I recently got a service call that lights were dimming in the home in the evening. They will actually dim like a dimmer switch for 10-20 seconds then go back to normal. They also go out at times. I asked if it was just a certain room, and was told it was all over the home. I check the main breaker and all the neutrals and everthing is tight. The local power company check the pole and weatherhead and said everything is fine. I am meeting with them to have them take out the meter so that we can check the terminals inside to see if anything is loose. I feel the problem is at the post and beyond and the power company should place a meter on this to look for a problem. Anyone got any ideas!!
