Panduit 6 AWG Ring Terminal

The Panduit P6-56R-E is a bare copper ring terminal designed for 6 AWG conductors. It suits electrical and industrial wiring tasks that require a crimped connection to a 5/16 inch stud. The terminal accepts wire sizes from 6 AWG minimum to 6 AWG maximum. It is rated for up to 2,000 V and operates at temperatures up to 302 degrees F.

Voltage and crimp limits

The terminal carries a maximum voltage rating of 2,000 V. It is built for a single wire gauge, so it cannot accommodate smaller or larger conductors. Termination is crimp only, requiring the correct tooling for a secure joint. Standards met include CSA C 22.2 No. 65, UL 486A and UL 486B. The UL 94 flammability rating is not applicable.

Bare copper construction

The contact material is copper with a tin finish. Insulation coverage is none and insulation material is none, so the barrel is exposed. Barrel inside diameter is 0.23 in, barrel length is 0.51 in and barrel outside diameter is 0.23 in. Tongue width measures 0.62 in to fit the specified stud. The bare design means installers must provide their own insulation or clearance.

Highlights

  • 5/16 in stud size matches common terminal blocks
  • 2000 V rating handles high-voltage applications
  • Tin-plated copper contact resists corrosion and ensures conductivity
  • Crimp termination creates reliable, vibration-resistant joints

Questions about this item

Should I choose the 6 AWG version or a different wire size?

This terminal is built for 6 AWG only — both minimum and maximum wire size are 6 AWG — so select it when your conductor is exactly that gauge.

What does the 2,000 V rating mean when the terminal is installed in a real circuit?

It indicates the maximum voltage the crimped connection can withstand under the UL 486A and UL 486B standards, provided the barrel is correctly crimped to a 6 AWG copper conductor.

Which standards govern the crimp interface and what do they limit in practice?

The crimp interface follows UL 486A, UL 486B and CSA C 22.2 No. 65, which together cap the maximum voltage at 2,000 V and the operating temperature at 302 °F for a properly crimped 6 AWG copper wire.
