Electricity: Residential Wiring

This training details the National Electrical Code 1996 changes, explains building inspections, service inspection, rough and finished installation, and introduces symbology, wire gauges, and wire color code. It highlights planning the location of service panels and details installation of electric feed from the Electric Company, to the meter base, to the service panel. The various voltage ranges and outlet types are presented and roughing in and finish installation of outlets are detailed. Lastly, the installation of various switches and switched circuits are detailed such as single, three-way, four-way, timer, dimmer, motion and time delay.

Training for anyone involved in the installation and repair of household electrical wiring.
