Is a neutral ground bond plug safe
This is just a curiosity question, I'm not getting shocked and I'm not planning on building a neutral ground plug. I read on here about hot skin issues where a person is getting shocked by their RV...
Forum Discussion
Hot Skin requires that the generator be earth grounded.
Normal wiring in an 30 amp RV the SKIN wants to be at 60 volts.. You can't draw much current but ti wants to be at 60 volts.. I can explain the reason but unless you have a background in electronics I'm not sure how well you will understand.
On a 50 amp RV plugged into 120 volts it's even higher Like 80. still low current though.
The bonding plug takes it to zero relative to neutral So it's safe Some devices need it. Some do not.
The reason
A device called a voltager divider..
Imagine the following DC circuit (I do not need I actually used it)
Battery 12 volt----Light bulb---X----Identical Light Bulb--- Ground
Now the voltage at X.. six volts Makes sense right (This is the SEE ME Day time Running Light system by the way, how it works. . Told you I used one)
Now.. for an AC circuit.
A capacitor is two pieces of conductive metal with an insulator (Even air) between them The symbol is --)|---
Now think about a length of ROMEX cable
There is a black wire next to a bare wire ( ---)|--- )
And there is a white wire on the other side of the bare wire ( ---)|--- )
Result is ---)|----G---|(---
60 volts at G.. Just like the 6 volts in the DC example
But very low current as they are very small Capicators.
