Hob Wiring

[Ninanina]

I don't know if there are any electricians on here but thought I'd post this as it's totally flummoxed me...

I have purchased a new induction cooker hob to replace my previous hob which was tripping the house rcd's and it was about time I had a new one anyway

However I just don't understand how to wire it up... behind my cooker I have a 30a junction with the standard Live, Neutral and Earth feeds... the recommended cable to come from the 30a junction to the hob is a cable called: H05V2V2-F.... I have purchased a length of this cable but it has 4 x wires coloured: Brown, Black, Grey and Yellow/Green

Apparently you have to use the H05V2V2-F cable or the warranty of the hob is voided, something to do with fire retardancy

Can anyone help how I wire in the 4 x wires into the 3 x junction

Also the hob end connections are: 1, 2, 3, N (Neutral) and Earth so again how on earth can you make 4 x wires fit the 5 x connections?

Thanks for any help

I would think you should be using the 3 core version for operation on 220-240V~: use an H05V2V2-F type three-core
cable (3 x 2.5 mm2).

The make and model of the hob may help for someone to advise.

If you don't know what you're doing get an electrician in to connect it up.
I found this with the cable type number you listed, and it's a massive fire risk if you use the wrong diameter cable http://www.doncastercables.com/cable...Ordinary-Duty/

The hob is an AEG HK654200FB if that helps

It is rated at 7.4 kW

4 and 5 core is for using on 3 phase. which it wont be if you are in a house ie 380/415 volts 2.5mm is 24 amp cable

From the manual http://www.electrolux-ui.com//Docume...311502umEN.pdf:

Use the correct mains cable of type H05BB-F Tmax 90°C (or higher) for a single phase or
two phase connection.

It sounds like you bought a two phase cable by mistake.

Hi Kevin the cable I have was purchased from AEG direct and it would seem that the HO5BB-F Tmax cable is just not available anywhere

I also think that the cable AEG supplied is for 2 phase....

Do you have any copper links?

Does this help?

If you have any doubts, you need to get a qualified electrician to do this....

if they say its the right cable then it must be continental 2 phase or something like that. but the spec of the hob is 30 amps usage which is so close to your breaker limits it will likely blow again. they must be using double into single to work it I imagine.
