A breaker box, also known as an electrical panel or circuit breaker panel, is the central hub for distributing electricity throughout a building. It houses circuit breakers, which act as safety devices that shut off power in case of electrical overloads or faults.
Key Components of a Breaker Box
- Main Breaker: Controls the overall power supply to the building.
- Circuit Breakers: Individual switches that regulate electricity flow to different circuits.
- Bus Bars: Conduct electricity from the main breaker to the individual circuit breakers.
- Neutral & Grounding Bars: Provide safe pathways for excess electricity.
Types of Breaker Boxes
- Main Breaker Panel: Includes a built-in main breaker to shut off power to the entire system.
- Sub-Panel: A smaller panel used to distribute power to specific areas.
- Transfer Switch Panel: Used for backup power sources like generators.
