Panduit EV14-8RB-L StrongHold Insulated Vinyl Ring Terminal

Overview

The Panduit EV14-8RB-L is a StrongHold™ vinyl-insulated ring terminal engineered for 16–14 AWG wire and #8 screw terminations. Whether you're wiring access control panels, security system backboxes, or low-voltage distribution points, this ring terminal delivers a mechanically sound, UL-listed connection in a compact 0.92-inch overall length. The EV14-8RB-L (often searched as EV14 8RB L) ships in 50-piece packages — sized for single-job quantities without committing to full-carton bulk.

Key Features

• 16–14 AWG Wire Range: Sized for the most common low-voltage wiring gauges in security and access control installations — 16 AWG alarm cable and 14 AWG power feeds both terminate cleanly without under- or over-crimping.
• Vinyl Insulation with UL587-H Flammability Rating: The PVC sleeve meets UL587-H flammability requirements, meaning the insulation resists flame spread — a relevant factor in enclosed panels and conduit runs where heat or arcing is a concern.
• Tinned Copper Construction (Verzinkt Finish): The tin-plated barrel resists corrosion in humid or high-condensation environments such as outdoor control enclosures and mechanical rooms, extending the service life of the termination without additional treatment.
• #8 Screw Size Compatibility: Designed specifically for #8 hardware — the most common stud size on terminal blocks, ground bars, and panel lugs in low-voltage security equipment. No adapters, no oversized ring flopping on a small stud.
• 0.92-Inch Overall Length: The compact 0.92-inch length keeps terminated wire runs tidy inside crowded panel enclosures. Paired with the 0.31-inch (7.9mm) ring width, this terminal fits standard terminal block spacing without overlap.
• UL Listed and CSA Certified: Carries UL Listing 587H E52164 and CSA Certification LR31212 — both required for commercial building and life-safety applications where inspectors verify component compliance on the panel label.
• Compatible with Panduit CT-Series Crimp Tools: Verified for use with the CT-100A, CT-200, CT-600A (CT-570CH), CT-1570, CT-2500 (CT-2570CH), CT-160, and CT-258 — if your crew already runs Panduit crimp tools, these terminals mate directly without purchasing new tooling or adjusting die settings.
• 50-Piece Package Quantity: The 50-piece pack is practical for project-level buys — enough for a mid-size access control or camera installation without over-stocking. Full cartons of 500 are available when volume justifies it.

Integration and Compatibility

The EV14-8RB-L fits into any low-voltage termination workflow that uses standard #8 ring lug connections. Common applications include ground terminations in access control panels, power supply output wiring for door hardware, camera junction box grounding, and alarm system terminal block connections. Cross-reference competitor part numbers 83-2231, RV14-8Q, TP148RBG25, and TV14-8R-XV when replacing existing stock from other manufacturers — the EV14-8RB-L is a direct functional equivalent for those part numbers in the 16–14 AWG / #8 class.

Crimp tooling compatibility is explicitly verified: the CT-100A through CT-258 range covers both handheld and bench-mount Panduit crimp tools, so mixed-tool shops don't need to audit their kit before ordering.

Frequently Asked Questions

Q: What wire gauge range does the EV14-8RB-L accept?

A: The EV14-8RB-L is rated for 16–14 AWG conductors. It is not suitable for heavier gauges such as 12 AWG or lighter gauges such as 18 AWG — use the appropriate Panduit terminal for those wire sizes.

Q: What stud or screw size does the EV14-8RB-L fit?

A: The ring is sized for #8 hardware. This covers #8 screws, #8 studs on terminal blocks, and #8 ground lugs — the most common fastener in low-voltage security and access control panels.

Q: Is the EV14-8RB-L UL Listed?

A: Yes. It carries UL Listing 587H under file number E52164, and CSA Certification under LR31212. Both are visible on the part labeling and required for commercial life-safety inspections.

Q: What crimp tools are compatible with the EV14-8RB-L?

A: Panduit verifies compatibility with the CT-100A, CT-200, CT-600A (CT-570CH), CT-1570, CT-2500 (CT-2570CH), CT-160, and CT-258 crimp tools. Using an incompatible tool risks an incomplete crimp and a failed pull-test.

Q: How many terminals are included per package?

A: Standard packages contain 50 terminals. Full cartons contain 500 terminals (10 packages).

Q: What are the cross-reference part numbers for the EV14-8RB-L?

A: The EV14-8RB-L crosses to competitor part numbers 83-2231, RV14-8Q, TP148RBG25, and TV14-8R-XV in the 16–14 AWG #8 ring terminal class.

Jerry Tildsen

The EV14-8RB-L is the terminal I stock on every security panel rough-in job — 16–14 AWG covers the majority of alarm cable and door hardware power feeds, and the #8 ring fits almost every ground bar and terminal block I encounter in commercial access control enclosures. The UL Listing (587H E52164) and CSA Certification (LR31212) mean no red-tag delays when the AHJ walks the panel.

Technical Highlights:

• UL587-H Flammability Rating: The vinyl sleeve is rated to resist flame propagation under UL587-H — relevant in enclosed backboxes where a wiring fault could otherwise allow insulation to contribute to fire spread.
• Tinned Barrel (Verzinkt): Tin plating on the copper barrel resists oxidation in the humidity swings common in outdoor and mechanical room enclosures — raw copper terminals can develop resistance at the crimp joint over time; tin plating slows that degradation significantly.
• 50-Piece Pack / 500-Piece Carton: The 50-piece package quantity is correctly sized for single-job use. Over-buying bulk 500-piece cartons of specialty ring sizes creates bin clutter; the 50-pack keeps the job kit lean.

Deployment Considerations:

• Verify your crimp tool is on the validated list (CT-100A, CT-200, CT-600A, CT-1570, CT-2500, CT-160, CT-258) before crimping — an off-list tool may not fully compress the barrel to spec, which shows up as a failed pull-test at inspection.
• The 0.92-inch overall length is compact, but confirm ring clearance in high-density terminal blocks — 7.9mm ring width is standard for #8 but can be tight if adjacent terminals are on 8mm or closer pitch.

For access control panel groundings, door strike power feeds, and camera junction box terminations running 16–14 AWG to #8 studs, the EV14-8RB-L covers the bulk of field terminations without requiring a separate terminal assortment for the most common wire-stud combinations on a commercial security project.
