HI , Sean here

I'm an electrical technology student at HACC Harrisburg Area Community College in Pennsylvania( first semester ) with a test question I'm not sure of .............. what is safe(ty) voltage ?

Thanks , Sean

Sorry, but that phrase does not mean anything to me. Can you give us the context in which you encountered it (i.e., the entire wording of the test question)?

Welcome to the forum.

Hi Charlie ,

Sorry to be so vague . That was the question in it's entirety .

Turns out the professor was leaving that open ended . He was just trying to get us to think and said the definition is whatever we interpret it to be . My answer : It's an oxymoron.

Thanks for the welcome ,

Sean

OSHA and the NFPA 70E require the use of safe work practices (Shock protection, EEWP's, etc/) on system that are >50V.

..... My answer : It's an oxymoron......

My answer then: Zero volts.

4000A @ 24V is "safe" then?

Volts hurt, amps kill, but the higher the voltage, the more amps your body will conduct.

Talking about electric shock? Yes, dosent matter how much load is on the system, the current through your body is the voltage drop across your body divided by the resistance of the tiisue between those 2 points.

1A of load or 4000A of load, same shock.
