E-Z GroundTM Grounding Connectors
Compression Method Grounding Connectors Save 50-75% In Time and Labor Costs
F
Blackburn (R)
This installation method results in a long lasting low installed cost connection. You can install it and forget it. Before compression, typical cable connector cross section of cable and connector consists of about 75% metal and 25% air. After Thomas & Betts method compression, the cross section shows 100% metal with virtually no air spaces.
* Eliminates exothermic welding. * Reduces labor and labor costs. * Minimize possibility of poor connections.
Thomas & Betts introduces a method of compression to replace exothermic welding and its associated disadvantages. This compression method is designed to provide quick, reliable connections for grid grounding at significantly lower installed costs since compression connectors install in less time, in any weather, and are unaffected by moisture, reducing downtime. In addition, our compression connectors for grid grounding require no special training for installation. They are made of high conductivity wrought and cast copper, and are used for connecting and tapping cross grid, loop lines, and ground rods for direct burial or concrete embedded ground grid systems. The Thomas & Betts compression system uses standard electrical connector installation tools.
* Mechanical, tensile and electromagnetic force (EMF) criteria. * Install in any weather - cut downtime. * Enhance safety. * Easy to install - no special training.
Meets all applicable specifications
Thomas & Betts grid and ground rod connectors satisfy the requirements of NEC 250-50 for connecting to the Grounding Electrode System. They also meet the requirements of U.L. Std. 467, U.L. Std. 486 CSA Std. C22.2 No. 41 and CSA Std. C22.2 No. 65 being acceptable as grounding and bonding equipment suitable for direct burial. Thomas & Betts grid and ground rod connectors also satisfy the recommended practice for the selection of grounding connector joints described in IEEE 837 standard for qualifying permanent connections used in substation grounding. The connectors conform to the following IEEE Standard 837 requirements: * 350C current cycling * Freeze-thaw test * Accelerated aging - Nitric acid/salt spray.
Reliable installations through compression connections
The Thomas & Betts method, utilizing compression tools with matching dies, forms the connector and conductor into a solid, homogeneous mass to provide an optimum electrical bond between connector and conductor. The dies are designed to produce a circumferential, hex-shaped compression rather than a simple indent. The circumferential compression creates a large area of high pressure contact between cable and connector which, in turn, assures high conductivity, low resistance, and high pullout values exceeding all industry requirements.

Thomas & Betts offers its complete line of grid-ground compression connectors. Our EZ GroundTM connectors are designed for direct burial and offer a safe, efficient alternative to exothermic welding products. Grid ground installations do not require explosive charges, and can be installed in various climate conditions. These range taking products will reduce the number of connectors and dies needed for your installation. Thomas & Betts E-Z Ground products meet all applicable standards (IEEE837, UL467, CSA 22.2). Connectors are pre-filled with oxide inhibitors and sealed.

telecom applications -- cellular, PCS and others. It provides a continuous ground to the copper bus bar making it ideal for hut and tower applications. The design allows for installation in virtually any position horizontal or vertical, and it is suitable for inside and outside plant use. Installation can be completed using any T&B compression tool that accepts U-shaped die sets and is rated 12 ton or higher. Made from pure wrought copper and pre-filled with oxide inhibitor, the EZ-Ground Bus Bar Connector has proven performance and quality.
Features and Benefits
* Fast and easy installation * Superior low-resistance, high-conductivity connections * Uses conventional compression tools * Produces a permanent connection with any combination of copper from #6 to #2 solid or stranded copper conductor, to a b" copper bus bar * UL and CSA certified
The unique patent pending design of Thomas & Betts new EZ-Ground Bus Bar Connector cuts your installation time in half, with results that are superior to conventional connectors. Installation can be completed in less than two minutes with one easy crimp! The connector attaches directly to the bus, saving the labor-intensive process of drilling and tapping. The unique jaw interface of the EZGround Bus Bar Connector grips the copper bus, resulting in a low-resistance, high-conductivity connection.

EZ GroundTM Compression Connectors
SnapTapTM Connector
Designed for bonding and grounding applications using copper, steel strand and ground rod, this unique connector can be easily installed using channel locks or pliers. It is a "snap" to assemble--no special tools are required. Made from highstrength aluminum alloy with tin plating, the connector has excellent electrical and mechanical characteristics. An electrically superior pressure fit connection is achieved in seconds without expensive tooling. The connector is also easy to disassemble requiring only a flat-head screwdriver to release the connected body. The one-piece design keeps parts together minimizing loss of components prior to assembly. Simply separate the pieces and snap them in place for the installation. There is an audible "snap" indicating the connection is complete and that you have a proper installation. Tested according to UL467, these connectors exceed performance requirements.

General Usage Instructions
Bend back and forth to separate
SEPARATION POINT
Separate No special tools required. Use ordinary parallel jaw pliers to separate the connector into two parts. Hold one side of connector with pliers and bend opposite side back and forth until parts separate. (see fig. 1) Caution: Be careful not to pinch fingers or thumb when separating parts. Keep fingers out of bend path when bending part against plier jaws.

ends with a wire brush or emery cloth if necessary. 2. Place each conductor into the grooves in BODY piece. Press conductors with pliers to align and seat into grooves. (see fig. 2) 3. Hold the conductors and BODY piece until it stops. Use parallel jaw pliers and grip the SNAP and BODY pieces as shown. (see fig. 3). Apply pressure until connector "snaps" into place. Visually inspect snap to verify full insertion. The connection is now complete. (see fig. 4) Removal The connector can be disassembled using a flat-head screwdriver to pry the SNAP piece from BODY piece.

Service Post Connectors
Application The Blackburn line of Service Post Connectors are designed for applications including steel structure, fence post or transformer grounding involving one or two cables. Service Posts can also be used to tap one or two cables from bus bar. Construction & Ratings Bolts used in the Service Post are machined from high conductivity bronze alloy while the nuts are coldformed from high strengh, corrosion resistant copper alloy. Pressure bars are copper through 4/0 size, while copper alloy is used for 350 kcmil size and above. Bolts and nuts are of the traditional Blackburn hex design for easy installation. Service Post Connectors are available in sizes accommodating AWG copper conductor ranges of #12 _ 500 kcmil stranded (4 mm2 - 240 mm2) and #12#2 solid (4 mm2 - 35 mm2). Both short and long stud versions are available. The line includes single conductor and double conductor connectors.
