RE: "Lighting is always on a seperate circuit from power here, and uses much thinner cable (1 or 1.5mm) and a much lower fuse/breaker rating (6A, usually). I don't know what your cable gauges are, but 1mm is rated for 14A, 1.5mm is 18A and 2.5mm is 26A. There's also 4mm and 6mm for special purposes, but I can't remember their ratings." My workshop lighting circuit is shared with a basement pump and the freezer. I want to know as soon as possible that we have tripped a breaker on either. That is not what the building code wants, but it is the simplest solution for an alarm that I could think of.
