Multiple Choice

In an S-base meter installation, the top incoming lugs are typically ______.

Explanation:
Power flows from the utility through the line side, which is the top of a meter base. Those incoming lugs connect to the service conductors from the distribution system, so they carry the system’s voltage in normal operation. The bottom lugs are the load side that feeds the building, and they are energized only when the meter is in place and the circuit is closed. Because the top lugs are the source side, they are typically energized. Always treat the line side as live and verify before touching.
