Practical electrical calculations for initial design. Atomic, searchable lessons built around Ugly's Electrical References and the current NEC — each with an interactive walkthrough and a clear line on what escalates to an engineer.
New to the course? Follow this order. Each stage builds on the one before it — fundamentals first, then sizing, protection, load calcs, and equipment, finishing with the deliverable standards and a full end-to-end project. The capstone is gated: work the stages it depends on first.
