Made me hmmmmmmmmmmmmmmmm too.



Was that a factory installed breaker you took out?

Look close.

Did it have a loose screw?
Or a screw loose?

Bottom phase had no screw installed. Minor detail but no threads either. Factory install. Look close at the top finger & it looks like a pretty rough thread. Like maybe it was over torqed or cross threaded. Center is what they are all supposed to look like, nice factory thread. My help said the others he had out looked, like the top hole. Someone with an impact and not a care in the world.

I have had the same trouble with Siemens MCC's here lately. Their QC is leaving a lot to be desired.
