When round to a job yesterday where it is extremely damp. Tested light all ok and working. Now had a phone call to say since after heavy rain the lights are tripping intermittently. Says trips rcd and Mcb but resets fine. Has happened 3 times today. Any ideas of tops of heads before going Tomor morning. All feeds have been joined under floorboards etc and tested out and worked fine yest. But guys have been in with carpet cleaners and heavy rain today and now it's started.
Thanks
