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?
