Where should meter sockets and meter disconnect switches be connected relative to a service disconnecting means?

Meter sockets and meter disconnect switches should be connected on the line side of the service disconnecting means to ensure proper operation and safety. The line side refers to the portion of the electrical system that carries power from the utility to the service panel. By connecting on the line side, the meter and the disconnect switch are positioned before the main service disconnect, allowing them to accurately measure the incoming electricity from the grid before any usage or distribution occurs within the building.

This configuration is essential for both safety and functionality. It allows for appropriate measurement of the total energy used and isolates the meter from the load, ensuring that maintenance can be performed without affecting service to the entire building. Additionally, in cases of power interruption or maintenance, having the meter and disconnect above the service disconnect helps to ensure that no backfeed occurs which could pose a risk to utility workers or compromise the integrity of the electrical system.
