What is the primary code book used for the Colorado Journeyman Exam?

The primary code book used for the Colorado Journeyman Exam is the National Electrical Code (NEC). This code serves as the primary standard for electrical installations and safety practices in the United States, including Colorado. The NEC outlines critical guidelines for electrical wiring, grounding, overcurrent protection, and the installation of electrical equipment, ensuring that all installations are safe and compliant with recognized standards.

While other codes, such as the International Building Code or Uniform Plumbing Code, deal with different aspects of construction and public health, they are not the focus of the Journeyman Electrical Exam. The Local Electrical Code may also apply to specific jurisdictions but is typically based on the provisions of the NEC, making the NEC the foundational reference for electrical professionals in the state.
