Was called to a commercial lighting issue on Friday where the circuit had tripped, RCBO protected.
On arrival reset the RCBO and all held, three lights weren't working, two were lamps and one had a black scorched ballast, replaced this and all works.
The circuit has eight lights, two PIRs a couple of fans on it from a quick look round and a handful of EM lights.
Only testing was a ramp and trip time on the RCBO, both fine.
Come today and its tripped again.
I'm thinking water ingress and a thorough all points visual inspection is required.
Finding and disconnecting all the points is a pain as some crettin has put a foot of isulation above the suspended ceiling. So IR testing is probably not time efficient plus, if the RCBO resets, the fault may not be there to find.
Are there any hints or tips for this kind of job or is it a case of doing the hard slog.
I'm working under the assumption the fault has cleared again so the normal route of splitting and IR is not going to cut it.
Cheers
