Cable requirements for wiring an AEG induction hob

[shd1970]

I am currently about to have fitted an AEG induction hob, model HK654200FB

The technical data in the supplied AEG docs reads :

Model HK654200FB
Typ 60 GAD D5 AU
Induction 7.4kW
PNC 949 597 199 00
220-240V 50-60Hz

Cooking Zones / Nominal Power (maximum heat setting) [W] / Power Function [W]
left front / 2300 / 3700
left rear / 1800 / 2800
right front / 1400 / 2500
right rear / 1800 / 2800

The hob is situated approx within 3m distance of the RCD board

The doc also mentions :

Connection Cable - "For a single phase ot two phase connection, use the cable type H05BB-F or H03V2V2-F which withstands a temperature of 70c or higher"

Can anyone confirm for me please :

1. The correct fuse rating required on the board
2. What thickness supply cable needs to be run from the board to the hob
   
3. Is a separate connection cable actually required, or can the grey supply cable be hardwired to the hob, assuming there is enough spare

TIA

1. 32 amp.
2. 4mm
3. Ask your sparks for advice on this.

In fact he would be the best one to advise on all of this.

Sean - re electrician, this is a new circuit, so in England and Wales it is notifiable work - either you

1. use an electrician who is registered to self-certify Building Regulations compliance, or
   
2. before you start you engage the services of a registered 3rd-party certifier, or
3. before you start you apply for Building Regulations approval

Thanks for the replies

Yes I have engaged a spark and he will be supplying the necessary paperwork as well as doing the work

My questions were more born from the point of view of wanting to educate myself and understand truly if a manufacturer says to use a specific cable, is it truly necessary

My questions were more born from the point of view of wanting to educate myself and know that if i ask the question about the special connection cable as mentioned in the AEG instructions, that i wont get fobbed off for the ease of getting the job done

If you don't trust your electrician, which appears to be the case, you should find another you can trust.

For information manufacturers instructions are guidance only and don't have to be strictly followed. In some cases they are even wrong.

which withstands a temperature of 70c or higher

Standard PVC insulated cables are suitable for 70C.

I hadn't thought about this:

withstands a temperature of 70c or higher"

That's a claim that there is no upper limit on the temperature it will withstand.

 

[Taylortwocities]

Probably they mean that the cable should not be rated at less than 70°C

Maybe it’s too difficult to specify that.

 

[EFLImpudence]

That's a claim that there is no upper limit on the temperature it will withstand.

It's not a claim, but a requirement.

Like "use a cable that withstands 16A or higher".

 

[ban-all-sheds]

Hmmm.

If they had said "use a cable type which withstands a temperature of 70c or higher" I'd agree.

But they didn't - they said "use the cable type H05BB-F or H03V2V2-F which withstands a temperature of 70c or higher".

 

[EFLImpudence]

Yes, fair enough - confusing.

Don't both those cables have a rating of 90°C?
