Ok so i have a conundrum i'm hoping you can help with. My issue starts and finish's with heavy rain, sometimes when it rains my main rcd in consumer box trips (not all the time, just sometimes), I feel this is to do with the outdoor spur (maybe a nick in a cable - although it is armored...) as when i disconnected this i didn't see any issues (a few weeks loads of rain etc). I have now reconnected it and Kalamazoo rain tonight and the power has died.
So that's the background, here's a little bit more info - the outside unit is connected to a 25a, 30ma rcd (ip67 outdoor housing), i have replaced RCD last week so can exclude that as an issue, the earth is passed through, when the power trips only the rcd in the indoor consumer unit trips, not the outdoor one and this is the perplexing bit - as if it is the outdoor spur, why isn't the outdoor rcd tripping?.
My initial thoughts is that it is as the earth is passed through so detected at source first?, as such should i disconnect the earth pass through and create a seperate earth (unsure how to do this, but will google it!)?.
Any thoughts/suggestions on trouble shooting or other input greatly appreciated.
Thanks
