What is an electrical service drop?

Thursday, December 2, 2021

A "service drop" is the set of overhead wires running from an electric utility’s pole to a house or other building. The service drop is installed and maintained by the local electrical utility. It is connected at the “service point” (shown at arrow in photo above) to the “service conductors” that run to the “service panel,” usually through a “service mast” that extends above the roof. All wiring and other electrical components past the service point are the responsibility of the building owner. When the wires come to the building underground, it is called a "service lateral."
