nut. When a
terminal is attached to an equipment item
with a screw, the screw shall be passed
through a lockwasher, a plain washer
and the terminal(s) in sequence with the wire
terminal against
the attachment point on the equipment. Refer to Figure 204.

Wire Repairs
A. General Instructions.
(1) Replace broken,
frayed, cracked
or damaged wire with
new wire. The entire
wire segment should
be replaced. Replacement wire segment must be size and type indicated on the applicable
wiring diagram.
If wire or cable damage is limited to
outer covering only, wire or cable may
be
repaired
as outlined in
this section.
CAUTION: DO NOT
SPLICE, SOLDER OR TAPE
DAMAGED WIRE UNLESS
INVESTIGATION PROVES
THAT SYSTEM INTEGRITY
WILL NOT
BE AFFECTED.
DO NOT USE SMALLER
SIZE WIRE. USE OF
SMALLER SIZE WIRE
CAN RESULT IN BURNED
WIRING OR
MALFUNCTIONING
EQUIPMENT.
B. Braided Nylon Insulated Wires.
(1) Clean area to be repaired with aliphatic naphtha.
(2) Lay loose nylon strands as evenly as possible over damaged area.
(3) Spiral wrap double layer of vinyl tape over damaged area, overlapping 1/2 width of tape. Tape
should extend at least one inch beyond both ends of damaged area.
(4) Tie both ends of tape
with nylon cord and brush knots
with clear lacquer.
(5) Small gage
wires may be wrapped with
adhesive vinyl tape.
C. Chromel/Alumel Thermocouple Wire.
(1) Clean damaged area with solvent.
(2) Lay loose fiberglass covering
ends as evenly as possible over
damaged area.
(3) Tension spiral wrap
double layer of glass fabric tape (Permacel
EE-3343) over damaged area,
overlapping 1/2 width
of tape. Tape should extend at least
one inch beyond both ends of
damaged area. Maximum length of taped area should be no greater than 3-1/2 inches.
(4) Cure tape in place by heating
with heat gun or lamp to approximately
320°F for 30 minutes.
Protect
adjacent wires from heat by
covering with heat resistant
material.
(5) The ends of the outer insulation
which has been stripped back and
trimmed on the thermocouple
leads should be served from
the ends of the insulation back to
approximately 1/2-inch by
wrapping cord as shown in Figure 205.
D. Splicing Electrical Wires. Splicing of wires is not recommended; however, in some cases, splicing of
wires may
be necessary.
(1) Refer toSplices and Terminals for splices and tools.
(2) All splices shall be covered with
an insulating sleeve and secured. Preinsulated
splices need
not be covered by an additional sleeve as long as the splice is completely covered.
(a)
The splice crimping tool for preinsulated
splices has an insulation crimping adjustment
set
to 1,2, 3 or 4 depending on
the thickness of insulation. The splice
should have a firm crimp
on insulation without damage.
(3) Splices
in the same wire group or bundle shall be
staggered to prevent excessive enlargement
of the group or bundle.
(4) Aluminum cables shall not be spliced.
(5) Splicing Shielded
Wires. Refer to Figure
206.
(a) Refer toSplices and Terminals for splices and tools.
(b)
Splices in the same wire group or
bundle shall be staggered to prevent
excessive
enlargement
of the
group or bundle.
(c) Splices shall not be located under
a clamp or in a place where the wire
bundle is flexed,
such as at
a wire bundle breakout
to an instrument.
(d) Stagger inner conductor splices as shown in Figure 206.
(e)
After installing braided solder sleeve
the solder shall be completely melted
and
environmental seal bands
must make contact with the outer
jacket of the wire.
