Hi we bought an induction hob recently, but it hasnt been delivered yet. The electrician is asking me what thickness of wire is required? He say he can figure this out from the wattage of the hob if anyone knows? Its an electrolux one if that makes a difference. We are aware that it needs a seperate breaker at the fuse box.
 
It has the same rating as an electric cooker - so needs to be on 32 amp (i think) rating....
 
Dont think he is much of a spark if he needs you to tell him, did you give him the make and model? and if so he should have the cop-on to know what it needs.
Sounds like a lazy person. Maybe you need a better spark, try google some good firms there and they are cheaper than the ones in the yellow pages as they do not need to pay the crazy money that the golden pages charge for advertising.

Simply type in the search box Electrician and your area and they will give you some firms. I find it great, we found a really good firm that way.
 
If this guy can not tell you the size of cable required he can not be qualified electrican.
 
Do not under any circumsances run an electric hob off a 13amp socket, always check the duty and follow the Maunfacturers instructions.
Some induction hobs use between 6.6kw and 7.2 kw
All this from from a 13amp fuse .. Hellooooo!!! I dont think so.
13 amp fuses should never exceed 3.2kw and thats sailing pretty close to the wind.
Maybe a a gas hob with and electric ignition can be connected in this manner.
The supply to the hob should be a clean supply from the board in min 6sq cable and fused as per the manufacturers instructions.
Undersizing the fuse will mean it will constantly blow.
If you undersize the cable you will have a fire.
A little knowledge is a dangerous thing, a very dangerius thing.

This electrician is 100% correct, he does need to know the wattage of the hob, in order to determine the size of the cable.

Just knowing the brand name and model is not enough information for him, he does require to know the wattage. Some models of various bits of electrical equipment are available with different wattage ratings, just like a particular model of car comes with different engine size.

By knowing the wattage he can after taking into account the proposed route of the cable calculate the size of the cable. The required cable could even end up as being as large as 10mm2, the size does depend on many factors, so the electrician is correct to ensure he knows the rating before he starts work.
 
Theengineer is 100% correct in what he is saying.
However; The specs on most appliances are available via the internet etc, each model number normally with domestic aplicances they have specfic specfication.
Check the data plate on the appliace also this should correspond with the Manual/Instructions that are supplied with the unit as sometimes the litrature suppled can cover a mumber of model number or variations of the model number.
As a matter of courtessy would the spark not find this information.
The spark should also, when he has this information, make sure the existing service is capable of dealing with the load required.
Best way is to find a contractor you are 100% comfortable with and proceed with peace of mind.
Best rule of thumb is speak to a few Electricians and go with the one you feel most comfortable with even if he/she is not the least expensive.
 
It is not the electricians job to go seaching for manuals or specifications online for a product that hasn't even arrived yet. The person buying the hob needs to get that information & supply it to the electrician. If the electrician has to spend a couple of hours looking for information like that from a manufacturer somebody has to pay.
He needs to know the kw rating of the appliance to see if the cable feeding the supply point is the right size for the appliance being connected and that the mcb backing it up is also correct.
