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​

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

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.

Sooooo outside a gay bar bent over pretending to tie up your boot laces......... and you think we'll believe that one......

If there was an award for a thread veering so far from the OP surely this is it? Ha ha ha

The test first would have been better to eliminate a cable fault !!! Have you charged someone for the time of doing this??

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.

Sounds OK now.....he must have had a read of the thread.

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

Nonsense, Polish always get overrun by everyone, just look back in time

Solved: After lengthy testing it was a faulty Cooker switch that was causing it. Thanks for the help, even if it went off at an absurd tangent

Glad you have sorted it Darrell. That should have shown up on your tests though.

Try a load at the switch socket with the cooker disconnected..
