I am a power engineer at a utility company, I would like to begin doing residential/commercial design work in my spare time. I understand the math and materials, but I have never worked with design documents. Does anyone know of any good online courses, videos, or reference material that can help me get started? I would like to learn more about everything a design plan should entail; level of detail, which information goes on which sheet, things of that nature. The state requirements in my state are very general, and I would like to learn more about what all should be included in and how to organize electrical plans.
