At my business, it appears a lighting circuit has failed.
What happened was all the power tripped in one section of the building. I went to the RCD, I saw that the section was tripped and restored it. All the power came back on. Less than a minute later, the lights went off. I checked the RCD and nothing is tripped. Any suggestions? This happened about 2 months ago, and it just fixed itself.
I don't know why, but to turn those lights on and off, we have to use one of those emergency lighting keys (that look like a 'tuning fork').
