Front

Safety devices that prevent the overheating of electric wires are known as: fuses and circuit breakers, fuses and busters, circuit breakers and volts, fuses and conductors

Back

fuses and circuit breakers

Answer explanation

In an electrical system, fuses and circuit breakers play crucial roles in preventing overheating and potential fire hazards. They are designed to interrupt the flow of electricity if an overload or short-circuit condition occurs. This helps to protect the wiring and devices from damage. Hence, the correct answer to the question is 'fuses and circuit breakers'. Other options do not fulfill the safety function in preventing the overheating of electric wires.
