6 4Connectors & Grounding Blackburn Grounding Systems Overview Blackburn EZGround Compression Connectors represent a low cost, code-approved alternative to welded ground grid connections. EZGround Connectors can be safely installed in half the time, with fewer components, and in all weather conditions. The range-taking capability of each EZGround series connector translates to fewer parts needed to complete the ground grid. EZGround Compression Connectors are installed using the T&B Method, which produces an easily inspectable die embossment on the connector indicating that the proper tool has been used and successful crimp has been made. EZGround carries the T&B Method mark of approval and represents the connection of choice for faster, simpler and safer ground grid system installations. Meets all applicable specifications Thomas & Betts grid and ground rod connectors satisfy the requirements of NEC Article 20 for connecting to the Grounding Electrode System. They also meet the requirements of UL Std. 467, UL Std. 486, CSA Std. C22.2 No. 4 and CSA Std. C22.2 No. 6 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 the IEEE 87 standard for qualifying permanent connections used in substation grounding. The connectors conform to the following IEEE Standard 87 requirements: 0 C current cycling Freeze-thaw test Accelerated aging nitric acid/salt spray Mechanical, tensile and electromagnetic force (EMF) criteria NEC and National Electrical Code are registered trademarks of the National Fire Protection Association, Inc. 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, ensures high conductivity, low resistance and high pull-out values exceeding all industry requirements. 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 7% metal and 2% air. After Thomas & Betts method compression, the cross section shows 00% metal with virtually no air spaces. Mobile Application Vehicle Before Compression Tel: After Compression

7 Overview The EZGround System Thomas & Betts offers its complete line of grid-ground compression connectors. Our EZGround 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. 2 4 C-Taps Figure 8 Connector Steel Grounding Stud TBG Series Figure 6 8 Connectors Lug Splice/Two-Way Connector Grounding Plate Pigtail Connectors Thomas & Betts EZGround products meet all applicable standards (IEEE 87, UL 467, CSA 22.2).

Snap piece Pivot groove FIG. 4 Connectors & Grounding Blackburn Grounding Systems General Usage Instructions 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. ). Caution: Be careful not to pinch fingers or thumb when separating parts. Keep fingers out of bend path when bending part against plier jaws. Installation. Strip the insulation from each de-energized conductor. Be careful not to nick the conductor. Clean the conductor 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).. Hold the conductors and BODY piece until it stops. Use parallel jaw pliers and grip the SNAP and BODY pieces as shown (see Fig. ). Apply pressure until connector snaps into place. Visually inspect snap to verify full insertion.
