RV park wiring ?
I always check the park outlet, before plugging in. I recently stayed where my meter was showing 121-122. I know that neutral to ground should be 0. I was getting a reading of 0.6, would this be ca...

Thanks everyone, for the replies! I did not feel that 0.6 between neutral and ground was enough to be a problem. I did plug in, and use the outlet. What concerned me, was that a small amount, could maybe turn into more.
At what amount of current between neutral and ground, would be considered unsafe to plug into?

The NEC specifies (or at least suggests) a maximum voltage drop of 5% in the system; if you assume that is equally spread over the line and the neutral return wiring, it works out to a maximum expected neutral to ground voltage of 3V (for a 120V supply).
Note that you're measuring voltage, not current. Generally speaking, there should be no current at all flowing through the safety ground conductor. (Current flowing through the ground lead means that there's a ground fault of some sort somewhere and indicates some unsafe condition...possibly a very unsafe condition, depending on the nature of the fault.)
