Cooker install - RCCB tripping

[DarrellA]

Morning all,

I'm Having an issue with a cooker install and wonder if anyone can help.
Every time the cooker is switched on there is a RCCB trip (Rated at 80a 30Ma). The circuit will take a supply but no load of any kind. I connected a DeWalt charger to the socket on the cooker plate (only drawing 0.85a) and it still trips. The rest of the ring main/lighting circuit has no issues and tests with no problems.

Testing path -
Tested appliances, all good.
New cable run, thought it may be a neg earth fault due to a rogue screw/nail so replaced the cable again.
Removed all other connections in the distribution board so only the cooker was connected, same problem.
Swapped out the 40a breaker.
Swapped out the cooker connection plate.
All polarity & resistance checks out.

Scratching my head here, any help would be appreciated.

Thanks,
D​

Oh yes, lets change everything. RCCB, cable, cooker, isolation switch, etc
Probably there will be the same result.

What is needed is a change in the level of competence.

What a boring forum it would be if everyone knew everything. There would not be much debate would there?

What evidence do you have to make you not agree?

If the OP is to be taken of his word there is nothing left to be faulty.

I'm guessing but as this is a new circuit added, then we have to presume the RCD wasn't tripping before ............

In the absence of any meaningful test results we can only speculate.

The OP has gone notably quite, at work maybe?

He says the lighting and ring circuits which share the RCCB are working correctly without any tripping so it’s not likely to be the RCCB at fault.

essex's I'm getting really worried about you; you've gone too pink and fluffy. You need to go out to lunch with that German general bloke, might give you a few more rough edges again

The only time you run out of a bar is when you have the cash register under your arm............

Reminds me of a time I was out in Bath with a load of work mates, all out on the lash going round a few bars then off for something to eat. About to go into the sixth or seventh bar when I noticed my boot was undone, used the door step to rest on while doing up the lace. As I looked up there was a nice brass door sign "welcome to Mandalays Baths Premier Gay Bar" ! Super funny as they all filed out passed me calling me several names for not telling them. Truth is I just stopped to do up my shoe ! The bar man, fair play to him had checked they where in the right pub before taking the beer orders.

I've heard you run to the toilet when you realise you're at the front of the queue to buy the next round. You know short arms long pockets
