Aluminum Dual Rated Mechanical Connectors
A new generation in mechanical connector performance.
Cool running over 500 heat cycles. Versatile, simple to use and low cost.
Introduction
CMC®
introduces PosiGrip
®
aluminum dual-rated mechanical connectors. The PosiGrip
® line is designed to meet the rigorous
requirements of 486B and CSA 1165A specifications covering connectors for use with aluminum and copper conductors.
The PosiGrip® line is fully listed by Underwriters Laboratories, Inc. and Canadian Standards Association. In addition, these
connectors are EU RoHS compliant.
Low Resistance Design
Low initial contact resistance is the key to long life for any electrical connection and is the major element in meeting the
demanding performance requirements of UL 486B. Connector Manufacturing Company’s engineers have incorporated special
new design concepts into the PosiGrip® line. Uniquely designed I-Beam bodies and conductor hole configuration along
with specially designed and treated screws; minimize high resistance connector failures due to thermal expansion, creep,
and insufficient clamping force. The superior gripping action of the I-Bean design allows the set screw to separate conductor
strands and break down inner stand oxidation even on compressed and compact aluminum conductors. Therefore, superior
performance and long connector life are assured regardless of the type of conductor being used.
Versatility
Each PosiGrip® connector will accommodate a wide range of aluminum or copper conductor sizes of concentric, compressed
or compact configurations. Only eleven connector sizes cover the range from #14 thru 1000 kcmil. In addition, they are UL
listed and CSA certified for use with conductors having thermal insulation ratings of 90
°
C or less. This means greater flexibility
in the type of conductor being used, less inventory to carry and fewer call backs because the installer doesn’t have the right part.
Easy to install; all you need is a screwdriver or an allen wrench.
Quality Assurance
To identify UL 486B connectors, UL requires such connectors to be marked CU9AL when listed for use with 90
° C rated
conductors. To be sure that the connector you buy meets all UL requirements, CMC
®
inspects each lot of PosiGrip® connectors
for integrity of physical dimensions, aluminum properties, set screw and conductor hole alignment, plating, along with screw
and body thread class. Only connector lots meeting industry accepted quality levels are approved for shipment.

Lug Features
1. The unique ridges formed on the bottom of the contact surface are designed to provide positive contact points for an
electrically secure joint of the lowest resistance for current flow. Just as a tri-pod provides tilt free contact on a smooth
surface, this connector is designed to cause specific contact points where current can flow without “hot spots” created when
two flat surfaces are joined together.
2. The screws used to clamp the conductor are designed to extend beyond the barrel sides of the connector to allow a better,
more secure compression of the conductor. This design spreads conductor strands to help dis sipate heat. In addition, this
causes the maximum conductor to spread slightly more than the wire way opening which when installed improves its pull out
safety features and capabilities.
3. The design of the wire way opening allows the conductor to enter the lug at the lowest point possible near the tang of the
lug to provide optimum transfer of current creating a straight line flow through the connec tor for the least possible path of
electrical resistance. A positive wire stop is provided with a step in the connec tor tang.

Notes
www.cmclugs.com 513.860.4455
CMC® is proud to supply the industry with a line of electrical connectors fabricated from the very best
aluminum alloy, 6061-T6. This choice was predicated upon many design factors to achieve the best
balance between strength and conductivity. Both factors are of extreme importance in connector design
calculations. The aluminum extrusions have almost a two-to-one advantage in yield strength to that of a
sand cast alloy 356 or die cast alloy AXS679, permitting an extra margin of safety while the conductivity
is a most favorable 43% IACS.
The set and socket screw mechanical connectors are designed to utilize the advantages of the 6061-
T6 alloy temper for high yield strength while providing a connector of low stress. Screw pressure is
designed to break through aluminum conductor oxide by cold flow process that ensures a low resistance
connection. Sufficient pressure is maintained on the conductor to prevent the reforming of the aluminum
oxide. The pressure, combined with the high conductivity factor, will result in a connector operating
temperature below that of the conductor.
We therefore, offer these advantages in connector design:
1. Compact design
2. High strength aluminum
3. Relative light weight construction
4. Economic
5. Tested products in accordance with the Underwriters Laboratories and the Canadian Standards
Association requirements for listing.
These factors together with our dedication for the highest quality standards available and an unsurpassed
service level, provide our customers with maximum reliability.

Connector Manufacturing Company® fabricates the best in electrolytic copper electrical
connectors. Copper connectors are formed from 100% pure electrolytic copper to eliminate the
effects upon conductivity when alloys are utilized to reduce costs.
CMC® copper connectors are either extruded from pure electrolytic copper or formed from copper
tubing carefully shaped to size. They may also be produced from copper strip which is used to
form the tang or bus connection. These light weight connectors will perform better than many of
the heavier, bulkier cast copper alloyed products on the market. This saves the customer the cost of
metal, freight and space, while gaining top conductivity.
We therefore, offer these advantages in connector design:
1. Compact Design.
2. High Strength - low heat rise copper.
3. Relatively light weight construction.
4.
Economy and efficiency.
5. Tested products in accordance with Underwriters Laboratories and the Canadian Standards
Association requirements for listing.
These features together with our dedication for the highest quality standards available and an
unsurpassed service level, provide our customers with maximum reliability.

The number of outlets, outlet spacing and mounting hole locations can
be established according to individual requirements.
When ordering
neutral bars please add a suffix to indicate the number of usable
wire ports required. Ex: NA30-8 would result in an NA30 style
neutral bar with eight (8) wire ports.

1. Measure the length of the wire hole in the connector, with a measuring device.
2. Measure and mark the conductor cable approximately 1/4” longer than the connector.
3. Strip the insulation from the cable with an appropriate stripping tool; be careful not to damage the
conductor wire while performing this operation.
4. If the wire cable (conductor) is corroded or blemished in any way, clean the exposed end of the cable
with emery cloth or wire brush dependent upon the severity of the corrosion to remove oxides from the
surface of the conductor.
5. Prior to installation of the conductor to the connector, apply a generous amount of oxide inhibitor to the
bare portion of the conductor.
6. Rotate the conductor back and forth to evenly distribute the inhibitor.
7. Install the conductor into the connector leaving approximate 1/4” of exposed conductor visible. Be sure
the installed conductor is equal in length of the wire hole. Snug with an Allen wrench.
8. Torque the set screw to the recommended value with a torque wrench. After a minute, retighten the
screw again to the recommended torque value.

For optimum efficiency, it is necessary that the correct bolt, nut, and washer combination be used with the correct
combination of conductor materials. This table shows acceptable methods of joining different combination of bus bar.
Where different combinations of metals are being joined, a follow-up device such as a conical pressure washer is usually
recommended if one, or both, bus materials are soft drawn aluminum. If both bars are hard drawn, large flat washers will
suffice regardless of the bolt materials.
Other considerations which should be taken into account when selecting hardware are corrosion and vibration. For
example, if severe corrosion is anticipated, non-corrosive materials such as stainless steel or silicon bronze, should be
selected in preference to galvanized steel. If vibration is anticipated, the use of locking washers should be considered.
Methods of Joining Bus Bars
Bar Connections:
The Tang of a compression or mechanical connector is a bus bar, which connects to another bus bar. If you remember the
rule about wire brushing and using joint compound with bare (unplated) aluminum, you cannot go wrong. Plated parts
should be cleaned with a solvent if they are dirty, but never abrade or otherwise disturb the plating! Figure shows a typical
bar connection and the type of hardware used.
Contact surface must be clean. Use a joint compound with bare aluminum. Conical pressure washer is usually
recommended if one, or both, bus materials are soft drawn aluminum.
(1) Denotes preferred hardware usage.
Note: Contact sealant recommended between aluminum to aluminum and alumi-
num to copper connections unless other protective measures are taken.
