What is Pig-tailing Aluminum Wiring

  As stated throughout this section, the problem with aluminum wiring is the connections. Whether the connection is good or bad usually depends on the device (Outlets and Switches)

By Pig-tailing the wiring, Connections are not dependant on the plug or switch. In plain english, the connection remains good even if the switch or plug goes bad, is removed, disconnected or whatever.

In making these connections, special Connectors are used.
