Evening all.
Had a call out earlier to a caravan park. The RCD's on various hookups trip during heavy rain. Checked enclosures, they are reasonably new, no moisture etc. They are all fed via a 16mm 3 core SWA. Main DB MET is connected to an earth rod (TT) which is in good condition. Tested a few hookups. All RCD tests fine. 112 ohms was the highest reading.
The site has had a new 3 phase supply installed recently and they believe the RCD's have only being tripping since then.
If anyone can point me in the right direction on this one it would be much appreciated.
Cheers
