Re: Is this enough juice to kill ya?
Was your skin wet? If your skin was dry like it is here in the winter, you might have to put pressure on the terminals to feel the buzz.
Wait until you work with 480 volts. The voltage is high enough to boil tissues (make your fingertips pop off!) Each phase to ground is only 277 volts. Never known anyone that got hurt from it.
I worked with a few people who tried to test the primary side of the substations with their $450 NIST calibrated Fluke multimeter. 14,400 volts turned it into an instant burned piece of toast. Fluke honored their warranty and gave us a new one both times no questions asked! When you open up a large door with a big arm and see fuses with mufflers on them, you know there's serious high voltage in there. The mufflers on high voltage fuses keep the switchgear panels from blowing off when they blow.
I currently work with someone who dropped a wrench in a 2000KVA substation. All the energy went into vaporizing a tiny speck of the wrench into a huge metal plasma fireball of ultraviolet light and heat. He didn't get shocked, but looked like he had major sunburn over most of his body. He came back to work in the hospital gown since his clothes were blown off in the accident. One of the guys at work happens to be a professional photographer. I still have that picture somewhere...
I can tell you what its like to get hit by a 8uF capacitor at 15,000 volts from a cable tester. I heard a loud bang and lost my vision for a few minutes. I was still standing, but I would soon notice my arms were sore as hell. This cable tester would blow holes in cable or cause fluoresent lights to explode into dust, yet didn't burn me for some reason. I measured 8,000 volts left on the capacitor.
