As the EC, I would do 2 circuits, 20 amp @ 240 volt. I did a lot of lighting as an EC back in the day, both interior and site lighting. A lot of design/ build, retrofit HPS to MH (no LED back then) . We even eliminated LPS site lighting.
Yoop has 9 fixtures, probably 3 rows of 3 ea., so a 5/4 split would not be bad, one row of 3 with the center of the next row, then the balance of 5.
I wonder IF he considered LED, or T-5 high bays??
There's a lot of LED retro going on here, and I'm amazed at the rapidly changing technology. I just started plan review today on some crazy 'arcade' in a mall, and it is 99% LED. A recent Apple retail store is 100% LED, with a gorgeous evenly lit ceiling in the whole retail area.
If John is right about the total load (ballast plus lights = 4600w) your original plan may be the way to go (25a/ 10ga wire). If you find out it is really only 400w per luminaire, you can do 20a / 12ga.
I see that. It appears that all of those lights carry an overhead beyond the nominal watt rating of the light. My only question is whether the "max amps" is the initial starting current or the continuous load once they start and settle down. That would make a difference when you were calculating the continuous load.
