I am currently searching for a good power distribution howto on the web. I need some good information on how to properly tie in power to dimmer racks(methods, etc.). We generally tie in a lot of power to run shows, and need a good way to explain what we are doing so our new guys don't screw something up. We generally only have a supervisor do the actual tie in, but in an effort to train we need to find some good info. If anyone knows of where I could go to get this info, please let me know.
