Dimming Light, etc.
We have a vacation cabin that just started having this problem. Some lights will go dim and the ceiling fan will buzz occasionally. There's no rhyme or reason as to when this happens, but when it does it cycles several times then will go back to normal. It seems to happen when the refrig or well pump kicked on, but not always. Sometimes some lights will go completely out a brief moment while others stay on. I looked at the breaker panel thinking they might be circuits all on one side, but it happens to circuits on boths sides at the same time while others are okay. What is going on and could it be on the power company's equipment?
