What is the primary purpose of a service panel?

1. To monitor energy consumption

2. To convert AC to DC voltage

3. To distribute electricity and protect circuits

4. To increase the voltage supplied to appliances

The correct answer is: To distribute electricity and protect circuits

The primary purpose of a service panel is to distribute electricity and protect circuits. The service panel, often referred to as a breaker box or electrical panel, serves as the main hub for electrical distribution in a building. It receives electrical power from the utility company and distributes it to various circuits throughout the premises. The panel contains circuit breakers or fuses that protect the electrical circuits by tripping or blowing when there is an overload or a fault, preventing potential hazards such as electrical fires or damaged appliances. This distribution and protection ensure that electricity is delivered safely and effectively to various electrical devices and outlets. While monitoring energy consumption, converting AC to DC voltage, and increasing voltage supplied to appliances are tasks related to electrical systems, they do not represent the primary function of the service panel. The panel's main role is centered around the safe distribution of electricity and circuit protection.
