What to do if the circuit breaker tripped on my MQ Power Portable Generator?
- R
  Randy JensenAug 12, 2025
  If the circuit breaker tripped, it could be due to several reasons. First, check the load for a short circuit and repair it if necessary. Second, the generator might be experiencing overcurrent; confirm the load requirement and reduce it. Third, the circuit breaker itself might be defective, so check and replace it if needed. Finally, the overcurrent relay may have been activated; in this case, confirm the load requirement and replace the relay.

  If there is no voltage output, begin by checking the output voltage using a voltmeter to ensure the AC voltmeter isn't defective. Then, inspect the wiring connections for any looseness and repair them. If those are fine, the AVR might be defective and require replacement. Also, check the rotating rectifier and replace it if needed. Finally, check the exciter field, looking for approximately 19 ohms across terminals J & K on CN1.

  Scott HarveyAug 31, 2025
  If the circuit breaker on your MQ Power Inverter is tripping, it could be due to several reasons. There might be a short circuit in the load, so check the load and repair any issues. It's also possible there's an overcurrent situation; confirm the load requirements and reduce them if necessary. The circuit breaker itself could be defective and need to be checked and replaced. Lastly, the overcurrent relay might have been activated; confirm the load requirement and consider replacing the relay.
