4,160 Chuck.
On base at the airfield lighting vault we had some odd ball 4,600 the low stuff can carry a lot of amps! In the early mornings working on the lines the moist air would cause excessive crona snapping and popping on my rubber sleeves I could fill it in my arms.
Near the end of my career I had complete rubber glove failure one warm sunny day while up in the fiberglass bucket the shock went through my arms and chest shook my like arm back and forth and tossed me down into the bottom of the bucket.
I finished up college degree fast as possible and in a 1yr ish time I started my new career at a engineering firm whewww
