What is a Circuit Breaker Box?

A circuit breaker box, also known as an electrical panel or distribution board, is the heart of your home's electrical system. It acts as a central hub that allows electricity to flow safely throughout your property. Circuit breaker boxes are responsible for controlling and protecting electrical circuits, preventing overloads and electrical hazards.

The Purpose of Circuit Breaker Boxes

Circuit breaker boxes serve several crucial purposes:

  • 1. Protection: Circuit breaker boxes protect your home from electrical fires caused by overloads or short circuits.
  • 2. Power distribution: They divide electrical power into different circuits, ensuring a balanced and safe distribution of electricity within your home.
  • 3. Easy maintenance: Circuit breakers allow for easy isolation of specific circuits when repairs or maintenance work is necessary.

Types of Circuit Breaker Boxes

There are various types of circuit breaker boxes available, including:

  • 1. Main Breaker Panels: These boxes have a built-in main breaker switch that allows you to shut off power to your entire house.
  • 2. Subpanels: Subpanels are smaller breaker boxes installed in different areas of your home and are connected to the main breaker panel.
  • 3. Fuse Boxes: Although less common nowadays, some older homes may still have a fuse box instead of a circuit breaker box.

Installing a Circuit Breaker Box

The installation of a circuit breaker box should always be performed by licensed electricians like our team at Walls Electrical. They have the necessary knowledge, expertise, and tools to ensure a safe and compliant installation process.

Maintaining Your Circuit Breaker Box

Regular maintenance is important to keep your circuit breaker box in optimal condition. Here are some essential maintenance tips:

  • 1. Keep it clean: Regularly inspect and clean the circuit breaker box, removing any dust or debris that might accumulate.
  • 2. Test your breakers: Periodically test your circuit breakers to ensure they trip as intended. Contact a professional if you encounter any issues.
  • 3. Check for signs of damage: Look out for signs of wear, such as discolored or corroded breakers, buzzing sounds, or burning smells. If you notice anything unusual, contact a qualified electrician immediately.


Circuit breaker boxes are a vital component of your home's electrical system, ensuring safety, distribution, and protection against electrical hazards.
