What devices can protect generators against overload?

Fuses and circuit breakers are essential components for protecting generators against overloads. They work by interrupting the electrical flow when a circuit becomes overloaded, which helps prevent damage to the generator itself and the connected equipment. When the current exceeds a predetermined limit, a fuse will blow, while a circuit breaker will automatically trip, cutting off the power and preventing overheating or electrical fires. This protective mechanism is critical in ensuring the longevity and reliable operation of the generator under varying load conditions.

Temperature gauges, while useful for monitoring the operating temperature of the generator, do not actively prevent overload situations. Voltage regulators help maintain the output voltage within specified limits but do not serve as overload protection devices. Battery chargers are important for maintaining battery levels but are unrelated to managing generator load issues. Therefore, fuses and circuit breakers are the specific devices designed for overload protection.
