Electric touch hob not coming on (plus consumer unit issue)

[crapusername]

I've recently had a new cooker point ran from the consumer unit and have had a new touch control ceramic hob installed on it but could get absolutely nothing from the hob at all, no display or anything. After looking at the consumer unit fuse board I realised the electrician who installed the cooker point had done so on a 6amp circuit breaker instead of a 32amp one.

Would that explain why the hob isn't turning on at all or should it be coming on and tripping the fuse?

You can't rely on the "volt stick", you need someone with a voltage tester to look at it. Has it ever functioned.

No it hasn't, it was a brand new hob (two of them) On a new cooker cable coming from a new consumer unit.

What says it has power?

The led on the isolation switch lights and the volt stick says so too though I understand these are very basic.

"Electrician" connected to a 6amp mcb and 2 seperate new hobs not working

I would suspect that there is a failure and unlike the Hobs it can stand on 2 legs

Yes but as soon as you try to use the Oven/Hob whatever the breaker trips, correct? switch the 32 amp breaker OFF and try you Oven Hob if the indicator doesn't illuminate then the circuit has been wired to the 6 Amp breaker

No, it doesn't trip the breaker. It is as if the hob is getting g no power at all as the display remains completely blank and no matter how many times the buttons (touch screen thing) are pressed there is nothing.

Switching the 32amp breaker on doesn't light the isolation point led but switching the 6amp one does so I would assume it is definitely that one which is being used?

You need to verify if the "mini" consumer unit is actually live, where is it supplied from.

Not sure what you mean "it doesn't trip the breaker" what exactly is the state of the two breakers ON or OFF?

Never thought of that Westy, surely not, no can't be surely?

Are you thinking that he has wired the mini one into the old style existing one? Because that was my first thought but he assures me it is directly from the main meter outside

Nor me until he mentioned it.

Post 6 then .....

Who knows a picture of the meter, old board may help.

Was the bloke that wired the cooker an actual Electrician or a mate fro down the Pub?

6amp breaker on = led lit up on isolation point.
6amp off = led off.
32 amp on: led off
32 amp off = led off.

Attempting to press any buttons on the job itself has no effect on the hob it remains dead and it doesn't trip or switch any of the circuit breakers in either direction. It has been tried with one up and the other down, both up, both down etc and the only one that gives lights the led on the isolation point is 6amp on, 32 off but none give any results on the hob or trip and fuses

He was an actual electrician but didn't notice that the circuit breaker says 32amp on it. I noticed that afterwards

We all use volt sticks but they can give misleading indication. I don't suppose the isolator has a socket on it.
