Panduit EV14-38RB-Q StrongHold 16-14 AWG Ring Terminal

Panduit EV14-38RB-Q StrongHold™ Ring Terminal

The Panduit EV14-38RB-Q is a vinyl-insulated ring terminal engineered for 16-14 AWG wire and 3/8-inch stud applications in commercial power distribution, battery installations, and grounding systems. Part of Panduit's StrongHold™ contractor-grade line, this terminal delivers code-compliant terminations for low-voltage DC power, UPS battery strings, and equipment grounding in security, access control, and datacenter deployments. Tin-plated copper barrel and tongue ensure long-term conductivity in high-vibration and corrosive environments. UL 587 H Listed and CSA Certified for installations requiring agency approval. Ships 25 terminals per package.

Key Features

• 16-14 AWG wire range with 3/8-inch stud size — fits standard battery lugs, distribution blocks, and grounding bars
• Tin-plated copper construction — resists corrosion, maintains low contact resistance over decades of service
• Vinyl insulation barrel — color-coded blue for 16-14 AWG, provides strain relief and 600V dielectric strength
• UL 587 H Listed (E52164) and CSA Certified (LR31213) — meets NEC and CEC requirements for Listed terminations
• Compatible with Panduit CT-series crimp tools — factory-specified dies ensure pull-out strength and gas-tight crimps

Commercial integrators installing access control panels, surveillance NVRs, and power-over-Ethernet systems rely on ring terminals to land DC power and grounding conductors at distribution blocks, battery terminals, and chassis ground points. The EV14-38RB-Q addresses three common termination challenges: wire gauge compatibility across mixed-gauge power runs, stud size matching to OEM battery lugs and grounding bars, and code-mandated Listed terminations for inspected installations. The 3/8-inch stud bore fits industry-standard battery posts, UPS terminal blocks, and rack PDU grounding studs without shimming or oversized washers. Tin-plated finish prevents galvanic corrosion when mating with brass, bronze, or tin-plated studs in damp or HVAC-conditioned spaces.

Panduit's vinyl insulation barrel is crimped onto the wire insulation, not the conductor — this provides strain relief that prevents fatigue cracking at the crimp interface during installation torque and long-term thermal cycling. The blue color coding follows industry convention for 16-14 AWG terminals, reducing mis-application errors during high-volume rack builds. Barrel length accommodates stripped conductor lengths up to 0.38 inches, allowing compatibility with automated wire strippers set to standard 3/8-inch strip lengths. Tongue thickness is 0.032 inches, thin enough to stack multiple terminals on a single stud without exceeding NEC-allowed engagement depth, yet thick enough to resist bending during torque application. Tongue hole is punched, not drilled, with chamfered edges that prevent screw thread damage during installation.

The EV14-38RB-Q is designed for installation with Panduit's CT-series ratcheting crimp tools, which apply calibrated crimping force to create gas-tight mechanical bonds that exceed UL's 25-pound pull-out requirement for 16 AWG and 35-pound requirement for 14 AWG. Proper crimping compresses the tin-plated barrel into the copper strands, cold-welding the interface and eliminating the oxide layer that causes high-resistance terminations in aluminum or non-plated terminals. Installers working with non-Panduit crimp tools should verify compatibility with vinyl-insulated terminals and confirm that die geometry matches the hex crimp profile specified in Panduit's installation instructions.

Typical applications include 12VDC or 24VDC power distribution from access control power supplies to door strikes and card readers, battery string terminations in UPS and alarm backup systems, equipment grounding jumpers from rack-mount gear to ground bars, and DC negative returns in centralized power architectures. The 16-14 AWG range covers the majority of low-voltage branch circuit wiring — 16 AWG for runs under 50 feet at 5 amps or less, 14 AWG for longer drops or loads approaching 10 amps. Integrators provisioning standby battery systems appreciate the vibration resistance of crimped ring terminals compared to solder lugs, which can fracture under repeated thermal expansion and physical shock. Datacenter installers grounding server racks and cable trays rely on tin-plated ring terminals to maintain bond continuity in high-density environments where copper oxidation would degrade fault-clearing performance.

This product ships 25 terminals per package, with master cartons containing 10,000 pieces for high-volume contractors provisioning multi-building campuses or managing MRO inventory. The 25-pack size suits small to mid-scale projects — a typical 16-door access control installation with centralized power requires approximately 32 ring terminals (2 per door at power supply, 2 per battery string). Bulk carton pricing is available for integrators standardizing on Panduit StrongHold terminals across recurring service contracts or new-construction projects. UL Listing and CSA Certification satisfy AHJ requirements in jurisdictions mandating agency-approved terminations for low-voltage power wiring, including California Title 24 energy-monitoring circuits and NFPA 72 fire alarm notification appliance circuits that share raceways with security system wiring.
