If an electrical pump is installed on an A/C system, what type of rating is required?

In an air conditioning system where an electrical pump is installed, the required rating is continuous. This is because the pump is typically expected to run for prolonged periods without overheating or suffering from excessive wear. Continuous duty means that the pump can operate at its rated load for an indefinite period, which is crucial for maintaining proper functionality and efficiency in HVAC systems.

Using a continuous rating ensures that the pump can handle the demands of the A/C system without tripping the circuit or failing prematurely. This is particularly important in HVAC applications, where consistent operation is needed to maintain desired temperature and humidity levels effectively.

The other ratings, such as intermittent, imply that the equipment is only used for short durations and might not be suitable for the continuous operation needed in air conditioning applications. Therefore, a continuous rating is essential to ensure the reliable performance and longevity of the pump in an A/C system.
