Computing Circular
Mil Area
For best results, the proper
AMP terminal or splice must be
selected not by the “fit” of wire or
wires in the terminal barrel, but
by the total circular mil area in
cross section of the wires used.
For this purpose AMP has pre-
pared convenient tables to assist
in the calculation of circular mil
areas. When the totals are
known, the proper AMP terminal
or splice can be determined
quickly.
Unusual combinations or special
applications should be submitted
to AMP engineering department
for size recommendation. In any
application, the careful selection
of terminals by the circular mil
area method will insure the high-
est possible performance, both
electrically and mechanically, in
your AMP terminations.
Example of multiple wire
configurations used in one
termination
ALWAYS SELECT TERMINALS
BY THE CIRCULAR MIL AREA
METHOD. For example, a No.
18 AWG 16-strand conductor
(1600 CMA) and a No. 16 AWG
19-strand conductor (2426
CMA) will have a combined total
of 4026 CMA. This total CMA is
equivalent to a No. 14 AWG
conductor.
