  • When a tree's branches are touching a power line, how come

    Answer (1 of 10): First of all, just because the wires are touching the branches doesn't mean they are connecting to the branches since some power line wires, such as those coming to your home, are insulated. Of course if the wires rub against the branches, the insulation can rub away and then t
