Highest shock voltage

[B4T]

Lets keep in mind 240 to ground is usually 120, 480 to ground 277 etc. :smile:

It was a Delta service that got me with 240. The FPE was off, but the breaker was still live

480 VAC once and it seemed like minutes as I shouted JO JO JO JO JO JO JO JOEL then he hit me and I hit the ground.

10KV from a megger once from a mechanic not following rules.

120 first as a child stuck my finger between the blades of a lamp plug 1/2inserted in outlet. 120 hundreds of times as a service electrician and still counting. 277 about a dozen times hung up really bad once I disconnected when my knees buckled on a lift 30' in the air. I am still not right from that one. 2nd Worst was friend kicked over dirt bike magneto while I was holding plug out of motor. #1 altime worst was off an open circuit high energy ignition of a pontiac fierro 60-80k dc right through my 5kv kleins like they werent even insulated REALLY REALLY PAINFULL!! I will not work HIE systems hot any more. I probably pulled the voltage down when I connected but holy macaroli did I get whacked.

It's like the way people say that two cars going 60mph hitting head on is like one car hitting a wall at 120mph.

So it's not the same as 1 car at 120 mph?

Does it count if I can tell you the voltage and size of cartridge fuse (phase to phase -or- phase to ground )by the listening to the intensity of the Kaboom. Knowlege was gained while working machine maintenance at a rubber press shop. Rewired a bunch of WWII era rod heaters: It was cheaper than replacing fuses.

277 once from a backfed set of fuses. 10,000 once from a burner ignition transformer. Worst ever was at my dad's new (to him) house. Had a metal medicine chest with vanity light. I remembered afterward him telling me he would get a buzz from it once in awhile. Anyway, I get out of the shower, bend over to dry off with my foot on the tub and my wet hair touched the med chest. I have to imagine that's what a baseball feels like after getting hit by Barry Bonds. Dad got a new medicine chest later that day.

I think it was 400VDC while working on a Gibson Girl. The guy standing next to me said that I tried to grab his arm. I had a Navy issue pocket knilfe in my hand with the screwdriver blade opened which I threw in the air and took some time to find! My back and neck were sore for days.

You know what I mean, most times people say something like'I got hit with 50 amps 240' but when you ask about it it was to ground.

Few of us are dumb enough to go line to line. :wink:

a-b-c evenly spaced on right forearm. 480. a near wrist, c near elbow.
blew me back out of the transformer straight legged on the floor.

trade show, anaheim convention center. "b" hall. machine tool show. 1982.
end of a 14 hour day, and i was too tired to walk up to the catwalk and
lock it off. it was dead on the primaries, and i went in to fish the secondary
cam lock tail in thru a chase nipple in the bottom of the xfmr. someone turned
it on at that instant up in the catwalks. there were only two of us working
at that point in b hall, and he swears he didn't do it.

i tasted copper for about 3 days afterwards. pure pilot error on my part.
really flipping dumb.

the first miracle was there was no burn or damage.
the second miracle was i couldn't find the guy when i went up on the
catwalk looking for him with a chain wrench.

everybody was lucky that day.

Nope. The approach speed with two cars might be double, but the impact to each car is the same as hitting a wall. The energy of the second car is expended countering the energy of the first car.

Picture each scenario.

If both cars have the same mass and are traveling the same speed, the point of impact over the earth doesn't move, just as it wouldn't with one car hitting an immovable wall.

Likewise, a car traveling at 60mph hitting a stationary equal-weight car (in neutral, no brake) will have the same impact as two cars, each traveling at 30mph, hitting head-on.

Pardonnez moi?

I forgot about getting bit by a lawn mower spark plug once and another time i got it from a flame rod (several thousand vts.micro amps) on an industrial oven. While neither was probably dangerous they both caused some very bad language.

Trouble shooting old M-G set battery charger. Needed to make adjustments in the control panel, partner 25' away would turn power off and back on, I'd adjust a little bit, about the 5th time he complained about having to walk back and forth. Next time I decided to just make the last little tweak without him shutting the power off, I couldn't stand to listen to him whine when I was doing the work!
I am hot, soaking wet, my rubber boots are squishing with sweat, I was sitting on one cheek on a wet wooden platform, my feet are pushed against a metal rail to hold me in place, and my shoulder is leaning on the charger cabinet. I reach up inside, and I THINK my little finger made contact with 480 vac. I honestly saw sparks coming off my RUBBER boots at the metal rail, my left bicep felt like someone clobbered me with a baseball bat. That arm was sore for three days. I threatened him with death if I ever heard that B.S. out of him again!

Huh? F=M*A, you cant change physics

 

[electricguy61]

60mph head on = seriously injured/sometimes dead
75+mph head on = seriously injured/usually dead

I've cut a few folks out of cars in my younger years as a firefighter, many were bodies, unless they were really drunk, then only the folks they hit were hurt or dead (sometimes life's not fair)

Hmmm....does a Tazer count? Don't know how many volts that was.

Got hit with 277 one time my first year doing commercial work. Tip of my finger was just barely grazing my Kleins, while my elbow was resting on some conduit. Had to sit down for awhile after that one.

I laid awake all night that night thinking to myself...do I really want to be an electrician anymore? Apparently the jolt was not hard enough though.:grin:

 

[Minuteman]

Back to the OP. I answered 277 volts, but I got to thinking.

What is the secondary voltage on the old F96/T12 ballasts? I touched that once and it curled the hair on my toes.

 

[rbalex]

Although it was fairly brief, I permitted a charged capacitor (~620 - 740V) to discharge between my wrist and elbow. No excuse, it was a college lab experiment and the instuctor gave perfectly clear safety instuctions - no one else was nailed.

 

[LarryFine]

To which premise is that aimed?

Umm, Larry. This statement just contradicts the one you made earlier that I questioned. I agree and have always believed that 2 cars head on at 30 mph each is the same as 1 car 60 mph hitting the other car sitting motionless.

So my point is that your previous post doesn't make much sense. Unless I'm missing your point.
