When a motor is running normally at rated voltage, it is drawing how many amps according to the nameplate?

The correct answer reflects the motor’s rated current as indicated on its nameplate, which represents the amount of current the motor is designed to draw under normal operating conditions at its rated voltage. Each motor is built to operate efficiently and safely at a specific set of parameters, including voltage, current, horsepower, and frequency. The nameplate provides manufacturers' specifications, ensuring that when the motor is supplied with the correct voltage, it operates optimally and securely without drawing excessive current that could lead to overheating or equipment failure.

In this scenario, the number 58.1 amps is presented as the rated current that the motor is expected to draw at nominal operation. This means that under normal load conditions and at the rated voltage, the motor will draw approximately 58.1 amps. Selecting this number as the correct answer signifies understanding how to read and interpret motor nameplates, which is critical for ensuring proper installation and operation in electrical systems.

Knowing the rated current also helps electricians and technicians diagnose issues and assess motor performance. Identifying discrepancies between the actual current drawn and the nameplate value can indicate problems like overloads, motor inefficiencies, or other issues.
