Electrical, Level 1, is the first installment of NCCER's 4-level electrical curriculum. Over the course of the series, you'll learn the structure of electrical systems, while building skills to follow blueprints, install wiring and navigate other electrical components such as circuit breaker panels, switches and light fixtures. In this introductory level, you'll get an overview of the work of an electrician, including the basics of safety, codes, testing and documentation. The 10th Edition has been revised to reflect the 2020 National Electrical Code(R), bringing the training up-to-date with current industry requirements. It includes revisions to five modules, updated module examinations, and dozens of new photographs and wiring diagrams.
