Well they did it to me...

I found out today... with 9 days and counting to finish... that the show lighting will require 240V 200A... not sure how they will be split up... 10 20A 240V circuits?... Don't know yet.... [Linked Image]

The service I'm working on tomorrow for it only has a 25KVa Xformer. There is a 50KVa about 500 feet away...

It is going to be a miracle if I pull this off.

The sound wants 6 20A circuits that does not share the pole(s) with any other non-sound circuit. So figure 100A at 120V for them (80% of 20A x 6= 96A)

This doesn't include any ambient/security/convenience lighting or any of the concessions.

The show has been moved to a new location since the last time I mentioned the festival...

My questions are many...

Is SOW cable my only option? ($$$$$$$$$)
Can I run Schedule 80 PVC on the surface of the ground? (with THWN) How do I secure it?
What other options do I have for exposed wet location cable? UF? (Subject to probable physical damage)

This will be a Temporary Wiring situation, under NEC Chapters 305 and 525.

I have 9 days.... It wasn't my fault...
But this whole $50,000 investment is riding on my shoulders to produce a miracle. And they're giving me a whopping $700 to start with tomorrow.

(Plus I'm roughing in a house for a GC I want to impress!)

How much headroom do I have with a 25KVa Xformer? 108A @ 240V?

Boy... if the lighting was 120V for 200A I'd be set...

Gaffer's nightmare? (Did I get the name right this time?)

Plus my band plays a 1-1/2 hour set on Friday night there...
