Panduit EV10-10FNB-Q StrongHold Insulated Vinyl Fork Terminal

Overview

The Panduit EV10-10FNB-Q is a narrow-barrel, vinyl-insulated fork (spade) terminal from the StrongHold™ line, designed for reliable wire-to-stud or wire-to-lug-bar terminations in control panels, junction boxes, and security system wiring infrastructures. It handles 12–10 AWG conductors and accepts a #10 screw, making it the go-to choice when panel real estate is tight and you need a mechanically secure, code-compliant ring-free termination that can be loosened without fully removing the screw. Sold in packs of 25 (carton quantity 10,000), the EV10-10FNB-Q is practical for both single-panel installs and larger project pulls.

Key Features

• 12–10 AWG Wire Range: Accommodates the most common control and power wire gauges used in access control panels, alarm panels, and low-voltage distribution — one terminal fits both 12 AWG home-run power feeds and 10 AWG branch circuits without stocking two SKUs.
• Narrow 0.35 in (8.9 mm) Barrel Width: The slim profile means you can place multiple terminals side-by-side on a terminal block or bus bar without the barrel overlap that causes torque-out failures. At 1 inch overall length, it also fits shallow enclosures where full-size spade terminals foul covers.
• Vinyl Insulation: The PVC sleeve provides a degree of incidental contact protection during and after termination — useful in crowded panels where bare copper shanks on adjacent terminals are a short-circuit risk. It also gives you a color-coded visual cue once you adopt a consistent wire-gauge color scheme.
• #10 Screw Size: Matches the stud hardware on the vast majority of commercial terminal strips, ground buses, and equipment grounding points used across building security and structured wiring installations. No adapter or upsizing needed.
• Tin-Plated (Verzinkt) Copper: Tin plating resists oxidation at the contact interface. In panel environments where connections may sit undisturbed for years, this matters — an oxidized copper-to-copper joint climbs in resistance over time and introduces voltage drop that upstream voltage monitors can miss until a device browns out.
• UL Listed 587H E52164 / CSA Certified LR31214: Both listings are required by most AHJs for terminations inside listed panels and enclosures. Using listed terminals keeps the installation in compliance and makes inspection straightforward — the inspector can read the listing off the terminal rather than requiring you to produce a cut sheet on-site.
• StrongHold™ Sub-Brand: Panduit's StrongHold line is purpose-built for the mechanical demands of commercial wiring — consistent crimp barrel geometry, controlled insulation thickness, and dimensional tolerances that matter when you're running a KST2000A (or equivalent) ratchet crimper. The terminal is sized for use with the KST2000A crimper (note: not sold by Panduit directly).
• Pack of 25, Carton of 10,000: The 25-pack MOQ keeps small installs lean while the 10,000-unit carton quantity means consistent per-unit pricing at volume — relevant for contractors buying for a multi-building rollout versus a single head-end.

Integration & Compatibility

The EV10-10FNB-Q (often searched as EV10 10FNB Q) is a direct competitor to the FV10-10Q from other terminal manufacturers — dimensionally equivalent and interchangeable in most applications. It terminates into any #10 threaded stud, screw terminal, or bus bar used in standard North American low-voltage and power-distribution panel builds. The recommended crimper is the KST2000A ratchet hand tool; using a non-ratchet or undersized crimper risks a partial crimp that passes a pull-test initially but loosens under vibration or thermal cycling. For larger wire bundles in high-density panels, pair with Panduit wire management products to keep terminated harnesses organized before and after the crimp. Consider browsing the full Panduit catalog for compatible labeling, duct, and termination hardware across the same installation.

For projects specifying wire termination accessories by listing type, both the UL 587H and CSA LR31214 listings are pre-verified for this SKU — no field-level lookup needed. If the application requires a ring terminal for captive studs (where the screw must be fully removed for service), a ring terminal variant in the same StrongHold series would be the appropriate swap. Consult a complete electrical accessories selection to match terminal style to enclosure hardware.

Frequently Asked Questions

Q: What wire gauge range does the EV10-10FNB-Q support?

A: The EV10-10FNB-Q accepts 12–10 AWG conductors. It will not crimp reliably on 14 AWG or smaller — use a terminal rated for that gauge range instead.

Q: What screw size does this fork terminal fit?

A: It is designed for a #10 screw. This matches the majority of commercial terminal strips and ground buses used in North American panel installations.

Q: Is the EV10-10FNB-Q UL listed?

A: Yes. It carries UL Listing 587H under file E52164 and CSA Certification under LR31214. Both listings are verified for this SKU.

Q: How many terminals come in a package, and what is the carton quantity?

A: Each package contains 25 terminals. Full cartons contain 10,000 units, suitable for high-volume project procurement.

Q: What crimper is recommended for the EV10-10FNB-Q?

A: Panduit specifies the KST2000A ratchet crimper for this terminal. Note that the KST2000A is not sold by Panduit directly; source it separately. Using a non-ratchet or improperly sized crimper risks an incomplete crimp.

Q: What is the overall size of this terminal?

A: The EV10-10FNB-Q measures 1 inch in overall length and 0.35 inches (8.9 mm) in overall width — a narrow-barrel profile suitable for dense terminal arrangements.

Karl Wilson

The EV10-10FNB-Q is the terminal I specify for any 12–10 AWG run that needs to land on a #10 stud in a panel where space is genuinely constrained. The 8.9 mm barrel width is the detail that separates it from generic spades — I've seen wider terminals cause adjacent-terminal contact in 12-gang ground bars, which fails inspection and requires a full re-termination on a live panel. The narrow StrongHold barrel avoids that problem by design.

Technical Highlights:

• Barrel Width 8.9 mm: Narrow enough to mount side-by-side on standard North American terminal strips without mechanical interference — important when you're landing six or more conductors on a single bus bar.
• UL 587H E52164 / CSA LR31214: Both listings are on the terminal itself, not just the product line — this speeds AHJ inspections and keeps your panel documentation clean without needing to pull a sub-assembly cert.
• Tin-Plated Contact Surface: Resists galvanic oxidation over multi-year service intervals, which matters in sealed or infrequently serviced enclosures where you can't inspect terminations annually.

Deployment Considerations:

• Pair only with the KST2000A ratchet crimper (not a plain plier crimper) — the ratchet mechanism ensures full crimp cycle completion, which is the difference between a connection that lasts 20 years and one that fails a vibration test after 18 months.
• This is a fork (spade) terminal, not a ring terminal — the screw does not need to be fully removed for installation or service, which speeds panel build time, but it also means the conductor can back out if the screw is insufficiently torqued. Follow the screw torque spec for your terminal block to prevent loosening under thermal cycling.

For security system integrators building access control or intrusion panels with high-density ground and power distribution requirements, the EV10-10FNB-Q is the right call when every millimeter of bus bar clearance counts and dual UL/CSA compliance is non-negotiable for the AHJ.
