Buzzing Breakers on Sensor IQ

Symptoms/Issue

Sensor IQ Breakers are buzzing when connected to certain third party loads (especially large number of small switch mode power supplies (e.g. LED drivers) without power factor correction). In this case, when swapping load wires between breakers, the buzzing issue follows the load and does not stay with the breaker. This does not effect performance, nor is it a safety issue. If you are experiencing this issue and would like to discuss this issue in more depth, please contact ETC Technical Support.
