I posted this before but its worth airing I think. I did a few months with a large local contractor who tended to treat their staff like shytte .
This was the story I heard .
At the end of a new build supermarket project one of the sparks gets redundancy just after handover .
As the following year progressed the supermarket kept having a couple of rows of flush fluorescent lighting go out at different times . The firm kept sending guys back but the lights would usually be back on by the time they turned up .
They spent the whole installation guarantee year sending guys back , costing a small fortune . There was no logic to the lights going out or coming back on , supermarket not happy.
It was finally discovered that someone had wired in a time switch ,hidden in the false ceiling , the drive of which was connected to the switch wire of a store cupboard light ...obviously turned on & off all the time so it turned randomly and was switching the feeds to the two rows of lighting .
Before anyone dives in ...no it wasn't me .
