OOPS!This is a 3,000 amp service switch. The bolt got a little hot.
I think the others were not torqued well and that one was carrying most of the load.
If you look at all the other bolts, they have a black mark on them. That's what Sparkies
do after we torque one. The three on the blade with the red hot bolt are not marked!
When we finally did a shutdown and replaced it, that bolt just crumbled into dust.
