[QUOTE="TJ Cornish, post: 137492, member: 162"] Re: Sound & Stage Power IMO, Soca is a poor choice for non-dimmed power distribution. The cable needs to be derated substantially due to a large number of bundled conductors, and there are traps depending on how they're wired - number of grounds, wire gauge, etc. It's also REALLY heavy. As to having all your breakers on a main distro vs branch distribution, I don't know if that's an advantage or not. Many folks like the flexibility of L21-30 or L14-30 at the distro so that can be broken out differently elsewhere in the system depending on need - 208v, 120v, feedthroughs, etc. I don't think you've told us what system you are running - presumably something active? What is the manufacturer's power recommendation? I can't tell if you're hoping for 6 circuits because Soca can do that, or if you really need them. I have a number of 50A 240 volt distros. I'm possibly looking into getting a larger distro at some point, but I have been able to keep my power consumption down due to LED fixtures and efficient audio so it isn't critical. If you always have 3-phase power available, L21-30 is probably the best choice. If you only have split-phase power, L14-30 may be more flexible. Of the two companies I work most closely with, one is a L21-30 shop, the other is an L14-30 shop. [/QUOTE]
