JOURNEYMAN ELECTRICIAN EXAM REVIEW
COURSE DESCRIPTION:
Preparation for journeyman electrician licensure with emphasis on
calculations and the National Electrical Code.
COURSE LEARNING OBJECTIVES:
The student will compute the circuit sizes needed for the installation of
branch circuits, feeders, and service entrance conductors; explain the proper
installation of wiring devices according to electrical codes; demonstrate
grounding methods; install ground fault circuits; and identify residential
wiring methods.
