Want to see a UL approved electrical device that failed on me big-time? (I carry a melted one in my work truck to show other electricians who use them)
Although rated for 240v, I will only use these on low-voltage circuits now. |
It's not the voltage, but the current that would cause this to fail. Voltage rating pertains to the insulation. I would bet it was improperly used.
I have seen many screws loosen over the years also. Open any panel 5 years later, and the screws can be tightened on the breakers. I trust the push-ins.
