CONDUCTOR SPLICES AND TERMINAL CONNECTIONS
Conductor splices and connections are an essential part of any electrical circuit. When conductors
join each other or connect to a load, splices or terminals must be used. Therefore, it is important that they
be properly made. Any electrical circuit is only as good as its weakest link. The basic requirement of any
splice or connection is that it be both mechanically and electrically as sound as the conductor or device
with which it is used. Quality workmanship and materials must be used to ensure lasting electrical
contact, physical strength, and insulation. The most common methods of making splices and connections
in electrical cables is explained in the discussion that follows.
INSULATION REMOVAL
The preferred method of removing insulation is with a wire-stripping tool, if available. A sharp knife
may also be used. Other typical wire strippers in use in the Navy are illustrated in figure 2-1. The hot-
blade, rotary, and bench wire strippers (views A, B, and C, respectively) are usually found in shops where
large wire bundles are made. When using any of these automatic wire strippers, follow the manufacturer's
instructions for adjusting the machine; this avoids nicking, cutting, or otherwise damaging the conductors.
The hand wire strippers are common hand tools found throughout the Navy. The hand wire strippers
(view D of figure 2-1) are the ones you will most likely be using. Wire strippers vary in size according to
wire size and can be ordered for any size needed.
