If you are using a portable generator like Honda or Yamaha you will need to change their floating grounds so that they ground back to themselves. Many portable generators have a ground lug on the control panel that the mfg suggests you wire to a grounding rod---how likely is that going to be? You can find a listing of generators with floating grounds and how to make their grounds go back to the generator rather than a ground rod. With a floating generator ground, it is possible for the "skin" of the bus to become hot (electrified). Under those conditions, should you happen to step out of your bus onto wet ground while you are still, say, hanging onto the step rail, you get to be the ground----a shocking (and potentially deadly) experience.
I was trying to play catch up and read all the post before I commented but TRUNT and I still have not read the no shock zone.
For government construction we are required to use a grounding rod for any portable generator,welding machine and most BS it buy driving a piece of steel whatever in the dirt to look like something and hook jumper cables from rod to equipment frame.
All generators are vibration isolated but have steel bolts through the isolators to the frame but have a ground to frame but as stated it could be unreliable.
For me a ground rod driven into the ground at least 18" and a good sized ground wire connected to the generator ground lug not the frame lug and clamped to the rod is true protection.
With all of that said and everything we do to these busses? Has anyone ever thought about grounding the bus body and a rod on the roof for lightning protection? Because even though the frame is isolated with tires the body is isolated from the frame to an extent?
Laugh if you want to.
Government/base high rise construction they come up with all kinds of electrical safety issues among other things?
I am usually a water man but my company involved me in electrical solar panels on a 5-story metal roof and I had to add seperate lightning protection because lightning looks for a path to ground and all the power from these panels are grounded. And because I was the installer of 70+ panel solar water system I had to install lighting protection on them as well? (Not the owner of the company just the ramrod installer) sucked either way. Water piping does create a path to ground and We did use copper for the glycol/water system so had to ground the piping on the roof and on the first floor at the equipment? Probably over kill but it has put food for thought in my head as far as grounding in/on my all metal structure bus? And what to ground where? Lightning if grounded to the body could blow everything you have including you,unless it is provided a direct path to ground? Ain't scared of it but I swear growing. Up as a kid in texas my DAD was a lightning rod never hit directly but close enough to cause temp. Blindness and 1 time it was because he came to close my bedroom winder after I ignored mom telling me to. I jumped and said ok I got it dad and as soon as he touched the winder the lightning was close enough it temp.blinded both of us? My first but his third?
