A service entrance is the point where electrical power enters a building from the utility grid. It includes the service drop, which carries the power lines, and the meter that measures electricity usage. This entrance typically leads to a panel or circuit breaker system, which helps distribute electricity throughout the building. The service entrance is an important part of a building's electrical system, ensuring that power is safely delivered and monitored. It is usually located on the exterior of the building, often near the main electrical panel.
