Panduit VS-CKP1K4/0-500 VeriSafe AVT Insulation Piercing Connection Kit
The Panduit VS-CKP1K4/0-500 is a VeriSafe™ insulation piercing connection kit engineered specifically for tapping AWG 4/0 to 500 MCM copper conductors in 1KV-rated electrical installations. If you're deploying an Absence of Voltage Tester (AVT) on large-conductor distribution equipment — switchgear, industrial panels, or MV feeder applications — this kit provides the mechanical tapping connection without stripping insulation or breaking the conductor, keeping the primary circuit intact while establishing the measurement point for the AVT.
Overview
The VS-CKP1K4/0-500 (often searched as VS CKP1K4/0 500) is part of Panduit's VeriSafe™ ecosystem, which is built around the principle of safe, repeatable absence-of-voltage verification before workers contact energized equipment. The connection kit solves a specific mechanical problem: how do you establish a reliable, code-acceptable measurement tap on a large-gauge conductor without disrupting the existing installation? The answer is insulation-piercing technology — the connector bites through the insulation jacket under controlled torque, making metal-to-metal contact with the copper conductor beneath. No insulation stripping, no conductor re-termination, no re-routing required.
Key Features
- AWG 4/0 to 500 MCM Conductor Range: this is the heavy end of the conductor spectrum — feeders and mains, not branch circuits. If you're working on service entrance equipment, main switchboards, or 480V distribution panels where conductors are in the 300–500 MCM range, this is the kit that fits. Attempting to use a smaller-gauge IPC kit on 500 MCM conductors risks poor contact integrity and is a safety violation; use the correct kit for the conductor size.
- 1KV Voltage Rating: rated for 1,000V installations, which covers the full range of low-voltage power distribution in North American commercial and industrial facilities (600V class systems, 480V three-phase, 277V single-phase). The 1KV rating provides margin above system nominal, which matters for transient overvoltage scenarios common on inductive industrial loads.
- 3-Connector Kit Per AVT Installation: each VS-CKP1K4/0-500 includes exactly 3 connectors — one per phase for a complete three-phase AVT installation. A single kit provisions one AVT point. If you're installing AVTs on multiple feeder positions or in a multi-compartment switchboard, plan your kit quantity accordingly: one kit per three-phase tap point.
- Insulation-Piercing Technology: the piercing mechanism eliminates insulation stripping, which on large-gauge conductors is time-consuming and carries risk of nicking the copper strands. The IPC design also means the connection is mechanically stable and repeatable — torque the connector to spec and the contact force is consistent, not dependent on installer technique with a stripper and lug.
- VeriSafe AVT Ecosystem Compatibility: this kit is designed specifically for use with Panduit's VeriSafe AVT product line. The competitor cross-reference TTD0810XF indicates it addresses the same application space as comparable tapping products. Verify fitment with your specific AVT model before ordering — AVT connection kits are not universally interchangeable across all VeriSafe product configurations.
- Single-Unit Package Quantity: sold individually (package quantity: 1 kit = 3 connectors). For panel or switchboard installations with multiple feeder positions, calculate total kit quantity as number of three-phase tap points required.
Integration and Compatibility
The VS-CKP1K4/0-500 is designed for integration within the Panduit VeriSafe™ AVT system, which addresses NFPA 70E absence-of-voltage verification requirements. The connection kit establishes the physical measurement interface between large-gauge power conductors and the AVT device. Application contexts include main switchboard compartments, motor control center (MCC) feeder sections, and distribution panelboard mains where conductors fall in the AWG 4/0 to 500 MCM range. The 1KV system rating aligns with 600V-class switchgear and distribution equipment standard in industrial facilities, data centers, and large commercial buildings.
Before specifying this kit, confirm the conductor material is copper — the VS-CKP1K4/0-500 is specified for copper conductors. Aluminum conductors in the same gauge range are a different application and may require different IPC hardware. Verify with Panduit's VeriSafe product documentation for aluminum conductor compatibility.

Frequently Asked Questions
Q: What conductor sizes does the VS-CKP1K4/0-500 support?
A: The VS-CKP1K4/0-500 supports AWG 4/0 to 500 MCM copper conductors. It is not intended for smaller branch-circuit conductors or aluminum conductors in this gauge range.
Q: How many connectors are included in the VS-CKP1K4/0-500 kit?
A: The kit includes 3 insulation piercing connectors, which is the correct quantity to install one Absence of Voltage Tester (AVT) on a three-phase system. One kit equals one AVT installation point.
Q: What is the voltage rating of the VS-CKP1K4/0-500?
A: The VS-CKP1K4/0-500 is rated for 1KV (1,000V) installations, making it suitable for standard North American 600V-class low-voltage power distribution systems including 480V three-phase applications.
Q: Does the VS-CKP1K4/0-500 require stripping the conductor insulation?
A: No. The insulation-piercing connector design bites through the conductor's insulation jacket to establish metal-to-metal contact with the copper conductor underneath. No insulation stripping or conductor re-termination is required.
Q: What VeriSafe system is the VS-CKP1K4/0-500 designed for?
A: This connection kit is designed for use with Panduit's VeriSafe Absence of Voltage Tester (AVT) product line. Verify compatibility with your specific AVT model before ordering, as AVT connection kits are configuration-specific.
Q: Is the VS-CKP1K4/0-500 sold as a single kit or in bulk cartons?
A: The VS-CKP1K4/0-500 has a package quantity of 1 (one kit containing 3 connectors). The carton quantity is 0, indicating it is sold individually rather than in multi-pack cartons.
The VS-CKP1K4/0-500 occupies a very specific slot in electrical safety commissioning work: it's the physical interface that makes an AVT installation feasible on conductors up to 500 MCM without a full re-termination. That 1KV rating with the AWG 4/0–500 MCM range covers the heavy feeder applications where you genuinely need absence-of-voltage confirmation before anyone opens a compartment door — main switchboards, large MCC sections, service entrance gear. This is not a product you can substitute with a general-purpose connector.
Technical Highlights:
- 1KV Voltage Rating: provides code-acceptable margin above 600V-class system nominal, covering the full low-voltage distribution range in industrial and commercial facilities including 480V three-phase equipment.
- 3-Connector Kit Configuration: the kit is sized for exactly one three-phase AVT installation — no partial kits, no waste. If your switchboard has six feeder positions requiring AVTs, you need six VS-CKP1K4/0-500 kits.
- Insulation-Piercing Mechanism: eliminates the insulation-stripping step on conductors where stripping is slow and introduces strand-nick risk. The controlled-torque piercing contact is more consistent than field-stripped lug terminations on large-gauge copper.
Deployment Considerations:
- Conductor material matters: the VS-CKP1K4/0-500 is specified for copper conductors in the 4/0–500 MCM range. Aluminum feeders in the same gauge range are a different application — confirm with Panduit VeriSafe documentation before installing on aluminum.
- This kit provisions one AVT point. For multi-feeder or multi-compartment installations, kit quantity planning is critical — arriving on-site with one kit short on a large switchboard commissioning job is an avoidable schedule problem.
For industrial facilities commissioning new switchgear or retrofitting existing distribution equipment for NFPA 70E absence-of-voltage compliance on heavy feeders, the VS-CKP1K4/0-500 is the connector kit that fits the conductor range — the 500 MCM upper limit aligns with typical 1200A–2000A main feeder sizes where AVT requirements are most common.
