Hey

so I am renting a large office space in NJ that used to be a school. The space is about 13k sq ft, with drop ceilings and there are fluorescent units throughout. I am slowly replacing all of the units with either pendant or led panels. What I’ve realized is that 98% of the wiring for these lights is run with bx cable that has the aluminum wire wrapped around the sheath. There is pretty much no ground wiring anywhere. Everything is above a drop ceiling and very few of the runs are hanging from the ceiling but instead resting on the drop ceiling. It’s an inherited nightmare. So I have a few questions, yesterday when I was swapping a few fluorescent units for led panels I noticed that the wiring closest to the panel did actually have a ground wire in the sheath but it stops at the second unit. So every unit after that is the ungrounded bx that I mentioned before. What should I do in this scenario? Do I need to continue running the ground to each unit independently or do I need to swap all of the wiring out for up to code AC or MC? Also in terms of the resting cables in the drop ceiling - I know it’s against code but it was installed that way and I just found it like that. Do I notify the landlord?

Hi Mate I have the latest NEC Code book but it strange to a Brit that isn't used to it, why not PM Megawatt, he is very clued up and is a fellow countryman, and a nice Bloke, sure he would be able to help. failing that wait for one of the US members to come on line and help

First off the lay in lights are supposed to be supported independently and the cables should be supported by bat wings. To my knowledge once you start you have to bring it up to today’s standards and MC cable is what you need. Good luck
