Electrical installation is one of the primary duties of electricians across Kentucky. Ensuring sufficient and efficient electrical service in homes, offices and more requires mastery of the NEC. This course is approved by the Department of Housing, Buildings and Construction to teach students the standards of NEC-2023. Work safely to provide power across the state.

This course is organized to show electricians how the elements of the NEC work together for safer installations that meet electrical demands. Many codes have changed from NEC-2020 to NEC-2023. This course is up to date on every new addition and alteration. A “cut-and-paste” comparison shows you exactly where changes have been made in an easy-to-understand format.

Sharpen your skills with a set of practical problems. Each scenario is designed to demonstrate the application of an NEC principle in the real world. Completion of these exercises will help you to successfully and safely complete installations in the field.
