BLD-2130 NCCER Electrical Level 3

Credits 7
This course provides the third level of training of the National Center for Construction Education & Research (NCCER) electrical curriculum, which is designed to comply with the National Electric Code (NEC). Students gain an understanding of lighting system design and commercial electrical service. They acquire the skills and knowledge required to perform load and conductor calculations and to prevent explosions and ignitions in hazardous locations. They learn how to install and perform maintenance tasks for overcurrent protection, distribution equipment, transformers, voice, data and video, and motor controls. Successful completion of the course earns students the NCCER Electrical Level 3 credential. This course is cross-listed with the following Continuing Education courses: ELC 346: Electrical: Level 3, Part 1 AND ELC 347: Electrical: Level 3, Part 2 AND ELC 348: Electrical: Level 3, Part 3.
Prerequisite(s): BLD-2120
