Are you confident in that? ?
I am not confident in that. ?
You are correct. It depends on so many factors from moisture to skin salts to resistance across the unintended path.
Why?
The answer always depends....
That’s high voltage and maybe not felt. Van De Graf Effect
talking offgrid dc. My ground is actual earth ground and bonded to negative. Positive battery reaches 56volt and positive solar reaches 140v. If i want to play around with my 5 strings on panels i could parallel them to keep up close to 700volt at 10 amp load.
I try ask again, in normal use case, how much voltage is needed to push though my body and a shit ton of building material between my feet and ground/negative/earth
Use case denotes study parameters but I digress.
In your
example criteria it STILL depends.
56VDC will almost definitely zap you and is above the threshold for injury or risk of heart failure depending on path and continuity value. 120VDC is a lethal range not worth playing risk analysis with: don’t do it.
salinity level of that moisture
Fortunately uric acid salt isn’t the
best conductor but does it matter?
if you cut yourself accidentally and then touch 12V with in the cut (with a bloody surface) it gives you a pretty nasty - unexpected- shock
i learned that my fluxcore 120V portable Lincoln welder can zap you through sweaty gloves and up your knee while welding metal outside on grass. Probably 35-40VDC.
I’ve also learned that a 12v starter battery in a bonded aluminum boat can give you a burning sensation on a a hot sweaty day. 12V! No blood! Takes a minute but you figure it out.
A 20V lithium cordless drill battery made me think I got a metal splinter for a moment once. Can’t remember the exact circumstances but I remember the pain in my thumb.
Then there is the
TENS therapy devices - lotsa volts but no damage to humans.
So the answer is IT DEPENDS. (sorry)
Avoid anything that can shock you. RUN away from anything 55VDC+ (osha says 50V)
