General
NOTE: This instruction sheet outlines the recommended
installation procedure. Use of these lugs in some instal-
lations may result in less wire bending space than is
specified in the National Electric Code.
Installation of Compression Connector
A. Turn off power supplying device before installation com-
pression lugs.
B. Remove any existing wire connectors from circuit breaker.
C. Install circuit breaker.
D. Preform cables to final configuration and strip insulation
back 11/,6 in. on each conductor. Use an appropriate
insulation stripping tool to avoid damaging the conduc-
tor. (See Figure 1.)
H. Select an appropriate tool and die combination from
Table 1 and make the required number of crimps within
the boundaries stamped on the connector barrel. Refer
to Figure 2 for sequence of multiple crimps.

E. Clean aluminum conductor surfaces thoroughly with a
wire brush or other suitable means, to remove oxides
and other contaminants from the conductor.
NOTE: Copper wires and the compression connector should
not be cleaned abrasively.
F. Remove cap from compression connector and insert
cable fully into barrel (1) (Figure 1) of connector
G. Insure that connector tang(s) (2) (Figure 1) are in their
proper orientation prior to crimping. This helps avoid
twisting of cables during installation.
Figure 2
I. Remove any inhibitor compound expelled during the
crimping operation from the connector body and the
cable insulation .
J. Slip insulating cover over connector tang and then over
connector barrel so that only the connector tang is
exposed (Figure 3).
Warning: Short spacings will result if Step J is not followed.

K. Position connector tang on top of the circuit breaker
terminal pad and secure with 3/8-16 x 1 1/2 in. socket
head cap screw and conical spring washer. Conical
spring washer is to be installed with convex side of
washer toward underside of screw head (Figure 3).
Torque screw to 228 in-lb.
NOTE: If only using one lug for proper ampacity, insert spacer
supplied with kit between spring washer and compres-
sion lug.
