The knowledge base of this forum’s membership is staggering. Way too much for my last two rubbing brain cells to fully comprehend. 😝 Still addictively interesting.
It was a four sided crimp with a 10 AWG ferrule. I spotted the heat by chance with thermal imaging as I swung the camera past. The torque was set by years of experience, common sense and not wanting to break or tweak the dang thing. It wasn’t a case of less is more.
I have this style breaker and it is designed for stranded wires. The serrated surface isn’t raised so it does little to help retain the wire. After tightening 10 AWG thhn, I found that I could wiggle the wire out after using reasonable amount of tightening torque without distorting the case...
Looks like the main event will hit the west coast about 6 pm Saturday if I figured the 1 am Sunday UTC time difference correctly. I don’t think we’ll see a light show in daylight.
Yeah, I think I’m opening the breaker to the grid before I go to work in the morning. Probably the best thing to do. I’ve got one big house surge arrestor for what ever that’s worth.
When you lubricate the threads you increase the tension in the threads of the older terminals. The welded stud type is actually a captivated stud within a welded on aluminum puck. I’ve heard of both types pulling out when exceeding the torque specs for that cell model.
I know that smoldering and a burning fire emit different substances into the air, having a combination ion and photoelectric will give you the very earliest warning possible . Add a carbon monoxide detector for hydrogen detection you would have the ultimate system. I have a heat detector but by...
