1. Objective 17.02
Explain the procedure for installing switches, making common splices, and doing other electrical wiring tasks

2. Installation Procedures
Single Pole Switches:
Toggle
Rocker arm
Push button
Silent
Type depends on use and location

3. Installation Procedures
A light fixture uses two terminals
A single pole switch has two terminals
A three-way switch
Has three terminals
Uses two traveler wires
A black and a red

4. Installation Procedures
A four-way switch has four terminals and can only be installed in between two three-way switches
It has four travel wires

5. Installation Procedures
Electrical or wiring boxes musts be installed at every junction, splice, light, switch or outlet

6. Installation Procedures
Certain NEC Codes require wires to be inside conduit.
Thin conduit may be cut with a hack saw or a metal cutter saw
NM cable is installed inside buildings

7. Installation Procedures
Outdoor wire is selected based on use
UF: used to bury underground as feeder wire
USE is used to provide mechanical protection where wires enter and leave the ground
SE and SEU are used to bring electrical service into a building
TW is used to provide service in areas that have moisture

8. Installation Procedures
                                             
The wire loop should be attached to a screw terminal in the same direction the screw turns

9. Installation Procedures
A rat tail splice is used inside junction boxes
A western union splice is used where strength of the splice is required

10. Installation Procedure
Copper wire is preferred
If aluminum is used, one size larger wire must be used to carry the same electrical current
Remember the smaller the number, the larger the wire
