What protects the electrical system from overloads and can usually be reactivated by resetting them?
Circuit breakers
Fuses
Connectors
Switches
The correct answer is: Circuit breakers
The correct answer is circuit breakers, as they are specifically designed to protect an electrical system from overloads and short circuits. When an overload occurs, a circuit breaker will automatically disconnect the electrical flow to prevent damage to the wiring and electrical devices. After the issue is resolved, circuit breakers can be easily reset to restore power without requiring replacement, making them a convenient and reusable choice for overcurrent protection. In contrast, fuses also serve a similar purpose of protecting against overloads, but they must be replaced once they blow. Connectors do not provide overload protection; instead, they are used to make connections between wires and components in an electrical circuit. Switches are used to control the flow of electricity in a circuit but do not protect against overloads. Thus, circuit breakers stand out as the correct choice for reactivation after an overload incident.
