Panduit EV14-6RB-Q Insulated Vinyl Ring Terminal, 16–14 AWG, #6 Screw, 25-Pack

Overview

The Panduit EV14-6RB-Q is a StrongHold™ series insulated vinyl ring terminal designed for general-purpose wire termination in commercial and industrial environments where connection reliability under vibration matters. Rated for 16–14 AWG wire and compatible with #6 (M3.5) screw sizes, this blue-coded terminal ships in packs of 25 and is available in carton quantities of 250 — the right size for panel shops, field service kits, and structured wiring closets that need UL-listed and CSA-certified terminations without overstocking bulk reels.

At 0.92 inches overall length and 0.31 inches width, the EV14-6RB-Q fits comfortably in confined terminal blocks and junction boxes common to wire termination applications in security system installations, low-voltage panels, and equipment racks. The tinned (verzinkt) finish resists corrosion, relevant in environments with humidity or mild chemical exposure.

Key Features

• 16–14 AWG Wire Range: Handles the two most common low-voltage conductor gauges in a single SKU — useful when a panel wiring job mixes 14 AWG power feeds and 16 AWG signal runs, eliminating the need to stock two terminal part numbers.
• #6 (M3.5) Screw Compatibility: The ring tongue is sized for standard #6 hardware, the dominant screw size on terminal blocks, grounding bars, and equipment chassis in low-voltage security and access control panels. No adapter or oversizing required.
• Insulated Vinyl Construction with UL587-H Flammability Rating: The vinyl insulation sleeve carries a UL 587-H flame rating, meaning it meets a defined threshold for ignition resistance — relevant in enclosed panels where a loose conductor fault shouldn't propagate fire to adjacent wiring.
• Tinned (Verzinkt) Copper Barrel: The tin finish on the crimp barrel slows oxidation at the conductor contact surface, which matters on long-term panel installations where re-termination is disruptive. Untinned bare copper terminals can develop resistance at the crimp over time in humid environments.
• Blue Color Coding: Blue is the industry-standard insulation color for 16–14 AWG ring terminals, making it straightforward to verify wire gauge visually during inspection or field audit — reduces termination errors when multiple gauges are in use on the same panel.
• Vibration-Resistant Ring Tongue Design: The closed ring tongue stays on the screw even if the fastener loosens slightly under vibration — unlike spade/fork terminals which can back off. Appropriate for equipment in mechanical rooms, near HVAC machinery, or on mobile/transit-mounted panels.
• UL Listed (587H E52164) and CSA Certified (LR31212): Both marks are evidence of third-party testing to published standards — required by many AHJs and facilities managers for panel wiring in commercial buildings. These are traceable listing numbers, not self-declarations.
• Pack of 25, Carton of 250: The 25-piece pack unit is sized for single-panel jobs or field service bags, while the 250-piece carton suits shop stock. You're not forced to buy 1,000-piece bulk to get a reasonable per-unit cost on a modest termination run.
• Crimping Tool Compatibility: Compatible with Panduit crimp tools CT-100A, CT-200, CT-600A (CT-570CH), CT-1570, CT-2500 (CT-2570CH), CT-160, and CT-257 — if your shop already runs Panduit tooling, these terminals integrate directly without sourcing a different die set. Verify your tool model against this list before ordering if you're not already in the Panduit Panduit wiring solutions ecosystem.

Integration & Compatibility

The EV14-6RB-Q (often searched as EV14 6RB Q) is a universal ring terminal — it is not proprietary to any panel brand or control system. It works wherever a #6 or M3.5 screw accepts a ring lug and the wire gauge falls in the 16–14 AWG range. Common deployment points in security system wiring include: grounding conductors on IP camera junction boxes, power supply output terminals, access control panel field wiring, and equipment chassis bonding on network racks and enclosures.

For high-density termination work on network and power distribution panels, pairing these terminals with a Panduit ratcheting crimp tool from the compatible list above ensures consistent crimp force and avoids the cold-crimp failures that show up as intermittent connections under thermal cycling. The closed-barrel design also supports inspection — a properly crimped barrel shows a uniform indent with no conductor pullout, which a pull-test at 10–15 lbf will confirm on 14 AWG.

These terminals meet the same UL and CSA standards required for commercial low-voltage wiring in the United States and Canada, covering the bulk of North American commercial security installation work.

Frequently Asked Questions

Q: What wire gauge does the EV14-6RB-Q accept?

A: The EV14-6RB-Q is rated for 16–14 AWG conductors. It is not designed for 18 AWG or 12 AWG wire — using out-of-range gauges risks an under-crimped or over-crimped barrel and a mechanically unreliable termination.

Q: What screw size does the ring tongue fit?

A: The ring tongue is sized for #6 (M3.5) screws — the standard size on most terminal blocks, grounding bars, and equipment chassis used in low-voltage security and access control panels.

Q: Is the EV14-6RB-Q UL listed?

A: Yes. The EV14-6RB-Q carries UL listing 587H under file number E52164 and CSA certification under LR31212. Both are third-party listings traceable to published standards, not self-declarations.

Q: Which Panduit crimp tools are compatible with the EV14-6RB-Q?

A: Panduit lists the following compatible crimp tools: CT-100A, CT-200, CT-600A (CT-570CH), CT-1570, CT-2500 (CT-2570CH), CT-160, and CT-257. Verify your tool model against this list — using an incompatible die set can result in inconsistent crimp depths and connection failures.

Q: How many terminals come in a package, and is a larger quantity available?

A: Each package contains 25 terminals. A full carton contains 250 terminals (10 packs), suitable for shop stock or larger panel termination jobs.

Q: Why is the EV14-6RB-Q blue, and does color matter?

A: Blue is the industry-standard insulation color code for 16–14 AWG ring terminals. The color lets you verify gauge visually during panel inspection or field audit — useful when multiple wire gauges are in use on the same installation.

Ted Perry

The EV14-6RB-Q is a UL 587H-rated, tinned-barrel vinyl ring terminal — a detail that matters more than it sounds on long-cycle commercial panel installations. I've seen untinned crimp barrels develop measurable resistance after 5–7 years in humid mechanical rooms, showing up as voltage drop on 24VDC access control readers. The tin plating on this terminal's barrel slows that oxidation process at the crimp interface, which is the highest-resistance point in the conductor path.

Technical Highlights:

• UL 587H E52164 / CSA LR31212: Both listings are file-number traceable — when an AHJ or facilities inspector asks for documentation on panel wiring, these numbers can be looked up directly rather than relying on a vendor's word.
• Closed Ring Tongue: Stays captured on the #6 screw even if the fastener backs off under vibration — relevant in mechanical rooms and equipment closets near HVAC or elevator machinery where spade terminals would be a liability.
• 16–14 AWG Range, 25-Pack: The pack-of-25 unit covers a single panel run without committing to a 1,000-piece spool. For shops that stock by job, this is a more practical reorder unit than bulk reels.

Deployment Considerations:

• Verify your crimp tool is on the EV14-6RB-Q compatibility list (CT-100A, CT-200, CT-600A, CT-1570, CT-2500, CT-160, CT-257) before ordering. A mismatched die produces a cold crimp that passes visual inspection but fails a 10-lbf pull test.
• This terminal is blue-coded for 16–14 AWG. If your installation uses 18 AWG or 12 AWG conductors on the same panel, order the correct gauge-coded terminals separately — mixing gauges in a single terminal type is a common inspection failure point.

For commercial access control or intrusion panel wiring where an AHJ sign-off is required and the installation will live for 10+ years without re-termination, the EV14-6RB-Q's dual third-party listings and tin-plated barrel make it the lower-risk choice over unbranded alternatives at similar price points.
