Low current event

Anonymous user · ‎2021-06-29

Some background: We recently had a HVAC failure that tripped the breaker assigned to that system. In so doing, it also caused a low current event across other circuits in my home and caused failure of circuit boards on two appliances. Though I'm not an electrician, I have self-diagnosed this as a "low current event" as the event-log on my PC (using apcupsd software) registered a one-second "power failure" each time we tried to reset the HVAC breaker...even though the power didn't go off.

Fortunately the APC UPS protected my computer equipment, however I was surprised to have this low current event as I had a SurgeArrest Panelmount Surge Suppressor PMP1X-A installed ~18 mos ago. According to the documentation on the PMP1X-A, this device should "react quickly to protect against dangerous high and low current wiring faults as well as other catastrophic surge events." Can anyone help me understand if I am interpreting the PMP1X-A documentation correctly? Is there something else I'm missing here?

Thank you!
