Need advice. I'm replacing a fluorescent light with 4 wafers. I've drilled the holes and pulled the 12/2 wire. I took the fluorescent down and there is no ground. The wire is in metal conduit and I read on another thread that I can attach the 12/2 ground to the metal conduit. I assume it's grounded but I'm in a condo with no access to the attic. I can only see from the holes I've made. How do you attach a ground to the conduit if that is the solution. The date on the fuse box is 1969. -- Thanks

Conduit makes that a tough job. You need a box at the end of the conduit to convert from individual wires to nm-b cable. The easiest way to accomplish what you need to do is to leave that box just as it is. Take a knockout out and connect your NM-b directly into the box. There is a small hole that will take a ground screw and that's where the ground gets connected. You can use a canopy blank over that box as it will need to remain accessible.

Thanks Paul. I was able to detach it from the ceiling supports and pull the new wire. I'll run up to Home Depot for a cover plate. Not sure if I have a screw with me for the ground wire, but I'll get one if I don't. I'm doing this at my son's condo several hundred miles from my home. I really appreciate your quick reply.

Before you do this work you need to verify whether (quite often) electrical work in a multifamily building (beyond installing a nicer light fixture in the same place or replacing a broken receptacle) has to be done by a licensed professional.S/he would determine whether the existing conduit is a good and sufficient equipment grounding conductor and if it is not, run a separate EGC after the fact..

 

It's a little late now Allan...... it looks like all the holes are cut and wire is run.
That EMT is considered an acceptable ground.

 

Thanks for all the replies. They were very helpful.
