Panduit EV10-10LFB-Q Insulated Vinyl Locking Fork Terminal
The Panduit EV10-10LFB-Q is a StrongHold™ vinyl-insulated locking fork terminal rated for 12–10 AWG conductors and #10 screw connections. At 1.04 inches overall length and 0.34 inches (8.6 mm) wide, it fits standard terminal strip and panel-mount applications where a secure, vibration-resistant fork termination is required. Sold in packages of 25 with a carton quantity of 250, the EV10-10LFB-Q is a practical buy for panel builders and field installers who stock terminals by the box.
Key Features
- Locking fork design: The locking tab prevents the terminal from backing off the screw under vibration — important in enclosures mounted near HVAC equipment, generators, or industrial machinery where conventional open-fork terminals can walk off the stud.
- 12–10 AWG wire range: Covers the most common control-wiring gauges in security panels, access control enclosures, and low-voltage power distribution — one part number handles both 12 AWG home-run conductors and 10 AWG branch feeds.
- #10 screw size: Matches standard terminal blocks, bus bars, and ground lugs spec'd for #10 hardware, so you are not sourcing a separate terminal size for mixed-gauge homerun panels.
- Vinyl insulation, UL587-H flammability rating: The UL587-H rating confirms the insulation resists flame propagation — relevant when terminations land inside listed enclosures where UL ratings on every component contribute to the panel's overall listing.
- Tin (verzinkt) plating: Electrotin plating resists oxidation at the contact interface, maintaining low-resistance connections over the service life of the termination without requiring anti-oxidant compound on most copper conductors.
- UL Listed and CSA Certified: UL listing E52164 (UL587H) and CSA certification LR31215 satisfy inspection requirements on commercial and industrial projects where AHJ sign-off requires listed components throughout the panel.
- Compatible crimp tools: Designed for use with Panduit CT-100A, CT-600-A (CT-550CH), CT-1550, CT-1551, and CT-2500 (CT-2550CH) crimpers — if you are already running Panduit tooling on the job, the EV10-10LFB-Q drops straight in without a tooling change.
- Package quantity of 25, carton of 250: The 25-piece pack suits smaller panel builds or top-off orders; the 250-piece carton supports high-volume rough-in work without per-piece overbuying.
Integration and Compatibility
The EV10-10LFB-Q (often searched as EV10 10LFB Q) is a direct cross to competitor part numbers LFV1010Q, TP10-10LF, and TV10-10LF-XV, making it a drop-in replacement in BOMs that specify those terminals. The #10 screw interface aligns with the majority of wire termination hardware used in Panduit panel assemblies and third-party terminal blocks. For panel builders sourcing a full terminal and connector kit, this terminal pairs logically with Panduit's insulated butt connectors and ring terminals from the same StrongHold™ line to maintain consistent insulation ratings and crimp-tool compatibility across the build.

Frequently Asked Questions
Q: What wire gauge range does the EV10-10LFB-Q accept?
A: The EV10-10LFB-Q is rated for 12–10 AWG conductors.
Q: What screw size is this terminal designed for?
A: It is designed for #10 screw connections.
Q: Which crimp tools are compatible with the EV10-10LFB-Q?
A: Panduit specifies the CT-100A, CT-600-A (CT-550CH), CT-1550, CT-1551, and CT-2500 (CT-2550CH) crimpers for this terminal.
Q: How many terminals come in a package?
A: Each package contains 25 terminals. The full carton quantity is 250 pieces.
Q: Is the EV10-10LFB-Q UL listed?
A: Yes. It carries UL listing E52164 under UL587H and CSA certification LR31215.
Q: What competitor part numbers does the EV10-10LFB-Q cross-reference?
A: Panduit lists LFV1010Q, TP10-10LF, and TV10-10LF-XV as cross-reference part numbers.
The EV10-10LFB-Q is one of those terminals that earns its place on a BOM by solving a specific mechanical problem: keeping a fork terminal seated under vibration. The locking tab geometry on this StrongHold™ part physically captures the screw head, so the terminal stays put in applications where a standard open-fork would eventually back off — generator transfer switch panels, rooftop equipment enclosures, and anything mounted near rotating machinery are the scenarios where this distinction matters in practice.
Technical Highlights:
- 12–10 AWG range: Covers both typical 12 AWG control conductors and heavier 10 AWG branch circuits with a single SKU — reduces the number of terminal part numbers you need to stock for a mixed-gauge panel build.
- UL587H / CSA LR31215 dual listing: Both the UL (E52164) and CSA listings are present, which satisfies AHJ requirements on commercial projects in the US and Canada without sourcing two different terminal types for cross-border jobs.
- Tin-plated copper barrel: Electrotin finish resists oxidation at the crimp interface — relevant on long-term installations where connection resistance creeping upward over years translates to voltage drop and potential nuisance faults at sensitive control inputs.
Deployment Considerations:
- Verify your crimper is one of the five Panduit-specified tools (CT-100A, CT-600-A, CT-1550, CT-1551, CT-2500) before ordering — an incorrect crimp die will compromise the barrel and negate the locking tab's mechanical advantage.
- At 0.34 inches (8.6 mm) wide and 1.04 inches overall length, confirm terminal strip spacing accommodates the width when landing multiple conductors on adjacent positions in high-density panels.
The EV10-10LFB-Q is the right call for security and low-voltage panel builds where inspectors require fully listed termination hardware and the installation environment introduces enough vibration to make a locking-style fork worth specifying over a standard open-fork terminal.
