Earth leakage trip 7 min past the hour every hour. How do I locate the problem? This started after I replaced the old Earth leakage. Driving me mad. The problem is on one of about 7 circuit breakers or combination of them. This tends to happen only at night, but does happen here and there during day hours.

Maybe disable the timer switch....
Meant as a joke, but it seems there may be sense in the madness?

Do you have any surge protection plugs?
If your geyser is fed via the ELCB, remove it. Just make sure it has good earthing because this could be the beginning of the end of your element.
The geysers have no effect on the tripping of the ELCB. Neither the lights. Just the plugs. It seems to be random, or building up something, that makes it trip in exactly 60 min at night! Exactly 7 min past the hour!

I had this problem about a year ago. In the end, I have put the old earth leakage unit back. I forgot about it and replaced it now again. So this condition is around for a long time now. Only timer around, is the one at the pool pump.
Why would it be hourly at night and only once or twice during the day?

Hi there! if your ELCB trips every 1hour 7min, then switch your CB's off - one by one for 2-3 hours each.
This will take long but will eventually locate your culprit.
This is what I am doing. What makes it difficult, I cannot do it during the day, as I can leave all the ELB's on during the day and nothing will trip. I left everything on today again, the whole day and had my first trip at 18h07.Originally Posted by SihleN
I have figured out, it is at night, with 6 breakers switched off, that I do not get trip's. However, if I go on any combination, smaller than these 6, I get trips.
Yes, it is a CBI. But it is the second brand new one. The first was a 63amp 3ka, the second new one is 63amp 6ka.
I am still testing....

If you have had lightning or power surges recently, the caps could be faulty, you reset and there is no problem, but it will normally just trip randomly, not ever hour, but you never know, i have seen stranger thing happen.
It wouldnt be a CBI earth leakage unit by any chance?
