The reason for today’s visit was to assess microwave that was tripping the breaker. When we arrived, we attempted turning the microwave on to get the problem to happen again however it never did. We ran the microwave multiple times for minutes at a time and it was running properly. We checked terminations and everything looked good. We even attempted to use a heat gun in the microwave circuit to see if we could simulate the issue and we’re unable to do so. We recommended installation of whole home service protection the main panel as the home does not have any, and we also recommended a replacement of the arc fall breaker as a possible prevention option.

Status LED with an audible alarm. 120kA available in all single and three phase. NEMA 4X (IP65/IP66) indoor/outdoor rated enclosure.
