New cooker tripping RCD

[Toneyz]

Surely instead of all or nothing approach, why not a mix of MCB's and RCBO's as appropriate? But the sum total of leakage is a concern

1. The OP has already got the consumer unit fitted and would be a waste of money spent.
2. I don't think the OP has the room for a split consumer unit.

Wow, catching up on all that was interesting

Quick update: All MCB's have now been replaced with RCBO's and I've had no issues since. Granted, I've had the cooker replaced since then but it's very unlikely that was causing the issue.

In response to the "why buy an earth leakage tester?" question. I'm just a very technical person with an interest in almost everything. I wanted to narrow down the problem myself. I'm not saying I'm qualified to do what most people do on these forums, but I've learned some things and that's better than when I originally posted the question. Totally unrelated, there's a cheap earth leakage tester on eBay if anyone is interested

Search earth leakage tester and scroll down until you see the red second hand one that is currently around 32 quid. And then click the agree icon

similar to the cheapo i got.poor resolution and prone to giving erratic readings. jaws won't clamp 2 x 25mm tails, but a useful tool in conjunction with MFT , common sense, and scribes on a beermat.

I have a Fluke 360 earth leakage current clamp and it is very accurate right down to I micro amp, which subtends to 240 Mohms insulation resistance.
