New Induction Hob causing oven to trip

[boris]

Hi

My ceramic hob became cracked (only 18 months old since kitchen re-fitted) so purchased an induction hob to replace it.

I took out the old one and replaced it with the new hob

Since then the electric oven (at the other side of the kitchen) seems to want to trip the fuse board. I have flipped the trip for the hob but the oven is still the one causing the problem as it still trips even when then hob is off, trip is off etc

Is there any way they can be related as its only happened since the new hob fitment so can only assume its that. I am awaiting an electrician to call me back but thought I would check on here in the meantime?

Any advice would be great

Are the oven and hob on separate circuits back to the CU, or on a combined circuit fed maybe via a wall cooker control unit to two appliance wall switches?? Also what's actually tripping, an RCD device or a breaker (MCB)??

Thanks for the reply

I believe they are on separate circuits as I can flip a switch on the MCB (Fuse Box) to turn the hob off but leave the cooker on. The cooker is plugged into a standard wall socket, the hob goes behind the cupboards so cannot see what it goes too, although its a very thick wires rather than a standard plug type wire.

When the cooker trips out it flips one of the main switches on the MCB so turns off the downstairs lights, sockets etc at the same time, rather than just an individual trip switch

Does that help?

That sounds like an RCD that's tripping!!
Apart from checking the connection you made when installing the new hob, there is very little you can do without test equipement. So i'm afraid you'll need to call in an experienced electrician, who will be able trace out the source of your problem.

I thought that might be the case

Just seemed funny to happen since the new install and wondered if, other then rechecking the conection, there was any other obvious thing that could cause it.

I guess its down to the expert, when he eventually gets back in touch!

Thanks any way!!

Yes, ....unfortunately it will need test equipment and an electrician that knows how to use it, to get to the source of your problem.


Maybe if you make your local area known, someone here lives close by and maybe able to help you out.

Thanks, I am in Sheffield. Any local electricians who are available now. Do PM me!

Just one final thing though. The old hob had a single connection for live and a single one for neutral, whereas the new hob gives the option for 2 connections for both live and neutral. Why is this?
