I installed a 3 way dimmer switch and it works beautifully. I had, of course, turned off the breaker before I worked. Later I turned the breaker back on and the dimmer worked great. One problem though, the particular breaker controls the garage lights, utility room lights, dining room, entrance hall and outside lights. The dining, garage, and utility room lights work great, but there is no power to the entrance hall or outside lighting. What did I do wrong. Help!
