Describe circuit breakers.
What will be an ideal response?
Circuit breakers are electromechanical units that automatically disconnect a circuit when the current attains an established value that would cause overheating or a possible fire in the circuit. Examples of occurrences that could cause a circuit breaker to open are excess current flow caused by overloading or a short in the circuit. Circuit breakers are available in a molded case inserted in the circuit at the panel or a large air-type breaker not in a protective case. When a circuit breaker opens a circuit, the breaker is reset by moving the switch handle after the deficiency has been corrected.
