I was at a commercial property at weekend and one of the issues to look at was intermittent RCBO tripping for a ring which feeds ladies and gents washrooms and the coridor.
Coridor has 2 SSSO's and each washroom has a DSSO and 3 FCU's for: shaver socket, hand drier and hairdryer.
This
was the problem.
To the right of the socket is one more tile and the skirting stops, and the floor level drops by 50mm or so, the next 1100mm is classed as wet room with 3 shower heads on the wall at right angles. The water marks are just visible on the skirting and the brown gundge behind the child proof cover was giving a reading of 14KΩ. The RCBO tripped within a minute of running the nearest shower and watching the water splash up off the floor.
Luckily the singles dropped from the suspended ceiling in conduit and this was easily altered to do away with the socket.
