Circuit breakers and fuses are safety devices that you'll find in your electrical panel. They serve a similar purpose ”preventing electrical overload” but operate differently. Circuit breakers are switch-like mechanisms that can be reset if they trip due to an overload. On the other hand, a fuse contains a metal wire that melts when overheated by excessive current, thereby interrupting the flow of electricity. You will need to replace a fuse once it blows, unlike a circuit breaker, which simply needs to be reset.

Amperage Rating and Number of Circuits

The amperage rating indicates the maximum current that can safely pass through the electrical panel without causing damage or posing a hazard. Each circuit breaker or fuse within the panel will have an individual amperage rating, showing its capacity to handle electrical load. The number of circuits in your panel is also important; this refers to the individual electrical paths within your home. Most residential panels are designed to accommodate multiple circuits, ensuring different areas and appliances receive power independently to avoid overloading a single circuit.
