investigation last night, they've wired the induction hob, which is fitted with a 13amp plug, onto the dedicated cooker circuit, using the JB, what looks like 4/6mm cable and via a single socket outlet.
I dropped into conversation this morning my surprise you could wire an oven onto a ring main. The more approachable of the 2 guys said yes, because it was only a single oven. If it had been a double, they would have wired it onto the cooker circuit.

That's a very low power induction hob if it's on a 13A plug. They're usually rated for a 32A dedicated circuit as a typical 4 hob unit will require 5-6kW at peak draw.Upon further investigation last night, they've wired the induction hob, which is fitted with a 13amp plug, onto the dedicated cooker circuit, using the JB, what looks like 4/6mm cable and via a single socket outlet.

That's likely also why they don't wire the oven to the same circuit as it could then be overloaded if you used the hobs and the oven simultaneously.

Our oven is a single and came with a 13amp plug fitted which would certainly back up what you were told. funboxster said:

To me the (slightly) dodgy thing would be: what fuses the lead to the hob or oven if you cut a 13A fused plug off and wire them into a cooker cicuit with a 32A breaker?I dropped into conversation this morning my surprise you could wire an oven onto a ring main.

Certainly our old single oven was pligged in - in reality they're not normally on much even when in use the elements are cycling on and off. As others hav esuggested, the induction hob rating seems low - usually they're far higher but can be down-rated based on the available supply.

Any cooking appliance over 2kw should have its own dedicated radial circuit.
However, many 4 burner induction hobs are now rated sufficiently, that they can be plugged into the socket outlet that was once used for gas hob ignition.
Some single ovens are rated at 16a, due to having a pyro clean function.
So to say it’s a only a single and can be plugged in, is incorrect.

now, why on earth didn't you say that in your first post, instead of trying to be a smart arse?Any cooking appliance over 2kw should have its own dedicated radial circuit.

I'm looking at a new single over and hob. The hobs I have seen all seem to need a 32A supply, which hob did you use that only requires a 13A plug?
TY
It's a Neff-bought last year- model number T40B31X2/GB. Probably has been superseded now. I checked the rating plate on the underside. Interestingly it doesn't quote the power consumption in watts, only maximum current use 13amp, so 3.1KW. TY

The single oven is rated at 2.9KW, the hob at max 13 amp, but no max power consumption in watts given!

Well 13a at 240v is ~3kw
I was aware of that ,as per my earlier post. I still remember I=P/V, P=VxI, etc. just making the point for some reason rated wattage hadn't been stated on the appliance.
