RCD's tripping

Had similar problem and it turned out to be dodgy Neutral connection in supply switch gear.

Where they tripping during heavy rain? How did you go about rectifying the issue?

Cheers.

Rain not an issue with that case, re-terminated bad N connection to rectify.

If this an overhead supply then weather can be involved if its a dodgy N up the pole.

Has any one noticed flicker on supply?

Would suggest check all terminations back up stream to supply point and Test L-N Loop at all DBs

If suspect supply then call in DNO to check up the pole(s)
