Grounding to bus chassis

[eagle19952]

Bevans6, I get what you are saying and I agree if the genny is sitting outside the bus on the ground.  On the other hand if the genny is a permanent install in the bus then bonding to the genny frame is the ticket.  Jack

airplanes have the same problem.

He did actually refer to Mikes site and followed his instructions to a T. So I guess we are solid.

I didn't read it. I don't really care what OSHA says.   

    Mike Sokol (the "No-Shock" guy) says that ground rods are unreliable.  Despite going to the best ground source there is, there's a fair amount of resistance/impedance in the rod, ground-to-rod interface, wiring, connections, etc.  If there's an electrical defect and the resistance/impedance is lower between an energized coach and the ground through the body of a person touching it, the ground rod does nothing and the person carries all the juice -- with possibly fatal results.  That's pretty simple - a rod may help you but don't depend on it to save your life.

    I'm not an electrical expert but that sounds logical to me.

OSHA is kind of like the bible.  It sets out somewhat reasonable common sense rules that cover a lot of situations, and if you follow them you will probably be OK.  It doesn't cover everything, and sometimes you do something else.
