Breaker box
A breaker box, also known as a circuit breaker panel or fuse box, is an electrical panel that contains circuit breakers or fuses that protect electrical circuits in a building or home. Its primary function is to distribute electricity from the main electrical service panel to various parts of the building, while also providing a safe and controlled way to shut off power to individual circuits in case of an electrical emergency or fault.
Here are some key features and functions of a breaker box:
- Circuit breakers or fuses: The breaker box contains a series of circuit breakers or fuses that are designed to interrupt the flow of electricity in case of an overload or short circuit.
- Circuit identification: Each circuit is labeled with a number or description, making it easy to identify which circuit is which.
- Main electrical service panel: The breaker box is typically connected to the main electrical service panel, which receives electricity from the utility company.
- Power distribution: The breaker box distributes electricity to various parts of the building, such as lighting, outlets, and appliances.
- Safety features: Breaker boxes often have safety features such as ground fault circuit interrupters (GFCIs) and arc fault circuit interrupters (AFCIs) to prevent electrical shocks and fires.
- Maintenance and repair: The breaker box can be easily accessed for maintenance and repair, allowing electricians to diagnose and fix electrical issues quickly and safely.
Types of breaker boxes:
- Main breaker box: This is the primary breaker box that receives electricity from the utility company and distributes it to the rest of the building.
- Sub-panel: A sub-panel is a smaller breaker box that is connected to the main breaker box and provides additional power to a specific area of the building.
- Load center: A load center is a type of breaker box that is designed for residential or commercial applications and provides a central location for distributing electricity.
Overall, a breaker box is an essential component of any electrical system, providing a safe and controlled way to distribute electricity and protect against electrical hazards.
