I have a 2 pole 40 amp shunt breaker that trips everytime the power goes off in the building. Is this normal or what can I do to rectify this problem?:001_huh:
Check for under voltage release in lieu if shunt trip.
Shunt trip you power to open.
Under voltage remains powered to keep CB closed.
Check for controls such as a UV relay or relay that operates and trips the CB on loss or restoration of power.[All I did was install the breaker. TheAnsul installers wired everything within the unit, do you think I should have them come out and check (controls such as a UV relay or relay that operates and trips the CB on loss or restoration of power)?]
I have never had an Ansul installer wire the shunt trips nor have I ever seen them do it. Around here, that is not their work nor are they licensed to do it. It has always been my job.
The older systems, Do you think those enclosures were rated? Those open splices and cheapo micro sws.:laughing:
