Common Splices and Joints

It is used to join two or more conductors inside the junction box

• Rat Tail

• Knotted Tap

It is used on small cables because the strands are flexible and all can be wrapped in one operation

• Aerial Tap

• Y-Splice

It is used where the splice is subject to strain or slippage

• Knotted Tap

• Duplex Cross Joint

It is used where the tap wire is under considerable tensile stress circuit

• Plain Tap

• Aerial Tap

It is used as a temporary tap usually done in constructions sites.

• Plain Tap

• Aerial Tap

It is used where the two tap wire is under heavy tensile stress

• Wrapped Tap

• Duplex Cross Joint

It is used on large solid conductors where it is difficult to wrap the heavy tap wire around the main wire

• Y-Splice

• Wrapped Tap

It is used in interior wiring installation to extend the length of wire from one point to another

• Western Union Short-Tie Splice

• Western Union Long-Tie Splice

It is used extensively for outside wiring to extend the length of wire from one end to another

• Western Union Short-Tie Splice

• Western Union Long-Tie Splice
