The goal of this competition is for students to demonstrate their electrical wiring skills by correctly identify electrical devices, choosing the proper wire size for a 15 Amp rated branch circuit, and wiring an electrical circuit that contains 2 three-way light switches, a keyless lamp holder, and one receptacle outlet. All electrical components will be provided along with the 120 V power source and board.
The project will be graded on speed, quality of splices/terminations, and functionality.
• Appropriate plastic device boxes will be mounted on a 2 ft X 2 ft plywood board with wiring being nonmetallic sheathed cable, type NM-B (romex). Per residential wiring standards.
• Installation shall include 2 three-way switches that control a standard keyless fixture.
• Installation shall also include a receptacle outlet with constant power (not switched).
• All devices, boxes, and wire will be supplied.
• Multiple types of switches and receptacles will be provided, the students will have to identify the proper device needed for project and install them.
• NM-B cable shall be installed from power supply terminal strip, to receptacle, to three-way switches, to light.
• All wire-to-wire terminations shall be pre-twisted and capped with a wire nut per industry standards.
• All wire to device connections shall be hooked and attached to device screw per industry standards.
• Speed of Installation
• Quality of splices and connections
• Neatness of work
