Just finishing of a job,testing different circuits everything ok.
Testing ring main rcbo protected doing the usual test,soon as I switch tester on rcbo trips.
All the tests are ok,ie continuity ,insulation resistance & polarity tried another tester & this works fine.
The tested works ok on other circuits,but not on that specific one.
Any ideas.
