Figure 5-28 shows how to make a pigtail splice. Note the
two ways to end the splice. When the splice is taped. the
ends must be bent back so the sharp edges will not
penetrate the tape (fig. 5-28). When a solderless
connector is used instead of tape. the ends are cut off (fig.
5-28). When more than two wires are joined in a pigtail
splice, as shown in figure 5-29, they should be twisted
together securely before the solderless connector is put

on. Twisting the wires together first ensures that all the
wires are fastened together properly.
Western Union Splice
The Western Union splice (fig. 5-30) is used when
the connection must be strong enough to support long
lengths of heavy, wire. In the past. this splice was used
to repair telegraph wires. If the splice is to be taped,
care should be taken to eliminate any sharp edges from
the wire ends.
The T-tap (fig. 5-31) is a type of splice that allows
a connection to be made without cutting the main line.
This connection is one of the most difficult to make. A
certain amount of practice may be necessary to make
this connection look neat. Study figure 5-3 1 to
determine the proper technique in making this splice.
Portable Cord Splices
Cord splices are weak because there is no connector
to hold them together; therefore. they should be used for
emergency purposes only. If the cord must be saved, use
twist lock plugs and receptacles to rejoin the cord. Figure
5-32 shows how solid wires are spliced. The individual
splices are staggered to prevent a large bump when the
cord is taped. Additional strength may be added to this
splice by soldering each individual splice.

strain may be placed on the connection.
