How to Install the ST2GR-G Grounding Connector

This guide provides step-by-step instructions for installing the ST2GR-G grounding connector, ensuring a secure and compliant connection.

Estimated time: 30m

Tools needed:

Screwdriver, Wire strippers, Multimeter

Supplies needed:

Mounting screws, Terminal connectors, Flexible conduit

  1. Prepare the conduit

    Cut the flexible conduit with a clean, square end using a sharp hacksaw or power band saw. Ensure the cut is clean to facilitate proper installation.

  2. Assemble the grounding connector

    Remove the round shape support from the PVC coating on the gland nut. Slide the gland and nylon sealing ring onto the conduit, ensuring the open side of the lug on the ground ring is facing the gland nut.

  3. Secure the connector

    Thread the ground cone into the conduit and slide the body onto the cone. Tighten the gland nut according to the torque specifications provided in the installation guide.

  4. Connect the grounding conductor

    Install the grounding conductor in the lug and tighten the lug screw according to the torque table. Ensure all connections are secure.

  5. Verify the installation

    Use a multimeter to check for continuity and ensure that the grounding connection is properly established. Confirm that all circuits are de-energized before performing this check.
