I imagine the big tours employ their own electricians who handle bonding, rather than depending on the stagehands and engineers to do that when they're plugging in mics and amps.

It appeared on the Stones stage and set I was working on that the bonding was engineered into the build process - IIRC the bonding points were welded to the steel and there were multiple jumpers between primary structure and stage subassemblies.  Whether or not StageCo used electricians or their stage techs, I don't know.  I'm fairly certain that local hands did not perform this task.

And this is done in practice?  Obviously supposed to.  Do most large productions adhere to this strictly, or loosely?

As one of the production managers I know well has said to folks providing temporary stages/power...

Are you going to bond the stage to the genny grounding stake?

No..we never do.

Ok, can I get a business card?

Sure, why?

I need to make sure we get your name spelt correctly for the lawyers.

I'll go get some wire and clamps.

 Years ago I did a small outdoor gig where they had loud gasoline generators. One wasn’t enough to run the whole show, so I used one for backline and one for sound system.   I made sure that they were separate and none of one “touched” the other. I did this by putting a Mac on the bass can (no di), and running acoustic guitar pedals off power allocated to sound system.  Show went fine.

 Since then he crosses my mind if that was even a proper thing to do.  Would it have been fine for them to share a grounding rod? Did I do it the smart way by keeping them isolated from each other?

I always thought the danger here was holding onto a guitar and lips touching a microphone. Wouldn’t that be no longer isolated?

For the OP

To be clear, when using generators, one should BOND the neutral to ground. Also, one should BOND metallic structures to ground. Also, the ground should be BONDED to Earth.

There should only be ONE ground. All ground leads should connect together.
