What is the main function of a service panel in an electrical system?

• A. To measure electrical consumption
• B. To distribute electricity to various circuits and provide circuit protection
• C. To transform electrical currents
• D. To connect external power sources

Answer: (B)

The main function of a service panel in an electrical system is to distribute electricity to various circuits throughout a building and provide circuit protection. This panel, often referred to as a breaker box or main panel, serves as the central point where the electrical supply from the utility company enters the premises. It contains circuit breakers or fuses which ensure that if a circuit becomes overloaded, the circuit breaker will trip or the fuse will blow, thus protecting the wiring and reducing the risk of fire. In addition, the service panel organizes and routes the electrical power to different circuits for lighting, appliances, and outlets, ensuring that each of these receives the appropriate amount of electricity to function safely and effectively. This role is critical for maintaining safety and efficiency in the electrical system as it manages the distribution and protection of electricity.
