How to Install the LINK-C Deadbreak Cam Link Operable Connector System

This guide provides step-by-step instructions for installing the LINK-C 600 amp deadbreak cam link operable connector system, including mounting the stand-off plug, installing the bushing extender and elbow, and connecting the link to ensure a fully shielded and submersible connection.

Estimated time: 2h

Tools needed:

Hot stick, Torque wrench, 600ATM Operating Tool, Wire strippers, Welding equipment (if studs are not pre-welded), Suitable tool for 1 inch hex

Supplies needed:

ELASTIMOLD supplied lubricant, 3/8-16 hex nuts (6), Lockwashers (3), 3/8-16 x 2 inch studs (3, if welding), #14 AWG or #12 AWG solid copper wire, Appropriate grounding connector, Hardware supplied with alignment bracket, 600 amp elbow, Desired 200 amp mating product

  1. Prepare for Installation and Ensure Safety

    DANGER: Before beginning, ensure all apparatus is de-energized. Inspect all package contents for completeness and damage, and verify component compatibility and proper fit with the cable and mating products. Have all required tools readily available and maintain a clean work area throughout the procedure. This product should only be installed by competent personnel trained in good safety practices involving high voltage electrical equipment.

  2. Install the 600 Amp Elbow onto the Cable

    Install the 600 amp elbow onto the cable according to the specific installation instructions provided with the elbow. Ensure the elbow is positioned to align correctly with the stand-off plug.

  3. Mount the Stand-Off Plug

    If not already present, weld three 3/8-16 x 2 inch studs to the equipment faceplate according to the specified dimensions. Install three hex nuts onto the studs to support the stand-off plug, ensuring it aligns with the apparatus bushing. Place the stand-off plug over the studs, resting on the nuts or optional spacers. Secure the stand-off plug by installing a lockwasher and hex nut on each stud, then tighten all three hex nuts to 12 foot-lbs torque. Verify that the top surfaces of the bushing and stand-off plug are in-line, adjusting the nuts as needed.

  4. Install the Bushing Extender and Elbow

    Clean and thoroughly lubricate the apparatus bushing and both interfaces of the 600 amp bushing extender with ELASTIMOLD supplied lubricant. Install the bushing extender onto the apparatus bushing. Insert the 600ATM into the retainer contact, engage its internal hex broach, and thread the retainer contact into the apparatus bushing using a suitable tool on the 1 inch hex portion of the 600ATM. Torque to 50-60 ft-lbs. Next, clean and lubricate the epoxy standoff plug and both interfaces of the 600 amp elbow with ELASTIMOLD lubricant. Install the elbow onto the epoxy standoff plug. Insert the 600AMT into the retainer contact, engage its internal hex broach, and thread the retainer contact into the epoxy standoff plug through the compression lug hole. Torque to 50-60 ft-lbs.

  5. Install the Alignment Bracket

    Remove the bushing extender clamp and elbow clamp from the alignment bracket. Position the alignment bracket on the bushing extender, measuring 2.5 inches (63.5mm) from the grounding eye. Assemble the bushing extender clamp to the alignment bracket using the supplied hardware, torquing by alternating sides until the clamp tabs are flush and tight on both sides.

  6. Secure the Elbow in the Alignment Bracket

    Carefully position the elbow within the alignment bracket, ensuring the elbow cuff is lined up evenly with the bushing extender cuff. Assemble the elbow clamp to the alignment bracket using the supplied hardware. Torque by alternating sides until the clamp tabs are flush and tight on both sides. Ensure the elbow clamp notch faces the cable entrance of the elbow.

  7. Install the LINK-C Connector

    Clean and thoroughly lubricate both 600 ampere interfaces of the LINK-C connector with ELASTIMOLD supplied lubricant. Align the LINK-C connector so it is perpendicular to the switch faceplate when inserted into the bushing extender and elbow. Insert the LINK-C connector into both the bushing extender and elbow, ensuring both lever arms are inside the alignment bracket legs. Engage the pivot pin into the slots in the alignment bracket legs. Using a hot stick on the hot stick eye, push inward and move the lever arms downward to engage the roller pin and move the LINK-C connector inward. Continue until the lever arms are perpendicular to the alignment bracket leg.

  8. Ground the System and Install Mating Products

    Ground the elbow by feeding a #14 AWG or #12 AWG solid copper wire through its grounding eye, twisting it tight, and connecting it to a common ground point. Clean and lubricate the 200 amp interface on the LINK-C connector. Ground and then install the desired mating product onto the 200 amp interface, following its specific installation instructions. Ensure the cable is also properly grounded; if using concentric neutral cable, twist the neutral wires together and connect to ground with an appropriate connector. For three-phase installations, tie all grounds from all three phases to a common ground point.
