Title: UNIT: ELECTRICAL SWITCHES AND RECEPTACLES


1
UNIT ELECTRICAL SWITCHES AND RECEPTACLES
  • W. C. BUSTER HOUNSHELL
  • SPRING 2002
  • Virginia Tech

2
OBJECTIVES
  • Performance Objective
  • Students will be able to identify and list the
    different types of wall switches and
    receptacles commonly use in electrical wiring
    for the home or farm stead

3
Enabling objectives
  • Given the instruction in class, laboratory, and
    assignments-
  • Students will be able to list and identify the
    different types of wall switches, receptacles and
    their parts commonly used in wiring electrical
    circuits with a 70 accuracy

4
Switches to list and identify
  • Single pole
  • Three-way switch
  • Four-way switch
  • Double switches
  • Pilot light switch
  • Switch/receptacles
  • Timer switches
  • Automatic switches
  • Motion- sensor switches
  • Programmable switches
  • Time-delay switch
  • Dimmer switch

5
Receptacles to list and identify
  • Normal receptacles
  • 15 amps, 125 volts
  • 15 amps,125 volts
  • (grounded)
  • 20 amps, 125 volts
  • 15 amps, 250 volts
  • High voltage
  • 30 amps 125/250 volts
  • 50 amps, 125/250 volts

6
Interest approach
  • The uses of electricity are numerous and new
    developments are appearing nearly daily.
  • Electricity provides our homes, farms,
    businesses and industries with valuable resources
    that would otherwise be unavailable to us.
  • Science, medicine, transportation and even
    communications have been fortunate to make rapid
    technological advancements related to our
    understanding of electricity.

7
Interest approach (Continued)
  • All phases of modern agriculture depend on the
    benefits of electricity
  • To better understand and benefit from the
    application of electricity
  • There are basic principles that one should become
    comfortable with.
