What would cause a QO or HOM arc fault breaker to hum?

Issue:
Humming noise on Homeline/QO arc fault breakers

Product Line:
Miniature Circuit Breakers

Resolution:
The electronics inside the breaker will produce a low humming noise. Solid state dimmers will make them buzz louder, but this is normal and is no cause for concern.
