I had the garage upgraded to 100 amps. The guys did a great job. I'm having another problem, but I didn't mention it to them until yesterday, and they didn't have much time to take a look. The problem is some of the lights in my house seem to dim ocassionally. This was happening before the garage work was done, so I doubt it has anything to do with it. When they dim, sometimes the computer shuts down, (it is on a surge protector), the clock on the range resets and so forth. My home is thirty-two years old, and has aluminum wiring. (Lucky me). I had a similiar problem a few years ago and an electrician from the power company opened up the meter tightened the lugs inside, (said it "single-phasing"?) and the problem went away. I thought maybe my problem was a bad circuit breaker, but not all of these items are on the same circuit. Does it sound like single-phasing? And if so, what can be done to keep them tight? Thanks folks!

I had the cover off the breaker box and noticed an arc from behind the 200amp main breaker. I tightened the lugs on the breaker, and every screw in the box. After I turned the power back on, I saw a small arc from behind the main breaker when the heater came on. It's a Murray box and breaker, both around 30 years old. So does it sound like the trouble is in the breaker to you guys? And are breakers that old still available?
Thanks for all the help...
