HOLT Electricians Practice Exam

What is the minimum rating that the nameplate on a generator must indicate?

1. Power factor

2. Voltage

3. Frequency

4. All of the above

The correct answer is: All of the above

The minimum rating that the nameplate on a generator must indicate includes power factor, voltage, and frequency, which collectively provides essential information about the performance and compatibility of the generator within an electrical system. Power factor reflects the efficiency with which the generator can convert electrical power into useful work output, indicating how effectively the generated power is being utilized. Voltage is crucial as it shows the potential difference that the generator can deliver, which ensures that it can correctly match the needs of the connected equipment. Frequency indicates the rate at which alternating current cycles change direction, which is vital for the synchronized operation of devices powered by the generator. By including all of these ratings on the nameplate, it allows users and electricians to assess the generator's capability and ensure proper setup for efficient and safe operation within various electrical applications.
