. . .
So I'm all over the place with this. I feel like two poles of 50 amps using 6/4 SOOW should be enough which would give me a 30 amp for the Powerlight, three 20 amps, one for each amp rack, and a 15 amp for the remainder processing equipment. But are separate 20 amp circuits really enough to drive the amp racks (subs excluded)
Unfortunately SOOW cable is stupidly expensive so I would really like to get this right the first time.
Everyone (mostly) I know that does this ends up breaking out CS50 or cam lock to L14-30 to run to amp and drive racks. Only one type of cable to manage that way and it gets both phases into every rack. 30A cable is more common than 20A cable.
I know some big time lighting companies that break out to L21-30 but that precludes their distress running single phase.
