This happened to me after the storm last Saturday. A limb was hanging vertically on 1 power line. I had always heard if an object touches more than 1 power line simultaneously, it would cause the line to trip off and there would be an outage. Not sure if that's true but I didn't want to take a chance. So I called Duke Energy Progress outage line....1-800-419-6356, option 2. They came and removed the limb
