Can a telephone pole shock you?

Birds are able to sit on electrical power lines because the electrical current essentially ignores the bird’s presence and continues to travel through the wire instead of through the bird’s body. A bird’s body is not a good conductor of electricity.
Why can a bird sit on a power line?
Birds sitting on a wire don’t touch the ground (or anything in contact with the ground), so electricity stays in the power line. But, if a bird touches a power line and equipment or other metal that is grounded, it gives electricity a path to the ground, and the bird could be shocked.
What happens if a telephone pole falls?
If they lean too much, they may crack and break off, causing the transformer to come crashing to the ground. Power Lines – if the utility poles fall, they bring power lines with them. These power lines typically carry between 4 to 25 kilovolts, enough to cause severe injuries or even death.
