Looking for some websites or books that will help me learn how to do this. Or if anyone can help, visuals are needed!

I want to learn how to build a distro box for audio. Input will be 3 phase camloc, output will be several circuts of 120v edison. I know the concepts of 3 phase power and transformer architecture (wye/ delta) But I haven't found a resourse that puts all these concepts into a concise explaination of how I can make them work together. I'm looking for a wiring diagram including the necissary circut breakers on primary and secondary sides. Do I even need a transformer? I have no idea. I'm an audio guy. Help me out here.

It's going to be a portable unit in your standard small panelbox size, about 12"x18"
