Overview

The ABB K676GADDR 600 Series Insulating Cap is a critical safety component for medium-voltage grounding applications. Rated for 15/25 kV and 600 Amps continuous current, this EPDM rubber cap is designed to interface with ABB’s 600 Series Grounding Device (GAD) for reliable, direct grounding connections in electrical distribution systems. The cap includes a capacitive test point to verify voltage absence before grounding, ensuring operational safety during maintenance and fault conditions. Engineered to meet ANSI/IEEE Standard 386, it withstands 95 kV BIL (1.2 x 50 µs impulse) and 34 kV AC for 1 minute in the 15 kV class, with corresponding ratings of 140 kV BIL and 45 kV AC for the 25 kV class. The 25 kA symmetrical momentary rating (10 cycles) provides robust fault current handling. Constructed from durable EPDM rubber, the cap resists environmental degradation while maintaining insulation integrity. It is specifically designed for use with 600 A series elbow connectors (T-body) to ground de-energized circuits via a grounding cable, enhancing safety in daily operations.

How to Install the K671GAD Grounding Device and K676GADDR Insulated Cap

This guide provides step-by-step instructions for safely installing the K671GAD Deadbreak Grounding Device and the K676GADDR Insulated Cap with Test Point onto a 600Amp elbow, including wiring and lubrication procedures. Ensure all apparatus are de-energized before beginning.

Estimated time: 1h

Tools needed:

600ATM Assembly Tool, Torque Wrench, Hotstick (2 required), Voltage Sensing Device (for capacitive test points)

Supplies needed:

Lubricant (supplied with product), No. 14 AWG Copper Grounding Wire, Silicone Grease

  1. Prepare for Installation and Safety Check

    DANGER: All apparatus must be de-energized during installation or removal of parts. Do not touch or move energized products. Inspect all parts for damage, correct rating, and compatibility with mating parts. Read all instructions thoroughly before starting and ensure all required tools are at hand. Maintain cleanliness throughout the procedure.

  2. Install the K671GAD Grounding Connector

    Install the 600Amp elbow onto the apparatus bushing following its specific instructions; do not install an insulating plug or cap. Clean and lubricate the K671GAD Grounding Connector interface and the 600Amp elbow interface using only the supplied lubricant. Insert the K671GAD Grounding Connector into the elbow and rotate clockwise to engage the stud. Insert the 600ATM assembly tool into the K671GAD and, using a torque wrench, continue rotating clockwise until it stops. Tighten to 55-60 foot-pounds torque. Remove the 600ATM tool.

  3. Connect K671GAD to System Ground

    Using a separate No. 14 AWG (2.55mm) copper wire or equivalent, insert one end through the grounding eye on the K671GAD Grounding Connector. Twist the wire tightly, taking care not to damage the eye. Connect the free end of the grounding wire to the system ground.

  4. Prepare K676GADDR Insulating Cap Grounding Wire

    Using a separate No. 14 AWG (2.55mm) copper wire or equivalent, insert one end through the grounding eye of the insulated cap. Make a small loop and twist tightly, ensuring not to damage the grounding eye. Connect the free end of this grounding wire to the system ground. The length of this wire should be sufficient to reach the grounding point and wrap around the insulated cap approximately 10 times (90 inches) during assembly.

  5. Install the K676GADDR Insulating Cap

    Clean and lubricate the K676GADDR insulating cap and the K671GAD interface with the supplied lubricant; do not substitute. Attach the first hotstick tool to the insulated cap assembly/disassembly bail and push the receptacle onto the bushing interface until it stops. With a second hotstick, engage the grounding wire and establish slight tension, wrapping it loosely around the center of the insulated cap. While pushing with the first hotstick, rotate clockwise until the threads between the bushing and the cap engage. Discontinue pushing and continue turning until resistance is felt, applying a maximum torque of 15 ft-lb. DO NOT OVERTIGHTEN. Remove the second hotstick.
