I actually took the ups out of the loop as the beeping was getting

It's still happening so it's not the UPS itself.


That tells you it is not the UPS. That doesn't tell you that only one
circuit is the problem.

If it doesn't show up on another circuit, I would put my money on
backstabs as someone else has already suggested.

If it does show up again then it is mostly likely the service.



Agreed, but.... could possibly be a problem with the load center panel
itself could it not? IE - corrosion on one of the bus bars....?


Yes. The load center commonly has aluminum wire. This is one of the
primary causes of a loose connection\corrosion.

I feel that because the OP has the UPS on only one circuit it caused
him to suspect that single circuit. I suggested that he plug the UPS
into another circuit as a test.

Switching the UPS would be an easy way to rule out either/or. If it
works properly on another circuit then he would know he was correct
and track down the problem on the single circuit.

If the UPS does show bad power on another circuit the cause would then
be most likely the service from his main panel back to the meter base.

The power company will check their connections at the meter base (for
free) and shut down the power so the OP could tightening his panel
connections.
