How to Safely Wire GFCI Outlets

Application: Wiring or Replacing a GFCI Outlet.
Skill Level: Beginner to Intermediate.
Tools Required: Basic Electricians Pouch Hand Tools and a Voltage Tester.
Estimated Time: Depends on personal level experience, ability to work with tools and the number of outlets that will be replaced.
Precaution: Identify the GFCI outlet circuit, turn it OFF and Tag it with a Note before working with the wiring.

Creating a Copper Pig Tail with Aluminum Wire

  • Working with Aluminum Wire
    • Special methods must be applied when working with aluminum electrical wiring in order to prevent corrosion and loose connections which can be caused by heat as a result of the amperage load which is placed on electrical circuit wiring and components.
  • Splicing Aluminum Wire
    • When installing or replacing 120 volt 15 amp or 20 amp switches and outlet receptacles where¬† aluminum wiring has been installed,¬† the aluminum wires should be spliced together and a copper wire pigtail should be added.
  • Anti-Corrosion Ointment for Aluminum Wire
    • The splice must be coated with approved AL/CU anti-corrosion ointment and approved AL/CU wire connectors of the appropriate size must be used.
  • Attaching Aluminum Wire
    The copper pig tail will then be attached to the outlet or light switch terminal depending on the device or the application.
  • AL/CU Rated Outlets and Switches
    In locations where it is allowed, aluminum wire may be attached directly to outlets and switches that are identified and labeled with the approved AL/CU wire type designation.
