What condition is referred to as overload in motors?

  1. Voltage is too high

  2. Current exceeds equipment ampacity

  3. Motor speed is too low

  4. Temperature is below normal

The correct answer is: Current exceeds equipment ampacity

The condition referred to as overload in motors occurs when the current flowing through the equipment exceeds its rated ampacity. Ampacity is the maximum amount of electric current a conductor or device can carry before it risks overheating and sustaining damage. When motors experience an overload, they draw more current than what they are designed to handle, which can lead to overheating, reduced efficiency, and ultimately, failure if not addressed. Understanding this concept is critical in electrical applications, as overload conditions can result from factors such as mechanical issues, excessive load demand, or improperly sized motors for specific applications. Recognizing the signs of an overload condition allows electricians to take preventive measures, ensuring safety and longevity of the motor and associated electrical systems.
