A circuit is typically protected from overload by using fuses or circuit breakers. These devices are essential safety components in electrical systems. Fuses work by melting a conductive link when the current exceeds a specified limit, thereby interrupting the circuit and preventing excessive heat buildup and potential fire hazards. Circuit breakers, on the other hand, can be reset after they trip due to an overload, which provides an added convenience while still offering robust protection against electrical faults. By interrupting the current flow during an overload condition, these protective devices safeguard both the wiring and connected devices from damage that could result from excessive current.
