Refrigeration & Air Conditioning Mechanic Red Seal · Question
A refrigeration unit's single-phase compressor motor draws 15.0 A at 240 V and has a power factor of 0.85 lagging when running. What is the approximate true power consumed by the motor?
True power (watts) = Voltage × Amperage × Power Factor (P = V × I × PF). So, P = 240 V × 15.0 A × 0.85 = 3060 W. This represents the actual work done by the mot

Question: A refrigeration unit's single-phase compressor motor draws 15.0 A at 240 V and has a power factor of 0.85 lagging when running. What is the approximate true power consumed by the motor?
Answer options: ✅ 3060 W
- 3600 VA
- 5196 W
- 4248 VA
Correct answer: 3060 W
Explanation: True power (watts) = Voltage × Amperage × Power Factor (P = V × I × PF). So, P = 240 V × 15.0 A × 0.85 = 3060 W. This represents the actual work done by the motor.
