Panduit EV18-10RB-L StrongHold Vinyl Insulated Ring Terminal

Overview

The Panduit EV18-10RB-L is a tin-plated copper ring terminal from the StrongHold™ product line, designed for crimp terminations on 22–18 AWG conductors at #10 stud sizes. At 0.94 inches overall length and 0.31 inches wide, it fits tight panel layouts and junction boxes without crowding adjacent lugs. If you're wiring control panels, security system enclosures, or low-voltage distribution points where screw-lug reliability matters, the EV18-10RB-L is a code-compliant, dual-listed option that takes the guesswork out of spec compliance.

Key Features

• 22–18 AWG Conductor Range: Covers the most common control-wire gauges in a single SKU — from 22 AWG signal leads up to 18 AWG power feeds. You won't need separate bins for adjacent wire sizes on the same project.
• Tin-Plated Copper Construction: Tin plating resists oxidation on the barrel contact surface, which matters on terminations that may see moisture ingress or years between inspection cycles. Copper core maintains conductivity even after repeated torque cycles on the stud.
• Vinyl Insulation, UL 587 H Flammability Rating: The vinyl sleeve meets UL 587 H flammability requirements — meaning it self-extinguishes rather than propagating flame in a panel fire scenario. That's a real specification, not just marketing language, and it satisfies NEC requirements in listed assemblies.
• #10 Stud Size: The ring bore is sized for #10 hardware, which is the workhorse stud in DIN rail terminal blocks, grounding lugs, and equipment chassis ground points. If you're mixing stud sizes in the same panel, confirm your other runs before ordering in bulk.
• UL Listed 587H E52164 and CSA Certified LR31212: Both marks are on the product, which means it's independently tested and traceable to a file number — not self-declared. Inspectors and AHJs with jurisdiction in Canada or the US will recognize both marks without additional paperwork from you.
• Compatible Crimp Tools — CT-100A, CT-600-A, CT-1550, CT-1551, CT-2500, CT-160, CT-260, CT-400: Panduit publishes the exact tool list (EV18-10RB-L often searched as EV18 10RB L). If your field kit runs one of these Panduit crimp tools, you already have the correct die set. Using an uncalibrated or non-listed tool risks cold or over-crimped barrels that pass visual inspection but fail under load — use the listed tools.
• 50-Piece Package, 500-Piece Carton: The pack-of-50 MOQ is practical for single-panel jobs or small install crews. If you're stocking a truck or filling a supply cage, the 500-piece carton keeps per-unit cost down without over-committing to a single gauge-stud combination.
• 0.94-Inch Overall Length: Compact enough to fit multi-row terminal strips without having to fold or bend leads. At 7.9 mm wide, neighboring lugs on standard 5 mm pitch terminal blocks won't physically interfere during insertion.

Integration and Compatibility

The EV18-10RB-L is listed for use with Panduit crimp tools CT-100A, CT-600-A (CT-550CH), CT-1550, CT-1551, CT-2500 (CT-2550CH), CT-160, CT-260, and CT-400. The terminal is designed for copper conductors only — do not use with aluminum wire, which requires a separate terminal series with anti-oxidant compound. The StrongHold™ line covers a range of stud sizes and AWG combinations; if your panel runs 16–14 AWG or requires a #8 or #12 stud, confirm the correct part number before ordering. Panduit's wire-termination catalog includes direct cross-references to competitor parts RV18-10Q, BA16E10, 83-2141, and TV18-10R-XV for teams transitioning from another brand's inventory.

Frequently Asked Questions

Q: What wire gauges does the EV18-10RB-L accept?

A: The EV18-10RB-L is rated for 22–18 AWG copper conductors. Do not use with aluminum wire or outside this gauge range, as the barrel crimp geometry is sized specifically for this conductor range.

Q: What stud size does the EV18-10RB-L ring bore fit?

A: The ring terminal is sized for #10 stud hardware, which is standard on DIN rail terminal blocks, chassis ground studs, and equipment grounding points.

Q: Which crimp tools are listed for use with the EV18-10RB-L?

A: Panduit specifies the CT-100A, CT-600-A (CT-550CH), CT-1550, CT-1551, CT-2500 (CT-2550CH), CT-160, CT-260, and CT-400 as listed crimp tools for this terminal. Using non-listed tools risks an improper crimp that may not be visually obvious.

Q: Is the EV18-10RB-L UL Listed and CSA Certified?

A: Yes. The EV18-10RB-L meets UL Listed 587H (file E52164) and CSA Certified LR31212 standards. Both marks are independently tested and carry traceable file numbers for inspection documentation.

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

A: The standard package contains 50 pieces. A 500-piece carton is available for higher-volume stocking needs.

Q: What is the flammability rating of the vinyl insulation?

A: The insulation carries a UL 587 H flammability rating, meaning it is tested to self-extinguish rather than propagate flame — a requirement in many listed panel assemblies under NEC.

James Everett

The EV18-10RB-L is the kind of terminal that doesn't get discussed at length on a job site — it just needs to work, hold its crimp, and pass inspection. What actually differentiates it from generic house-brand alternatives is the dual listing: UL 587H E52164 and CSA LR31212 are both independently verified file numbers, not self-declared marks. On a commercial security panel going through AHJ inspection in a jurisdiction that requires CSA compliance, that distinction matters significantly.

Technical Highlights:

• Tin-Plated Copper Barrel: Tin plating actively resists oxidation at the conductor contact point. In enclosures that see humidity cycling — outdoor pedestals, parking structure panels, unheated equipment rooms — a bare copper barrel will oxidize over time and raise contact resistance. Tin plating delays that degradation without adding cost.
• 22–18 AWG Rated Range: The 0.94-inch overall length and 7.9 mm width are matched to this conductor range. If a technician forces a 16 AWG conductor into this barrel because it's the only ring terminal on the truck, the crimp will be under-compressed and the joint will fail a pull test. Stud size and gauge range are non-negotiable here.
• UL 587 H Flammability: Self-extinguishing insulation is a code-relevant spec, not a marketing one. Listed assemblies in NEC Article 110 environments require flame-rated insulation on terminations. The H suffix confirms the vinyl passes the horizontal burn test under UL 587.

Deployment Considerations:

• Match your crimp tool to the published list (CT-100A, CT-600-A, CT-1550, CT-1551, CT-2500, CT-160, CT-260, CT-400). Cold crimps — where the tool didn't fully close — are the leading cause of ring terminal field failures and are invisible without a pull test or thermal imaging under load.
• This terminal is specified for copper conductors only. If your run includes aluminum branch circuits or aluminum-clad wire (common in older commercial buildings), you need a different terminal series with listed aluminum-compatible barrels and anti-oxidant compound.

The EV18-10RB-L is well-suited for commercial security panel builds, access control power distribution, and low-voltage control wiring in structured wiring enclosures — anywhere a #10 ground or signal stud terminates 22–18 AWG copper and you need both UL and CSA documentation for the inspection package.
