General Application
Guidelines
To assist you in obtaining
the optimum COPALUM
insulation piercing crimp
termination for solid copper,
solid aluminum and strand-
ed copper in the same wire
barrel, the following guide-
lines regarding size, num-
ber and total CMA of con-
ductors being terminated
are recommended:
1. A maximum of 10 equal
size round wires, or a
maximum of 6 equal
square wires may be
crimped without insula-
tion removal.
2. Four rectangular wires
(where T
≥ 1/4W) or 2
rectangular wires (where
T
≤ 1/4W) may be
crimped without insula-
tion removal.
3. When crimping different
size solid conductors,
size should not vary by
more than 1 wire gauge,
and preferably by no
more than 1/2 wire
gauge.
4. To use parallel splices
with round magnet wire,
the CMA of the lead wire
should be less than the
sum of the magnet wire
CMA, and the total num-
ber of conductors (lead
and magnet) must be
less than six.
5. To use a butt splice
when the lead wire CMA
is
≥ the combined mag-
net wire CMA.
6. In a solid (or combina-
tion of solids) aluminum
and stranded copper
application, the maxi-
mum amount of CMA fill
for the copper conductor
should not exceed 40%
of the total CMA being
crimped.
7. Due to the closed barrel,
it may not be possible
for a particular CMA
loading to fit in the nor-
mally recommended
connector. In instances
where 7 or more equal
round conductors or a
combination of solid alu-
minum and stranded
copper is used, and the
total CMA is at least 50%
of the maximum CMA of
the next larger size con-
nector, this larger size
connector may be used.
8. For applications using
wire combinations not
covered by guidelines
above, consult
Tyco Electronics
Engineering.
Warning: Not approved for
reconnection of residential
aluminum branch circuit
wiring. (Refer to Catalog
82205.)
