What is the main function of circuit breakers in a load center?

The main function of circuit breakers in a load center is to protect against overloads. Circuit breakers are designed to automatically interrupt the electrical flow when the current exceeds a safe level, which prevents overheating and potential damage to the electrical system. This safety feature helps prevent electrical fires and protects connected devices from damage caused by excessive current.

While distributing electrical power is a function of the load center itself, circuit breakers specifically focus on protecting the system. Backup power concerns are typically addressed by separate systems, such as generators or UPS units. Regulating voltage levels is handled by other components like voltage regulators, not circuit breakers. Hence, the role of circuit breakers is firmly centered around safety and protection against overload conditions.
