Almost died unhooking amp the other day

Sh it is getting real.

co-worker installing new batteries in the dually got overconfident and dropped one of them in the tray facing opposite polarity and plugged one wire and when he dropped the terminal in the other the ***** exploded, not the battery, but both the clamp on the wire and the post were gone. pulled his hand away n it was red all nasty n horrible, shaking the **** outta his hand. burns were pretty bad.

12 volt does not kill bro

12V can easily kill, just get some of the current to pass across something vital.

But yeah, barely any conductivity in the body for such low potential, no where near being killed from your vehicle.

Next time try a full bathtub and a plugged in appliance

Full tube would do the same as a tube w/1". Electricity flows on the surface.

Then how are you here?

The amperage wasn't high enough. Just because it's 440/480 doesn't mean if you touch it, it will kill you.

The most correct answer is that the combination of voltage and amperage is what is dangerous. Voltage is, basically speaking, the 'pushing force' behind the current flow, while amperage is the amount of current flowing.

A car battery can deliver hundreds of amps, but touching both terminals at the same time is unlikely to cause current to pass through your body because the voltage (pushing force) is too low to overcome the resistance your body presents to the would-be circuit.

But yes, a high voltage but low current circuit isn't necessarily dangerous either. The potential to have the current pass through your body is greater, since the voltage (pushing force) is high, but even if it does pass through, the amperage is small enough to avoid much/any permanent harm.

Usually when someone talks about getting hit by 240 or 480, they are talking about a house or building circuit, where the breaker could be as much as 30 amps (or more in the case of an industrial setting). 30 amps at 480 volts is wicked dangerous.

Its also worth noting that how well you/your body is grounded also affects the potential for harm. This is why standing in water when handling an electrical circuit is much more dangerous than a dry situation.

I was going to say that, but was to tired to go on. I'm on muscle relaxers and it doesn't play well with me.

I didn't take a picture of it happening lol. Anyways my car was on and If my other arm was touching metal it would have completed a circuit //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

Umm, did you do any circuitry work when you were in school? Cause in order for a circuit to be complete, there must be power... If you touched the ground wire and the chassis, there would be NO power flowing through... You would essentially be touching the chassis in two places, one just connected by a wire...

D/C 12v you would have completed a circuit that won't make your heart stop beating. Would hurt though.

Considering .01a is all that's necessary to stop a heart, 30A breaker on 480v is more often than not fatal.

hold a metal wrench in your hand....stick it across the terminals on a 12v automotive battery and see what happens. That will tell you real fast if the 12 volts will fry you.

No one will believe me, but water is a POOR conductor. //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

Depends on your water... If it is distilled, it is actually a great insulator... that is the reason that they use it in nuclear reactors and what not. However, if it has foreign particles in it, water is a decent conductor. //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif//content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

Fawking woot, im surprised anyone on here other than me knew that lol.

Pure H2O is a ****** conductor, but if you add salt or any other ionic compound to it, that separates. it becomes pretty conductive

When this happens to you come back and tell us you almost died.
