Which components must be included in a Service Entrance?

A service entrance is defined as the point at which electrical power enters a building or structure, and it is critical to ensure that it includes all necessary components for safe and effective operation. The correct answer highlights that service conductors, disconnects, and meters must all be part of a service entrance.

Service conductors are essential as they carry the electrical current from the utility supply to the building's main electrical panel. These conductors are responsible for providing the necessary voltage and current to the electrical system of the facility.

Disconnects are equally important because they provide a means to safely shut off the electrical supply to the building. This is crucial for maintenance, emergencies, or when work is being performed on the electrical system. The availability of a disconnect is a safety requirement and is mandated by the National Electrical Code (NEC).

Meters are included in the service entrance components to measure the amount of electricity consumed. They provide essential data for billing and can help in monitoring power usage, ensuring that the building's energy consumption can be tracked and effectively managed.

Compared to other choices, options that suggest only disconnects and meters or only service conductors and circuit breakers do not provide a complete picture of what constitutes a proper service entrance. The combination of service conductors, disconnect
