Which electrical checks help prevent compressor overload?

• A. Verify proper electrical supply and overload protection
• B. Increase voltage to the compressor
• C. Remove safety devices or fuses
• D. Disconnect all wiring

Answer: (A)

Preventing compressor overload hinges on giving the motor the right electrical conditions and having solid overload protection in place. When the voltage is within the rated range and the supply is stable, the motor draws the current it needs and the protective device can trip if current spikes beyond safe limits, guarding the windings from overheating. Increasing voltage is not the solution; it can push the motor to draw more current than it can safely handle and stress insulation. Removing safety devices or fuses eliminates protection entirely, raising the risk of overheating and failure. Disconnecting all wiring stops operation but doesn’t provide any protective safeguard. So, checking that the electrical supply matches the motor’s requirements and that proper overload protection is correctly sized and functioning is the best way to prevent overload.
