Wire Splices and Joints

A joint commonly used to join two or more conductors inside the junction box.

• Aerial Tap

• Rat Tail

This is a two tap wire turned simultaneously and is used where the two tapped wire are under heavy tensile stress.

• Duplex Cross Joint

• Double - Crossed Joint

This is the most widely used splice in interior wiring installation.

• Western Union Long-tie Splice

• Western Union Short-tie Splice

This joint is used where the tapped wire is under heavy tensile stress.

• Knotted Tap

• Plain Tap

A method of wrapping generally used on small cables.

• Y Splice

• Britannia Splice

This is used where the tap wire is under considerable tensile stress circuit.

• Duplex Cross Joint

• Plain Tap Joint

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

• Western Union Short-Tie

• Western Union Long-Tie

This is used as a temporary tap usually done in construction sites.

• Aerial Tap

• Plain Tap

It is used in the same manner as the ordinary-crossed join with the advantage of being stronger.

• Double-crossed Joint

• Duplex cross joint

This splice is applied on both inside and outside of the building to big solid wire where twisting is difficult but there is an equipment to lessen the difficulty on doing this kind of splice.

• Britannia Splice

• Y splice
