I was at a club that I'm a member of investigating a tripping RCD.
One of the circuits that the RCD protects is a sub main to another CU. I tracked the fault down to a lighting circuit which supplies the kitchenette and gents.
On taking a cover off a 2D fitting I had to empty it immediately into the loo,,, it was full to the brim with water:O
Now obviously the fault is the leaky roof which is letting water in if it's raining from a particular direction..,,,, my remedy was to add a DP isolator at the supply and replace the affected 2D fittings with batten holders, whilst not the ideal solution IMHO it is the best I can do until the roof is repaired
