Cooker tripping

RIchol · Sunday at 9:20 PM

Hi. I have a rental property where the cooker trips the electrics. Initially I had the cooker elements replaced. It still tripped. I replaced the cooker with new. An electrician has test the wiring and says it is safe. He replaced the circuit breaker with a 40a. It still trips. He doesn't know why. Can you help? Thankyou

Moved from electrician talk

If the electrician does not know why, I doubt anyone on here will be able to help you.

What trips? An MCB an RCD or an RCBO.

What makes it trip? One particular element, or when you turn everything on at once?

Did your electrician test anything on the cooker?

Hi. Thanks for replying. I think it's when everything is turned on. It is the breaker on the main board. The issue was the same with the previous cooker. The current cooker was new a couple weeks ago. I think I'll ask him to replace the cable between cooker and breaker. I wondered if it might be the wire being nipped by screws on new kitchen Units. The house also had a rat in it during covid. It had an electric safety check and the electrician tested the cooker circuit with high voltage meter. He says that woukd show any weakness in the cable. If it's not the cooker, the cable or the breaker, could it be anything else?

Can you post a picture of the load info plate normally found of the back of cooker or sometimes in the jamb of the oven door

This is the cooker. Sorry, I'm not in the house where it is

If it's tripping on over current changing a cable won't fix that. You don't normally put all 4 rings and the oven on at the same time.

Out of interest, have you tried running just the oven, or grill or rings for any length of time. It might be a dodgy element even if it is new.

Thanks. Telling tenants not to turn everything on isn't easy. I'll go down myself and try different combinations. Thanks for your help

So the spec for that cooker says 35amp and to trip a 40A breaker you would at least 60 - 70A as a minimum and it would probably take a while to trip for an instantaneous trip you would need a lot higher amperage flowing

So that leaves the usual suspect could it be an RCD that is tripping ( a picture the board and an indication of what is tripping would help), from past experience with electric cookers and RCD's they are not a good mix especially as the cooker ages and I have seen the ocassional new cooker have problems possibly due to being stored in a cold / damp warehouse prior to despatch

From what you have said so far I doubt your electrician is up to finding the fault I would suggest you find another electrician that can

Agreed.
Many years ago some cooker manufactures instructions used to state do not connect this item via an RCD..
Which I understood to be due to some natural leakage that can happen with some heating elements.

I would agree the electrician doesn't sound the brightest when it comes o fault investigation.. ?

However as mentioned we need to know if this is an MCB only supply, MCB & RCD supply, or RCBO supply..
As the phrase the breaker tripped doesn't offer much assistance to working out what may be happening. ??

This reminds me of a job coming up to christmas many years ago we sent an electrician to an RCD tripping fault house was on mural wired main with an earth rod, the electrician cleared the fault by replacing a dodgy element, similar happened a few days later and fixed again the third time it happened sent the same electrician again he came back into the office smiling and told us that he had definitely fixed it this time when asked how he could be so certain he told us he had taken her to the gas cooker shop for a new gas cooker

Instead of asking your electrician to carry out a specific task, ask them to find and fix the fault… Ive had a fault on a lighting circuit only show itself when the cooker was being used (would trip the RCD), the cooker circuit was perfect

These are the images of the circuit board. The cooker is the one with the smudged writing under.

It seems that the circuit trips even when 1 hob is on for long enough.

Does your cooker switch have a socket?
Does it still trip if a kettle is plugged into it?

UNG · Monday at 9:47 PM

I don't suppose the electrician is the same one who has his sticker on the CU?

Missing a blank on the left.
