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

• Western Union Short-tie Splice

• Aerial Tap

• Western Union Long-tie Splice

• The Britannia joint

This is the most widely used splice or joint 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

• Y-Splice

• The Britannia joint

This method of wrapping is generally used on small cables because the strands are flexible and all can be wrapped in one operation.

• Western Union Long-tie Splice

• Y-Splice

• The Britannia joint
