Panduit P8-10R-Q Pan-Term Ring Terminal
The Panduit P8-10R-Q is a non-insulated ring terminal designed for terminating 8 AWG stranded copper conductors to #10 studs in power distribution, grounding, and battery interconnect applications. Part of Panduit's Pan-Term product line, this compression-style lug features internal barrel serrations that bite into the conductor for maximum tensile strength and low-resistance contact—critical for security system power supplies, UPS installations, datacenter ground bars, and access control strike connections where vibration, thermal cycling, or fault currents demand reliable terminations over decades of service.
Key Features
- 8 AWG wire capacity with #10 (M5) screw-stud compatibility for common power distribution and grounding points
- Non-insulated barrel design allows visual inspection of crimp quality and conductor seating during install
- Tin-plated copper construction resists corrosion in indoor electrical enclosures and mild industrial environments
- Internal barrel serrations provide gas-tight mechanical bond and rated pull strength per UL 486A-486B standards
- cULus Listed (E52164) and CSA Certified (LR31212) for use in electrical distribution equipment up to 600V
- Tongue dimensions 0.47 in × 1.14 in (11.9 mm × 29 mm) fit standard terminal blocks and breaker lugs
- Requires Panduit CT-1701 or CT-2600 hand crimpers with CD-2600-P8 die set for proper compression
The P8-10R-Q employs a seamless copper tube barrel with precision-formed internal teeth that displace conductor strands during crimping, creating multiple contact points and preventing strand relaxation under load. The tin electroplating (per ASTM B545) provides a solderable surface and inhibits galvanic corrosion when mated to brass or bronze terminal studs. The 0.21 in (5.3 mm) barrel inner diameter accommodates Class B stranded conductors per ASTM B8, while the tongue's 0.203 in (5.16 mm) hole diameter fits #10 screws with clearance for thermal expansion. Non-insulated construction suits applications where color-coding is unnecessary or where inspectors require visual verification of crimp depth—common in fire alarm control panels, elevator machine rooms, and utility metering cabinets subject to NFPA 70 Article 110.14 workmanship requirements.
Installers provisioning security system power typically encounter 8 AWG conductors on 15–20A branch circuits feeding PoE switch infrastructure, on DC bus bars distributing 12–48V to access panels, or on battery strings where torque specs and pull-test documentation are mandatory for UL 2572 or UL 294 listings. The P8-10R-Q's #10 stud size matches the majority of terminal blocks in Altronix, Lowell, and Suttle enclosures, as well as grounding lugs on rack PDUs and the negative bus in ELK or DSC combo boards. Its 1.14 in overall length provides working clearance in crowded j-boxes, and the 25-piece bulk pack suits service vans stocking consumables for retrofit projects. Panduit's CT-1701 ratcheting hand crimper (sold separately) applies calibrated force across six crimp points to meet the 35 lb minimum pull requirement, while the hexagonal crimp profile deters over-compression that can sever strands or crack plating.
This terminal is cULus Listed under UL 486A-486B for copper conductors in electrical equipment and CSA LR31212 for Canadian installations, satisfying inspector signoff for commercial access control, intrusion detection, and CCTV projects governed by NEC Articles 725, 760, and 800. Panduit backs the Pan-Term line with lot traceability and material certifications available on request—essential when job specifications reference NFPA 70E arc-flash studies or when integrators must document every connection in a UL 2050 central-station monitoring path.
