Thanks for the info on the drawings and animation. I will save a link for the animation and possibly use it. I suspect that most of this would be too much to expect for them to grasp in only a month of theory. I am thinking I will concentrate on basic electron theory first, so that they understand a bit about conductors, insulators, etc, move to magnetism, basic series and parallel circuits. Basic formulas including ohms law, power, etc. I want them to understand the reasons for wire sizing, OC protection, and understanding of safety issues and precautions that need to be observed and/or initiated. Theory half day, other half practical dealing with overloading of existing feeders, and feeding and wiring of new training shop. I would appreciate advice and am open to suggestions and or constructive criticism about content etc
