We have a large buidling that we keep lights on year long. They went to turn on and WOW! Yesterday and now tonight they called and said only have the roof and the back half of building is lite. Now what? What we did - the gutters in front, which ran up the front peek, then across the rigde, turned around and did ridge on back side, down the front peek, back gutters, up the back peek, down the back peek, that is where our power is coming from. I dont understand when we turn them on the other day everything was good. Three days later were only running half.
