The Differences Between a Breaker Box & an Electrical Panel

When it comes to your home’s electrical system, two terms that often come up are “circuit breaker box” and “electrical panel.” Although many people use these terms interchangeably, they actually refer to different components of your electrical system. Understanding the differences between the two can help you better manage your home’s power supply and ensure electrical safety.

In this blog post, our electricians at Ostrom Electrical Plumbing Heating & Air break down what each of these is, how they work, and why knowing the distinction matters.

What Is a Circuit Breaker Box?

A circuit breaker box, which is also often called just a breaker box, is the central point in your home where electrical circuits branch off to deliver power to different parts of your house. The main job of the circuit breaker box is to protect the wiring in your home from electrical overloads, which could cause fires. Each circuit in the box is protected by a circuit breaker, which is essentially a switch that automatically shuts off the electrical flow if it detects a problem, such as an overload or a short circuit. In most homes, the breaker box is located in a garage, basement, or utility room and can be easily accessed if a circuit needs to be reset.

Features of a Breaker Box

Breaker boxes comprise of various components to meet the following functions:

• Circuit protection: Each breaker is designed to prevent overheating and potential electrical fires by shutting off when too much current flows through the circuit.
• Control of circuits: You can manually switch off breakers to stop the electrical flow to a specific part of your home, which is useful during repairs or emergencies.
• Safety measures: Modern circuit breaker boxes are equipped with advanced protection mechanisms, such as ground fault circuit interrupters (GFCIs) and arc fault circuit interrupters (AFCIs), which help prevent electrical shocks and fires.

What Is an Electrical Panel?

An electrical panel is a broader term that encompasses more than just the circuit breakers. It refers to the entire enclosure that houses not only the breakers but also the main service disconnect, wiring, and any additional components necessary to manage the electrical load for your home.

The main panel is where the utility company’s power enters your home. It serves as the hub for all electrical circuits. Some homes also have subpanels, which are smaller electrical panels that distribute power to specific areas like garages, basements, or outdoor spaces.

Features of an Electrical Panel

Your electrical panel is responsible for the following:

• Main service disconnect: This is the large switch located at the top of the panel that shuts off power to the entire house. It’s a crucial safety feature that allows you to cut power in case of emergencies or when major electrical work is needed.
• Housing for components: The electrical panel contains not only the breakers but also all the necessary wiring, bus bars, and other components that distribute power throughout your home.
• Power distribution: While the circuit breakers manage individual circuits, the electrical panel ensures that the power is properly distributed to all parts of your home without overloading the system.

Differences Between Circuit Breaker Boxes & Electrical Panels

While the circuit breaker box is a crucial part of the electrical panel, it’s not the same thing. Here’s a breakdown of their differences:

• Functionality: The breaker box focuses primarily on protecting individual circuits, while the electrical panel handles the overall distribution of power and contains additional components like the main service disconnect.
• Components: A breaker box holds circuit breakers, but the electrical panel also includes bus bars, wiring, and other essential parts for power distribution.
• Scope: The term electrical panel refers to the entire enclosure that controls and distributes power throughout your home. The circuit breaker box, on the other hand, refers specifically to the breakers within the panel.

Why Does It Matter?

Knowing the difference between a circuit breaker box and an electrical panel is important for both safety and maintenance. If you’re dealing with a tripped circuit or need to turn off power for electrical work, you’ll likely interact with the circuit breaker box. However, if there’s a need for significant electrical upgrades or repairs, an electrician will work with the entire electrical panel.
