Frequently Asked Questions
What is the Elastimold GAD used for?
The Elastimold grounding-aid device (GAD) provides a permanent, reliable, direct 600 A or 900 A, 25 kA rated ground connection in underground systems where fault currents exceed 10 kA.
When should the Elastimold GAD be used?
The Elastimold GAD should be used when available fault currents exceed 10 kA in underground systems to provide a permanent, reliable ground connection.
What current ratings does the GAD support?
The GAD provides a direct 600 A or 900 A rated ground connection. Its full copper construction is ideal for these applications.
Is the Elastimold GAD hot-stick workable?
Yes, the Elastimold GAD is designed to be hot-stick workable. The associated insulating cap with integral capacitive test point is also completely hot-stick workable.
Does the GAD include a test point?
Yes, the GAD includes an insulated cap with an integral capacitive test point. This allows easy access to check if the system is de-energized.
What types of grounding clamps are compatible with the GAD?
The GAD is available for both C and ball-stud grounding clamp types. Series GAD and GADDR are for standard C-clamp connections, while BGAD and BGADDR are for ball-stud connections.
What system classes is the GAD available for?
The Elastimold GAD is an exclusive product design available in 15 kV, 25 kV, and 35 kV system classes.
How is the Elastimold GAD installed?

What is the short circuit withstand rating of the GAD?
The Elastimold GAD has a short circuit withstand rating of up to 25 kA. It is designed for 600 A and 900 A applications with full copper construction.
What is the Elastimold GAD used for?
The Elastimold grounding-aid device (GAD) provides a permanent, reliable, direct 600 A or 900 A, 25 kA rated ground connection in underground systems where fault currents exceed 10 kA.
How to Install the K671GAD Grounding Device and K676GADDR Insulated Cap
This guide provides step-by-step instructions for installing the K671GAD Deadbreak Grounding Device and the K676GADDR Insulated Cap with Test Point, including wiring and connection procedures.
Estimated time: 45m
Tools needed:
600ATM assembly tool, Torque wrench, Hotsticks, Suitable sensing device (for voltage test, if applicable)
Supplies needed:
Lubricant (supplied with product), Copper wire (No 14AWG/2.55mm or equivalent), Silicone grease
- Perform Pre-Installation Checks and Safety Procedures
Ensure all apparatus is de-energized before beginning installation. Verify that all components are undamaged, rated correctly, and compatible with mating parts. Read all instructions thoroughly and have all required tools and supplies ready. This installation must only be performed by competent personnel trained in high voltage electrical equipment safety practices.
- Clean and Lubricate K671GAD and Elbow Interfaces
Clean and lubricate the K671GAD Grounding Connector interface and the 600Amp elbow interface using only the supplied lubricant. Do not substitute lubricants, as other types may harm the product or its mating parts.
- Install the K671GAD Grounding Connector
Insert the K671GAD Grounding Connector into the 600Amp elbow. Rotate the connector clockwise to engage the stud. Then, insert the 600ATM assembly tool into the K671GAD and, using a torque wrench, continue rotating clockwise until the connector stops. Tighten to 55-60 foot-pounds torque. Remove the 600ATM tool.
- Connect K671GAD to System Ground
Take a separate copper wire (No 14AWG/2.55mm or equivalent) and insert one end through the grounding eye on the K671GAD Grounding Connector. Twist the wire tightly, being careful not to damage the eye. Connect the free end of this grounding wire to the system ground.
- Prepare K676GADDR Insulating Cap Grounding Wire
Using a separate copper wire (No 14AWG/2.55mm or equivalent), insert one end through the grounding eye of the K676GADDR insulated cap. Form a small loop and twist tightly, ensuring no damage to the grounding eye. Connect the free end of this grounding wire to the system ground. Ensure the wire length is sufficient to reach the grounding point and wrap around the insulated cap approximately 10 times (90 inches) during assembly.
- Clean and Lubricate K676GADDR and K671GAD Interfaces
Clean and lubricate the K676GADDR insulating cap and the K671GAD interface using only the supplied lubricant. Do not substitute lubricants, as other types may harm the product or its mating parts.
- Install the K676GADDR Insulating Cap
Attach the first hotstick tool to the insulated cap's assembly/disassembly bail. Push the cap receptacle onto the K671GAD bushing interface until it stops. With a second hotstick, engage the grounding wire, establishing slight tension. While pushing with the first hotstick, rotate the cap clockwise until its threads engage with the bushing. Discontinue pushing and continue turning until resistance is felt, applying a maximum torque of 15 ft-lb. Do not overtighten. Remove the second hotstick.
