Competency: 203.00Draw Electrical Plans Objective: 203.05 Identify terms and symbols used to indicate electrical fixtures. Objective: 203.06 Demonstrate the rules and standards for electrical fixture placement.
Switches • Single pole • 3 way • 4 way • Weather proof • Dimmer • Special • Branch circuits/Switch leg connectors
Convenience Outlets • Duplex receptacle • Split wired • Special purpose • 220volt • Weather proof • Ground Fault Interrupt (GFI)
Lighting • Incandescent • Fluorescent • Special • Recessed
Verify Fixture Placement • Outlets • Lights • Switches and switch leg connectors • Miscellaneous fixtures • Exhaust fan • Ceiling fan • TV • Telephone • Smoke detector • Chimes/Bells/Buzzers
Miscellaneous • Exhaust fan • Room air circulating fan • Telephone • TV antenna outlet • Chimes • Smoke detector • Thermostat
Placement of Switches • Each room MUST have at least one light controlled by a switch • Latch side of door/entrance • Outside of closets • Hallways, stairs, garage lighting controlled from both ends (3-way) • Multiple switches for large rooms (3-way)
Placement of Outlets • Furniture/Appliance Considerations • Living & Service areas • One outlet per 6’ of wall • No further than 6’ from each corner • Kitchen area • One outlet per 4’ of wall • Each appliance should have an outlet • Hallways • Every 15’ of wall
Placement of Outlets • Bathrooms • At least two outlets • One above sink or counter • Weatherproof outlets • Each side of exterior • Position for decorative lighting • At least one outlet in attic & crawl space • Ground Fault outlets • Near water sources
Placement of lights • Sufficient foot-candles for each room • Illumination for desired activities • Lighting over dining table • Exterior • General illumination and decoration • Motion detectors for security • Waterproof • Lighting for stairs and halls
Electrical Fixture Plan • Shows approximate fixture placement • Circuit design not included • Electrical loads not considered • Fixtures may be shown on Floor Plan • Avoid crowding • Using CAD • Layers created for various details
Electrical Symbols • Drawn in approximate locations • Standard placement • Switches = 48” high • Outlets = 12” high • Note dimensional changes with symbol when placement varies from standard
Electrical Symbols • Connect symbols for switches to fixtures with switch leg connector symbol • Provide symbol legend • Dimensions not provided except in special situations
