The Midas draws more current than my others boards. I have 3 power supplies. I also added a few other electrical things at FOH. I need a single cable that will reach up to 150' from front of stage and that means at least 160'. Then it has to connect to the main distro so figure 200'. It is single phase and that means 2 hot legs to a 50A breaker(not a 60A). The Midas is on one phase and everything else is on the other phase. With a 120V at the distro the voltage will be 115V at the Midas on its phase with a 200' cable lenght from the distro with 4/4 cable. With 6/4 the voltage will be 112V. 4/4 cable is the way to go. 6/4 50' cable runs on 45A breakers for the amp racks is plenty. I put my amps behind the speakers and that saves on copper and others things.
Thanks for that explanation. Just out of
curiosity nosiness, how much power does the Midas draw? And do you have all 3 power supplies on at the same time?
Note Tim's response. Relevant to it, by using 240v you also get the benefits of running on balanced power, which many people spend $$$ to get from 120v. Using 240v you get them for free.
Sounds like you have a pretty cool rig.
