I've been reading and trying to understand ungrounded systems, pros and cons, and some history on the grounded system we use in this country and got to the part about undgrounded systems in dairy farms and hospital operating rooms. So i go to work and there in the hospital I been helping remodel for the last 3 months is working isolation system that i can stick my meter in and try to learn something.
So on the regular hospital grade duplex recepticle I get 120 volts between the hot and the normally neutral side, I get 60 volts from the hot side to the ground pin, and 60 from the normally neutral side to the ground pin, also 60 volts each side to the chassis. I'm understanding that the ground is not tied to the neutral and is an earth ground, but what I'm not understanding is how this system prevents electrical shocks, (60 volts), in a wet procedure location? Thanks for all the help..
