NOTE
i
Conductors must always be within CMA limits of
wire barrel.
A. Condition 1
See Figure 2, Detail A
Maximum CMA fill for copper conductor should not
exceed 40% of total CMA. For example, six No. 14
solid aluminum 12.14 mm² [24,000] Cir Mil plus one
No. 8 stranded copper 8.10 mm² [16,000] Cir Mil
equals 40,000 Cir Mil. The one No. 8 stranded copper
conductor is approximately 40% of total CMA
20.24 mm² [40,000] Cir Mil being crimped.

D. Condition 4
See Figure 2, Detail D
Four identical rectangular conductors, where one
conductor thickness is equal to or greater than 1/4 the
width of one conductor, may be crimped without
removing film insulation.
E. Condition 5
See Figure 2, Detail E
Two identical rectangular conductors, where
thickness of one conductor is equal to or less than 1/4
of the width of one conductor, may be crimped
without removing film insulation.
F. Condition 6
See Figure 2, Detail F
In some instances, it may not be possible to fit a
particular CMA loading into the normally
recommended terminal or splice. In these cases,
where seven or more equal round, or a combination
of solid aluminum and stranded copper conductors
are used, and the total CMA is at least 50% of
maximum CMA of the next larger size terminal or
splice, the larger size may be used. Example: three
No. 14 solid conductors equal about 6.07 mm²
[12,000] Cir Mils. This falls within the CMA range of a
12–10 terminal or splice accepting a maximum CMA
of 6.63 mm² [13,100] circular mils. However, it may
not be possible to insert all three conductors into the
recommended terminal or splice. It is possible to
insert all three conductors into a No. 8 size terminal or
splice accepting a CMA range of 6.63–10.52 mm²
[13,100–20,800] circular mils. The 6.07 mm² [12,000]
circular mils amounts to 59% loading of the maximum
CMA for No. 8 size terminal or splices. Therefore, No.
8 size terminals or splices may be used.
G. Condition 7
When using a variety of solid conductor sizes, none of
the conductors should vary more than one (1) wire
gage. (Ideally not more than 1/2 wire gage.)

B. Condition 2
See Figure 2, Detail B
A maximum of ten equal size round conductors may
be crimped without removing film insulation.
C. Condition 3
See Figure 2, Detail C
A maximum of six equal size square conductors may
be crimped without removing film insulation.
2.4. Wire Preparation
NOTE
Do not use stranded aluminum wire.
i
1. Select the proper terminal or splice wire size
and crimping head combination for the wire size
being used. See Figure 3.
2. Determine correct terminal or splice wire loading
by referring to Paragraph 2.3, and CMA range
listed in Figure 3.
3. Strip stranded copper wire to dimension
indicated in Figure 3.
