QUESTION 7 OF 35

What does a fuse or circuit breaker do? What are the differences between the two?

"Both fuses and breakers are protective devices. Fuses are quicker to interrupt power flow but are one-time use and need replacement. Circuit breakers simply need a reset."

The interviewer wants to know that you can confidently relay the differences between standard electrical equipment and solutions. Your response should be factual and to the point. Be sure to memorize your answer so that you are clear and do not stumble through it.

"The fuse works on the electrical and thermal properties of the conducting material, while a circuit breaker works on the electromechanical principles."
