Hi All, l have been pondering this in my head for absolutely ages and need an answer, if possible, to help me grasp this subject.

I understand that a person receives an electric shock when touching both a live conductor 230V, and an earth/neutral conductor 0V at the same time, because the live conductor is chasing 0V to continue the electrical path.

Now as far as im aware, a high enough current 80-100mA would cause a person's nerves to contract, with them not being able to let go.

Now if a person was to touch a live conductor, with no earth/neutral return path, would that person recieve an electrical shock? The person touches the live conductor of 230V, yet has themself a potential of 0V, so in theory, some electric current should be able to pass between these two points.

WOULD THIS CAUSE THE PERSON TO RECEIVE AN ELECTRIC SHOCK, AND 'THROW THEM OFF' AS THERE IS NO EARTH/NEUTRAL RETURN PATH?

ALSO WITH THE SAME PRINCIPLE, WHY DOES ELECTRIC SEPARATION PROTECT A PERSON WHEN THE LIVE CONDUCTOR IS 230V, YET THE PERSON IS 0V?

All feedback welcome ppl.. .:cool:
 
Wouldn't fancy trying that one out on a 45 amp 3036
No, me neither. Presumably in an 'extra conductive location' you would need a faster operating protective device, and probably a lower voltage.
I'm not sure what the point of an 'extra conductive location' would be apart from to demonstrate a point, which is probably why they're so rare.

Only the N side of the lamp would be at 0v if you went further along the element the voltage would rise.

The electrical screw drivers testers should be outlawed. I agree with all the replies and throw your tester in the trash, they are dangerous.
