Question

Which of the following overcurrent protection devices would be appropriate for an air-conditioning condensing unit whose rating plate says MAX FUSE or HACR CIRCUIT BREAKER 35 AMPS?

1) FUSE: 40 Amps
2) FUSE: 30 Amps
3) CIRCUIT BREAKER: 30 Amps
4) CIRCUIT BREAKER: 40 Amps

Answer 1

The appropriate overcurrent protection device for the air-conditioning condensing unit would be the circuit breaker with a rating of 30 Amps.

Step-by-step explanation:

In this case, the appropriate overcurrent protection device for the air-conditioning condensing unit would be the CIRCUIT BREAKER: 30 Amps. This is because the rating plate specifies a maximum fuse or circuit breaker value of 35 Amps, and the circuit breaker with a rating of 30 Amps falls within this range.

It is important to choose an overcurrent protection device that is slightly lower than the maximum rating to ensure proper protection. In this case, the circuit breaker with a rating of 30 Amps would provide adequate protection for the air-conditioning condensing unit.
