One of the things that applies here. Though yes, a VOLT METER which is a "High Impeadance" device will show 60 volts between neutral and ground if not bonded.
You may fear this as unsafe.. But voltage does not kill.. I have proven in fact that voltage does not kill as I've been right close to 1,000,000 volts and I'm still here typing.. I have a funny story about it if you like (Perfedtly safe by the way and I knew that.. in fact only two people in the room knew that,< The Professor and myself, before the demo,, So I was the volunteer from the audience).
What kills is CURRENT and it takes a lot less than 60 volts to shove fatal current through a human heart
BUT... How much current can you draw on that Neutral/Ground pair before the voltage drops to a safe level.. Well, enough to get a tingle, but not nearly enough to be dangerous.
Here is why
The voltage is present due to the nature of conductors, seperated by insulation
Two conductive plates OR WIRES, seperated by a dielectric (Insulation)(form a capacitor.. The wires are layed out like this
HOT-----
Ground--
Neutral-
So as you can see, the ground wire is "Sandwitched" between the hot and the Neutral Thus it is forming two capacitors.. Kind of like this electronically..
---||-t-||----
The "T" is the safeth ground Hot and Neutral are on the ends.
-||- Is the electronic symbol for a non-polorized capacitor
Though the voltage is halved on the center wire,, The capatiance is low so the impedance is fairly high, start drawing current and it's like a really big resistor in the line.. Voltage goes POOF for all practical purposes. So instead of the shock of your life you get a tingle..
I accidently tested that theory.. Though the inverter out IS bonded on this RV,, The Generator.. Is not.
