Then the tails to the seperate flats are wired in 16mm T&E which I absolutely hate as the earthing conductor is not sufficient in my opinion.
Thoughts?
In a commercial premises, I was called to recently, the power had tripped off. It turned out it was a SON lamp which was causing the problem. This tripped the 30mA RCBO for the lights and also the main 30mA RCCB below DB 3, which in turn meant other essential circuits i.e. chilled food cabinets...
