Hello all,
I have recently attended a job where a row of lights have gone out and was advised and seen for myself when i got there that no breakers have tripped.
First i took the cover off of the panel with the mcb's that feed all lighting circuits in open office area , and checked i have 230v on load side on mcb , which i did have on all mcbs to rule out a faulty breaker. I next went to the nearest light fitting to the riser where dbs where and found 230v at fittings with lights not working (all on sensors ) and ballast units also had 230v.
I then was advised (by site engineer) that sometime in the past these lights had lost power and had been rewired by someone ?? not sure if they were qualified or not ... i then went to a room at the end of the office area where he advised me they repowered this lighting circuit which has now gone out but power still there couldn't see any polarity faults but didn't get a chance to check all fittings as was in working hours of a office.
At the end fitting i was getting 230v between N-E and i haven't come across this before would appreciate any help
