In my study, my lamps will flicker every few minutes or so. I assume that
I have some defect in the wiring on this circuit, or that there is a problem
with my circuit breaker connection, or the breaker itself.

So, today I went to the breaker box and made sure that the wire connecting
to the breaker were screwed down as tight as possible. I was able to turn
the screw a full 1/2 turn, so I thought this might have cured the problem.
But, it didn't.

This is a 15 amp, 120 volt circuit, and breaker. Is it very likely that
the breaker itself is bad, or may I have a wiring problem somewhere in this
circuit ? As far as I know, it provides power to just my one room study.

I can tell that when I turn on a heavy-current device such as my fax
machine, these lights will flicker when the machine operates. So, the
flicker can be triggered with a heavy load. I have never noticed this
before. But be aware that I get frequent flickering even when there is no
extra heavy load.

The house is 30 years old, and most likely, it is the original breaker.

Any advice would be appreciated.

Thank you.
