ABSTRACT
Once a lighting and electrical system is properly laid out the next task is to communicate all of the associated information to everyone who needs to access it, especially those who will assist in prepping the gear for the show, loading it in, and setting it up. When current flows through a conductor it produces heat, and if enough heat is generated then it will begin to deteriorate the insulation around that conductor, damaging it and possibly other components such as connectors and terminations. So the amount of current that an electrical power distribution system can handle before it starts to deteriorate or damage components due to heating is the main limiting factor of the system. We have to plan carefully to avoid overloading circuits, and that takes a good understanding of how to design and build lighting and electrical systems. The specifications provided by the manufacturers of lighting instruments and the lighting plot are good places to start planning.
