What Is a Meter Socket?
A meter socket is an electrical fitting that holds an electric meter and connects it to the service wiring. The socket sits inside a meter box, usually on an outside wall. Its metal contacts connect the meter to the path that carries electricity from the utility to the building.

How Meter Socket Works
A meter socket connects the utility supply to a building's electrical service through the meter. Supply wires enter the socket, and contacts hold the meter in place. Wires leaving the socket carry power toward the building's electrical panel. Related service: Meter Socket Replacement.

The electric meter measures electricity use as power passes through its connections. The socket provides those connections, but it doesn't measure the electricity itself. The utility uses the meter reading to track energy use.
The socket's enclosure protects its connections from exposure. A cover surrounds the meter opening, while the meter face remains visible. The design of the enclosure and socket depends on the service equipment and where it's installed.

When we replace a meter socket, we check how the existing service wires enter the enclosure. We also check that the replacement fits the service equipment and the meter connection. The utility's role in disconnecting and restoring service shapes how we plan the work.
