The knot needed is the single sheet bend knot using all four conductors. It is easy once
you have practiced several times. At this time, if you have access to the equipment, get a 2-foot piece of
WF-16/U and tie a knot in the center so the four wires stay together. Make a small loop at one end.
Take the other end and place it over the top, then under and over the wires and down through the loop
and pull it tight. (See Figure 2-7.)
Secure the knot with tape. Practice that tie until you can do it without thinking. It is not
important to tape it each time you make it. You will only tape it when you are ready to continue splicing
Figure 2-7. Tie single sheet bend.
At this time you should be ready to do a complete splice. Make the single sheet bend knot, but
this time have at least 6 inches of the end available. The ends could be shorter, 3 inches. The extra
length allows for error. Split each pair of conductors back 3 inches. Be careful not to damage the wires.
Remove 3 inches of insulation from each end of the wires. Remember, now you are working with four
wires on each end. The colors are important. Connect one green wire to its opposite green wire with a
square knot. Tape the bare wires. Now connect the other green wires the same way. There should be
the brown wires to connect together. Do those the same way you did the green wires. Once you have
all four wires spliced and taped, you now put those taped wires together with the tape on the single sheet
bend knot and tape it all together. (See Figures 2-8, 2-9, and 2-10.)
