Pigtail Splice

Category: infrastructure

A wiring technique where multiple circuit conductors are joined together with a short extension wire using a twisting wire nut connector.

Pigtailing prevents a single device failure from breaking the whole circuit down the line. Instead of running incoming and outgoing hot wires directly through a receptacle's terminal screws, the wires are spliced inside the box with a third "pigtail" wire feeding the individual outlet plug.

Common Examples

• We utilized a tight pigtail splice inside the deep device box to keep the continuous neutral line intact for the downstream outlets.
• Executing a clean pigtail splice ensures that removing a single broken outlet plug will not inadvertently kill the rest of the branch run.
