Ok, as a retired lighting designer, master electrician and working sound
designer, this is a no-brainer. No matter what the NEC says, it doesn't make
any "common sense". It's in the same category as those mis-guided folks that
put Edison connectors on speaker lines for "convenience". I wouldn't let this
guy near my venue.

response might be too late for this situation, but I don't think anyone has
quoted chapter & verse, so I'll add my two cents for future reference:


As others have pointed out, NEC Art 520-68 requires 'extra hard service' cables
for portable power distribution in entertainment venues.

Additionally:
--Art 210-7(f) says that you can't use connectors of a given type for more than
one voltage, frequency, or type of current (AC or DC) within the same premise.
