strange set up

12 14Ft 175W MH pole lights were contolled by this timeclock..which was way in the back of the parking lot. It sounds like no one was aware so the clock was messed up for a few years and the lights just came on randomly, no one caught the issue but I did! I gave WG EMS a call and they said their remote breakers in the pannel were all communicating and working, so he said it might be a bad contact in breaker, long story short I replaced the timeclock with a photocell, the rest of the building lights are EMS controlled though
