What is the purpose of fuses and circuit breakers in generators?

Fuses and circuit breakers serve a pivotal role in protecting electrical systems, including generators, from damage caused by electrical overloads. Their primary function is to interrupt the flow of electricity when current levels exceed safe thresholds, which can happen due to various reasons such as short circuits or equipment malfunction. This interruption prevents potential overheating, fire hazards, and permanent damage to generator circuits or connected devices.

When excessive current flows through a circuit, a fuse will melt and disconnect the circuit, while a circuit breaker will trip, stopping the current flow. These devices act as safety mechanisms that safeguard both the generator and any connected equipment, ensuring that the system operates within safe parameters.

In contrast, enhancing power output or regulating voltage levels is not the main function of these safety devices, and they do not measure energy consumption. Their core purpose is focused on safety by preventing overload situations that could lead to catastrophic failures.
