The purpose of an electrical panel is to distribute electrical power to different circuits in a building. This distribution is essential for ensuring that power is delivered safely and efficiently to various parts of a structure, allowing appliances, lighting, and other systems to function properly while maintaining safe operating conditions.

The electrical panel serves as a central hub where electricity from the utility company enters the building and is then divided into multiple circuits, each protected by a circuit breaker. This design helps to manage the load and protects the electrical system from overloads and faults by interrupting the flow of electricity when necessary. Proper distribution also allows for the addition of new circuits as the electrical needs of a building change over time.

Understanding the role of the electrical panel is fundamental for any electrical apprentice, as it is central to the safety and functionality of a building's electrical system.
