Must be a bad ground to that unit as well- should have been an elec arc burn/ blown breaker. Last unit that shocked me didn't have a ground all the way back to panel box.

I ran that service call over the winter, so the AC hadn't been turned on between the time the capacitor fell out of the "mount" and the time the customers neighbor noticed the unit running.
The unit has a single pole contactor so the compressor and fan motor common leads have 120v to them all the time.
When the common terminal of the capacitor shorted to the mounting strap, it allowed a 120v current THROUGH the compressor and condenser fan motors to ground, so they both ran at half speed.
Under those conditions the compressor and fan motors will overheat, causing them to cycle on their internal overloads, but the breaker the will not trip because there is no ground fault or over current condition.
The units cabinet and the ground conductor back to the breaker panel essentially become like a neutral wire back to the panel.
The neighbor got shocked because his hands and feet were wet, and he was standing in sloppy mud, so he was a good enough path to ground for some of the current to pass through him.
He almost died because some lazy sack of s
t was to lazy to spend <1 minute to make the capacitor mounting secure.
Exactly what I use!
Loosen one mounting screw a little, pinch the bracket tight and bend it over, then tighten the screw back up.
You could drag the unit around by the capacitor and the folded over metal won't budge.If more government is the answer, then it's a really stupid question.

I was wondering why there was no burn mark on the strap.
I'm not tolerating Political Correctness anymore, from now on it's tell it like it is.

Big money but good stuff.. In another industry, when we wanted for a splice to be protected while the 110yd wire was being dragged through the snow in -45 (that's like -48F) degree weather, that was the stuff we used. I think it cost $6 a roll or something, not sure if it went up or down now.

One way to outthink people is to make them think you think. They'll think you're not really thinking what you're trying to get them to think you think...........
