Hey guys
Got called to a job where the entire installation was fed above a suspended ceiling on a commercial premises wired a few years earlier. All the cables are draped across the ceiling grids, all light fittings not double insulated and made off poorly with the possibility for the grid to become live, all lights wired in a spaghetti junction on cabling, circuits overloaded and switched on caused mcbs to trip out in the mornings. No proper design whatsoever...was a complete mess. plus the grid wasn't earthed either...
I'm going to be ripping the lot out and starting again properly and doing the work via contactors. what system would you guys do? I was thinking of doing the work in plastic conduit in singles going to a few 10 way Klik outlet lighting distribution boxes then flexing off to the LED ceiling panels.
One issue I do have though, there is a fire alarm panel but all the alarms/sounders are located above the suspended ceiling grid. What actually happens with this? Its not a job I personally deal with but is this common? Its pretty redundant having all the sounders and detectors left above the ceiling, there is also no fire alarm call points either (smash the glass ones).
There is no emergency lighting in the building at all also which I cant get my head around, I will be doing this also.
Cheers guys
