Cooker tripping

[RichHol]

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

Is the circuit on and rcd ,is it the mcb that's tripping

What size of cable is feeding cooker.6.00m ,10mm etc

I don't think so. It seems intermittent

Would need to know if it's an rcbo or mcb or rcd covering mcb.what kilowatt is your cooker

I don't know. An electrician has looked at and said it is suitable. They tested with high voltage tester and replaced cooker switch as well as circuit breaker

It's the breaker on the main circuit board

If its intermittent without any more info and you've replaced cooker then could only assume the circuit is the issue ,or maybe there's a join in cable behind wall .if it's a relatively new kitchen you could bet cooker has changed position .photos of consumer unit and cooker may help

Thanks Jock. The kitchen was replaced but cooker in same place. I think I'll ask the electrician to replace cable from cooker to breaker.

Maybe ask him to perform continuity tests first before sending 500 volts thru circuit .also these tests have to be performed with any switch neons disconnected and appliance disconnected. I'm sure your sparky knows this .

Thanks Jock. Hadn't heard of continuity test. 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?

If its an older house or flat is it the same colour of cable at cooker switch to that of consumer unit ie red black ,blue brown

Loose connection maybe .continuity could confirm this

Simply increasing size of mcb to 40 may make things worse.if it's say a 8 kw cooker then a 32 amp mcb would not trip the circuit .you can allow diversity to cookers .

Blue brown. Thanks for your help. I'll has the electrician

I gave him the make and model of cooker. He said the total amps was 35. That's why he changed from 32 to 40.

It would show weakness in the insulation ,the neutral or live could be hanging by a thread if something has damaged it

Total amps is 35 but you would normally allow for diversity .10 amps of total load plus 30 percent of remaining load.a 32 amp would normally work fine with that unless the cooker is being used to heat the room or being used all at once every time being used which is highly unlikely.is there a socket on cooker switch if so add another 5 amps on to calculation
