The AC outlet in my ceiling above where my chandelier hangs is going bad. I need to replace it. But I can't get to it! The mounting bar that supports my chandelier blocks me from getting to it. It's a small space. The geniuses that designed this made it so I can't just unscrew the mounting bar either. It's pretty much fixed in there. Seems ridiculous to have to tear parts of my ceiling out just to replace a little AC outlet. It seems even more ridiculous to give up and settle with a chandelier that I can't use. There must be an easier way around this. Any suggestions?
From your photo and your description it is still not clear (to me) what is going on.
You stated "The AC outlet in my ceiling above where my chandelier hangs is going bad. I need to replace it. "
From the photo, I can see two "figure 8" pairs - one white and one clear - plus a bare copper earth wire going somewhere, but these do not appear to be going to that which you describe as "The AC Outlet". ( Is this [cylindrical] "AC outlet" an Edison screw socket and is it in use - since a bare copper earth wire could not connect to such a fitting? )
I gather that the chandelier is mounted on a threaded tube which is fixed by two (?) screws (one of which is NOT shown in the photo) to a metal support above it. While it is not clear how or if the support above is fixed in place or how it might be removed, would not removing the two screws allow the threaded tube and its "base" to be slid forwards or back and the fitting lowered to the ground - pulling out the two pairs and earth in the process.
(It is almost certain that you would need the assistance of another person for this procedure.)
Somewhere, those wires must connect to the wiring of the premises and I suspect that, when these wires are extracted from the ceiling - which you should be able to do without removing the chandelier, you may find several connectors (wire nuts ?)
In addition (as a "plug" for an organisation with which I have no connection) I draw your attention to a UK made "Maestro Plug-in Ceiling Rose", made by Lewden in that country. They are rated at 230 V, 6 A and, hence, should "pass muster" in North America - Maximum weight is 5 kg (11 pounds)
I have two of these and they enable the chandeliers concerned to be taken down for cleaning (when required) and "plugged" back in without disturbing any wiring.
