T-splice

A simple T-splice in wire

The T-splice is a splice that is used for connecting the end of one wire to the middle of another wire, thus forming the letter "T." This splice can be used with solid or stranded wires. The existing wire is called the main wire. The new wire that connects to the main wire is called the branch wire or tap wire.^[1] This is a prevalent junction type used in knob and tube wiring.

Procedure

The T-splice is made by stripping about 3/4 of an inch from the main wire and the end of the branch wire. Then wrap the branch wire around the main wire 4 to 5 times. Cut the loose ends. Solder and tape the connections.
