The most common issues we find with overhead powerlines during home inspections are trees rubbing up against them and exposed connectors that present an immediate shock or electrocution hazard. When we find either one of these conditions, we recommend repair. The question that always follows is "Who's responsible for that?"

Tree Branches
According to Xcel Energy, tree branches in contact with the overhead powerlines between the pole and house are the responsibility of the homeowner. Of course, this is only fair. Tree maintenance should be the responsibility of the homeowner, not the power company. Before trimming trees around overhead powerlines, you should contact the power company to have your service temporarily disconnected.

Trees Rubbing on Wires
The one exception is if a tree branch falls onto one of the overhead powerlines. If this happens, it's considered an immediate safety hazard. Xcel Energy will take care of this issue at no charge to the owner.
Exposed connectors
The power company owns the overhead conductors and the clamps that connect them. The diagram below shows the parts that are owned by the utility company and the parts that are owned by the homeowner.

And this annotated image below, courtesy of Xcel Energy, shows the same thing:

The photos below all came from houses that we've inspected where there were exposed connectors, which connect the utility lines to the house.
