After starting a generator, what is a key operating check before applying load?

• A. Monitor voltage and wave quality, then connect to load gradually.
• B. Immediately connect to full load to test capacity.
• C. Shut it down to verify start reliability.
• D. Increase load without monitoring.

Answer: (A)

After starting, the key check is that the electrical output is stable and within spec before loading it. Verify the voltage is at the rated level, the frequency is correct, and the waveform is clean with minimal distortion. If these parameters look good, bring the load on gradually so the automatic voltage regulator and governor can respond and the generator can settle. This prevents voltage dips, waveform distortion, or overloading that can damage equipment or the generator. If the output isn’t within spec, address the regulation or mechanical issues first before adding load.
