[COLOR="Black"][/COLOR]I have a contractor finishing out a somewhat large room in my basement. It is going to be used for a gym and we've decided to make the lighting very bright, but put it on a dimmer. Currently he has 22 can lights in the ceiling and we were going to run this on one dimmer switch. a few questions: 1) If we use 45 watt or 90 watt bulbs (or whatever you usually use in a can light) how many fixtures can be used safely in this situation? 2) Does this need a dedicated circuit? how many amps?

Today half of one of my home's circuits stopped working. At first I thought it was the breaker, so I put a new one in. It was then I realized that some of the items on that circuit were working, and others were not. I did have some workers operating some heavy tools at my house, initially I thought that the circuit was overloaded(?), or something burned out (is that possible?)... I can't figure what it might be, but my new line of thinking is that the vibrations of the equipment they were using shook loose a connection somewhere... any ideas on how to trace this problem out?? Any help would be so appreciated.
