What chapter of the IPEC (Inter-Planetary Electric Code) applies to Jupiter? (Sorry -- couldn't resist)
An interesting venue. I can see several elements that require intelligent discussion between the AHJ, the designers, and the tradesmen. This is no job for cookie-cutter code application or hiding behind NRTL labels!
For example, I doubt that menorah, or its' controls, is listed by anyone. The applicable standards are pretty straightforward, but it takes a certain amount of discernment to know where to "bend" and how to address the basic concerns.
Likewise . . . how does one change some of those light bulbs?
Need I mention the problems when broken glass and pools meet?
Whether it be pool lights or stairway lights, I've had very little luck working with the equipment. It's nearly impossible to replace wires without bringing in a bulldozer. Maybe I've just seen poorly designed jobs.
GFI's? I'm sure that stage was -- at some time -- grounded and protected like nothing you've ever seen. Yet . . . apart from the usual corrosion concerns, you can be sure the grounding was modified over time as sound technicians tries to eliminate interference.
Even a properly working GFI won't detect faults that also tie into the neutral. The person is simply another load. You can't count on there being a poor return path when the masonry is wet and bare skin is in contact.
