Electric Hob Wiring.
9 Answers
I disconnected an electric hob for a friend that had 6 wires connected to it via a 6 wire cable. It was 2 earths, 2 neutral and 2 live. He then got it reinstalled by someone else but says now that only 2 of the hobs are working.
I'm assuming that maybe the cable in the new location is a normal 3 wire electric cable and this could be the issue, not 100% sure as I've not seen it yet.
I took a picture of the connections when I disconnected it. If it is only a 3 wire cable at the new premises can the hob be wired up using a link across using the cable that's there?

Maybe there are two banks from the controls. If so, then putting in links may result in all four hotplates coming on at once.
I'm just guessing here. To be sure, you really do need to download the wiring installation instructions for the particular hob.

Our AEG hob is exactly like this. It allows for a house with 3-phase electricity to share the phases. (Rare in the U.K. but common in some countries.) our installation instructions specifically state that you can install the links for use on a single-phase supply. It is, however, then extremely important to use sufficiently thick cable for the supply circuit. When all the rings are on, these hobs can pull 8 or 10 Kwatts. That may be why the original cable was effectively 2 x 3 wires.
Your friend should also be careful of the legality of this kind of electrical work. It should, by law, only be carried out by a qualified electrician who should give him a certificate. (A pain I know, but errors in this kind of work causes house fires.) I believe that it's also possible to have the work certified after the event, but this can be as expensive as getting a qualified person in the first place.

IMHO 2.5mm cable is dangerously small for this kind of unit unless you double it up (& then remove the links). There are specific ways to calculate the minimum cable size according to the maximum wattage of the appliance. The way it was originally installed rather indicates that single 2.5mm is insufficient.
Another boring legal implication of this is that improper electrical installation can invalidate your house insurance. Not very nice to be told after a fire that they won't pay up as their experts have found that it was caused by an inadequate electrical installation.
