ELAP 1545 Electrical Apprenticeship 2B

This course is the fourth in a series of eight courses at the electrical apprentice level. This course meets the related apprenticeship training requirements of the State of Wyoming, Department of Fire Prevention and Electrical Safety. It is not required that students be participating in an apprenticeship program to enroll in this course, but it is recommended. The curriculum for this course corresponds to the level 1 requirements of the National Center for Construction Education and Research (NCCER). This course continues instruction in the National Electrical Code, and instructs students in the topics of cable trays, conductor terminations and splices, installation of electrical services, circuit breakers and fuses, contractors and relays, and electrical lighting. Students can expect to complete a minimum of 3 hours coursework outside of class each week. (Related apprenticeship training hours: 48 hours lecture - 48 hours outside course-work) (3 lect.)
