I'm surprised that the lack of bonding was overlooked- that is the main thing my inspectors look at-too many drivers in a box is something from an install manual that may or may not be available to the inspectors.

The reason I argued that lack of bonding is the primary cause is because even if rest of the install was perfect-the possibility still exists for a driver to fail energizing the rail.  Circuit breakers and fuses provide a great deal of protection-but proper bonding is a must for them to do their job.

Nothing to argue over ( obviously this is arm chair quarter backing) I simply wanted to make the point that bonding of metal handrails/ staging is critically important whether at the MGM or your next gig.
