INSTALLATION INSTRUCTIONS
for Pin Adapter (Type PA)
GENERAL INFORMATION:
The Pin Adapter is designed to provide reliable termination of
stranded aluminum conductors with insulation rated not more
than 90° C (194° F) in mechanical connectors listed for Al-Cu
use and connectors suitable for stranded copper conductor
installed in accordance with the National Electrical Code.
Reliability is obtained by terminating the aluminum conductor
in one end of a compression aluminum sleeve, the other end
of which has a factory installed copper pig-tail. The copper
end is then installed in the mechanical connector.
The following installation instructions are provided as a
means of assuring the electrical equipment and its mechanical
connectors, into which Pin Adapter is to be installed, are
physically compatible with the dimensions of the Pin Adapter.
They should be read carefully before installing the Pin Adapter
in electrical equipment.
INSTALLATION A:
Pin Adapter for use with listed connector, marked Al-Cu
and for use with connectors in electrical equipment
marked to indicate its suitability FOR USE WITH
ALUMINUM WIRE.
1. Select the Pin Adapter marked for the aluminum wire size
to be terminated.
2. Check the copper pig-tail length against the equipment
connector to be sure sufcient contact is made with the
pressure plate or set screw in the mechanical equipment
connector. Do this with the mated insulating cover
(600V 90° C) supplied, in place over the Pin Adapter.
WARNING
RISK OF SHOCK, DISCONNECT
POWER BEFORE INSTALLATION.
CAUTION
This adaptor is to be used only in accordance with the
limitations of clearance and bending radii as specied in the
following instruction. It is recognized that there is equipment
within which this adaptor cannot be use in accordance with
these instructions.
4. Check wiring room leading to the mechanical equipment
lug to be sure use of the Pin Adapter will not reduce the
minimum wire bending space required by Table 312.6(A)
of the National Electrical Code**. (Measured without cover
installed as shown in Step 5).
National Fire Protection Association.
5. Bend cable to t in equipment before installing the Pin
Adapter. (Check wire bending space from Adapter rear to
inside face of housing or nearest obstruction.Measurement
is perpendicular to the rear of Adapter).

Copper Pig-Tail
3. Check diameter of mated insulating cover to assure that
there is no interference in any direction when it is installed
CAUTION
DO NOT INSTALL the Pin
Adapter in opposite holes if
mated insulating covers are closer
together than shown. Spacing
must be more than 1/4" for 300V
or less and more than 1/2" for
301-600V.

6. Strip insulation to length of compression barrel as shown
in table in column "A" to permit full insertion of wire.
Scratch brush the aluminum conductor before installation.
Select appropriate tool and dies as shown in the table, and
make the required number of crimps.
7. After installing the Pin Adapter on the conductor, slip the
insulating cover completely over the compression barrel.
Use of the insulating cover assures that minimum electrical
spacing will not be violated.
8. Insert pig-tail fully into connector body and tighten set
screw to equipment manufacturer’s recommended torque
(if no torque recommendation is provided, tighten to
recommended values given in table).

INSTALLATION B:
Pin Adapter for use with listed
connectors and with connectors in UL
listed equipment, SUITABLE FOR
COPPER WIRE ONLY.
(NOTE: UL listed connectors and
electrical equipment suitable for copper
wire only do not bear marking to indicate
such use.)
1a. Determine equipment,
rating(ampacity) and/or ampacity
service required for the specic
connector.
1b. Based on (a), determine copper wire
gauge size that normally would be
selected.
1c. Select appropriate Pin Adapter and
the associated catalog number for
insulation by locating the required
COPPER wire size and the table
titled "Catalog and Specication
Information."
2a. Continue with steps 2 through 8 as
above.
NOTE: Referring to step 5 — installer
is cautioned to assure that the use of
Pin Adapter in UL listed equipment
will provide a full minimum wire
bending space.

HOW TO MAKE A GOOD
ALUMINUM CONNECTION:
Insert the conductor all the way into
the barrel and using the proper die
(see chart) crimp the connector.
1.
Select Pin Adapter marked for the
wire size to be used.
NOTE: Overlap crimps are to be made
between knurl or ink marks. Multiple
crimps are to be made adjacent to
each other between knurl or ink
marks. Make sure that the connector
is used with a die that matches the die
index, code number or color marked
2.
Do not nick or ring the conductor
on the connector.

5.
Use circumferential or hex dies.
Compress from base of socket toward
3.
Remove oxide lm with wire brush
from the stripped portion of the
conductor.
