Wiring Methods, Materials, and Code

Most people who are new to electrical work learn wiring by doing it. They pick up habits from whoever trained them, repeat what seems to work, and only consult the code when something gets flagged on an inspection. This course takes a different approach. It starts at the foundation: what conductors are made of, how they're rated for heat and current, and which cable types belong in which environments. From there, you'll learn how to actually use the National Electrical Code — not memorize it, but navigate it. You'll know which articles govern branch circuits, overcurrent protection, grounding, and general wiring methods, and you'll be able to find a specific answer in the field without guessing.

The second half of the course moves from rules to application. You'll work through boxes, devices, and connections — including box fill calculations and torque specifications that most people skip until something fails. Then you'll apply all of it to a complete residential installation: sizing the service entrance, laying out a panel, wiring kitchens and bathrooms, adding dedicated appliance circuits, and reading a panel schedule from start to finish. By the end, you won't just know what the code says. You'll understand why it says it, which is the difference between someone who follows rules and someone who can work through a problem they haven't seen before.

This course is built for people entering the electrical trade, apprentices who want to fill in the gaps their on-the-job training left, and anyone in a related field — construction management, inspection, design — who needs to speak the language of electrical work with accuracy. You don't need prior electrical experience to start, but you should expect to think carefully and work through calculations. The concepts build on each other, and the goal is competence, not just familiarity.
