Let me preface this by saying this breaker was purchased off of Ebay from PLC center used. After doing all the wiring yesterday, the breaker would not reset so that the visitrip indicator (red flag in window) would always show a blown breaker condition. With the breaker out of the panel it resets just fine. All the wiring is 6 guage thnn running through 1" conduit. The coiled white from the breaker goes to the neutral buss bar and the white load hooks into the bottom right of the breaker itself. I tested the wiring and did not find any leaks. I even unhooked both hots to the breaker, so the only thing hooked to the breaker was the load neutral, and the breakers coiled neutral to the neutral buss bar. The breaker would still not reset. I am snapping the breaker into the panel with it in the off position, then trying to turn it to the on poition, only get a red flag. I assume that the breaker is bad.
