OBJECTIVES 1. DEVELOP AN UNDERSTANDING OF, AND AN APPRECIATION FOR, THE ADEQUATE WIRING OF THE SUCCESSFUL OPERATION OF ELECTRICAL EQUIPMENT. 2. DEVELOP CERTAIN SKILLS IN WIRING. 1

OBJECTIVES CONTINUED CREATE A DESIRE TO GAIN KNOWLEDGE IN THE USE OF PROPER WIRE SIZE, CIRCUIT PROTECTION, AND WIRING DEVICES WHICH CONSTITUTE A SAFE WIRING JOB. 4. INCREASE KNOWLEDGE OF ELECTRICAL USAGE WHICH WILL PROMOTE ADDITIONAL COMFORT AND LABOR SAVING EQUIPMENT IN THE HOME AND ON THE FARM. 5. PROMOTE LEADERSHIP ABILITY BY DISSEMINATING INFORMATION ON ADEQUATE AND ELECTRICAL EQUIPMENT USAGE.

CONTEST MAKE-UP THE CONTEST CONTAINS FIVE PARTS: 1. WRITTEN TEST ON ELECTRICITY, MOTORS, AND ELECTRICAL WIRING. 2. IDENTIFICATION OF ELECTRICAL COMPONENTS 3. WIRING DIAGRAM SHOWING CERTAIN DEVICES WIRED TO FUNCTION PROPERLY. 4. WIRE CERTAIN DEVICES ACCORDING TO THE NATIONAL ELECTRICAL CODE. 5. DESIGN A WIRING PLAN FOR A KITCHEN, UTILITY ROOM, OR SHOP.

GENERAL RULES b A TEAM WILL CONSIST OF 3 OR 4 MEMBERS WHO WILL WORK INDIVIDUALLY THROUGH THE CONTEST. EACH MEMBER WILL TAKE THE WRITTEN TEST AND ONE MEMBER WILL BE RANDOMLY ASSIGNED TO ONE PRACTICUM. IT WILL BE NECESSARY FOR ALL TEAM MEMBERS TO BE COMPETENT IN ALL AREAS OF THE CONTEST. b WIRE AND DEVICES WILL BE PROVIDED. TEAM MEMBERS WILL PROVIDE THEIR OWN TOOLS. THE FOLLOWING ARE RECOMMENDED.

PRACTICUM DESCRIPTION b PRACTICUM 1 - DIAGRAMING CIRCUITS b ONE MEMBER OF EACH TEAM WILL BE GIVEN A PROBLEM STATING HOW CERTAIN DEVICES ARE TO BE WIRED ACCORDING TO THE NEC. THE DEVICES WILL BE SHOWN AND THE CONTESTANT WILL BE ASKED TO DRAW THE CIRCUITS SHOWING THE CONNECTIONS TO EACH DEVICE SO THEY OPERATE PROPERLY. CARE SHOULD BE TAKEN TO SHOW THE CONNECTIONS CLEARLY AND ACCURATELY. COLORED PENCILS WILL BE PROVIDED TO REPRESENT THE DIFFERENT COLORED WIRES, AS SHOWN IN THE NEXT SLIDE.

COLOR DESIGNATIONS b BLACK = ENERGIZED WIRE b RED = ENERGIZED WIRE b BLUE = NEUTRAL b GREEN = GROUND
