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.

PosiGrip

® 

 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.
