HAAG Certified Reviewer Practice Exam 2025 – Complete Study Guide

The meter base serves as the connection point between the utility company's power line and the structure. It is where the incoming electricity is measured before it enters the building's electrical system. The meter allows the utility company to track electricity usage for billing purposes, making it a critical component in the overall electrical infrastructure.

The meter base is typically installed on the exterior of the building and connects directly to the service entrance, which is the point where the utility lines enter the structure. This ensures that all power usage is accounted for before it is distributed throughout the building's electrical system.

In contrast, while the service entrance and breaker panel are important components of an electrical system, they do not serve as the direct connection to the utility company's lines. The distribution board is also part of the internal electrical distribution but not the direct interface with the utility supply. The meter base uniquely combines the functions of connection and measurement, making it the correct answer in this context.
