Course Objective
Faulty wiring causes most electrical fires. To prevent these fires, selection of proper wire type, size, and even color, is required by the National Electrical Code. This course concentrates on the range of wire and cable applications used in industrial plants and facilities. Wire connection and splicing methods are also discussed.

Benefits
Builds confidence and pride of workmanship
Cooler and safer electrical wiring

Activities
Wire size and insulation identification
Cable sizing exercise
