[left]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? [/left]

[left]I need some advice regarding my camper wiring. I just bought a camper a few days ago and it’s missing the plug that goes to the 30 amp outlet. I went to Home Depot and bought an rv plug thinking this would be super easy as it’s only 3 wires. The problem I’m having is that instead of a black, white and green/bare wire I have black, red and white wires. From what I understand black and red are usually hot wires and white is neutral. I really don’t want to wire this up wrong and short everything out. Any advice is much appreciated. Thank you. Trailer is marked as 120v / 30 amp[/left]
