Burndy TN10516 INSULUG™ Nylon Ring Terminal, 12-10 AWG, 5/16" Stud, 100-Pack

The Burndy TN10516 is a nylon-insulated ring terminal engineered for secure, dependable wire terminations on 12-10 AWG conductors. Sold under Burndy's INSULUG™ trade name, this terminal is built with a 1-piece copper barrel that provides a solid, low-resistance electrical path, along with an integrated insulation grip and wire strain relief that protect the crimped connection and help prevent conductor fatigue. The terminal features a 5/16" stud hole for compatibility with common terminal blocks, lugs, and mounting hardware. Each unit ships in a 100-pack, making it a practical stocking item for electrical contractors, panel builders, and MRO supply rooms that need a reliable, ready-to-use terminal on hand for routine wiring and repair work.

Key Features

  • Wire Range: Accepts 12-10 AWG conductors, covering common branch-circuit and control wire sizes.
  • Stud Size: 5/16" stud hole for straightforward compatibility with standard terminal hardware and lugs.
  • Copper Barrel Construction: 1-piece copper barrel delivers a solid, continuous electrical path for a dependable crimped termination.
  • Nylon Insulation Grip: Integrated nylon insulation grip shields the crimp area and adds resistance to abrasion and flex.
  • Wire Strain Relief: Built-in strain relief at the barrel helps reduce conductor fatigue and resist pull-out at the connection point.
  • INSULUG™ Series: Manufactured under Burndy's INSULUG™ trade name for insulated terminal connectors.
  • Bulk Pack: Supplied 100 to a box, keeping panel shops, service trucks, and production lines stocked with a consistent terminal.

Burndy TN10516 – Frequently Asked Questions

1) Will the Burndy TN10516 ring terminal work on 12 AWG and 10 AWG wire?
Yes. The TN10516 INSULUG ring terminal is rated for 12-10 AWG conductors, which covers the usual branch-circuit and control wire sizes in panel and motor-control work. Don't use it on 14 AWG or smaller - the barrel is sized for the 12-10 range and a smaller conductor won't crimp reliably.
2) Is this a ring terminal or a fork/spade terminal?
It's a closed ring (ring tongue) terminal. The tongue is a full closed circle, so the connection cannot slip off the stud if the nut backs off slightly - which is why ring terminals are preferred on vibrating equipment and motor connections. A fork terminal is the one you'd choose if you need to remove the wire without fully backing the nut off.
3) What is the barrel made of, and does it matter for aluminum wire?
The TN10516 uses a 1-piece copper barrel, so it's intended for copper conductors. Copper-only terminals should not be used on aluminum wire - that requires a connector marked AL or AL/CU with the appropriate inhibitor compound.
4) Does the nylon insulation on this Burndy terminal grip the wire jacket, or just cover the crimp?
Both. The nylon sleeve covers the crimp area and extends back as an insulation grip with built-in strain relief at the barrel, so the crimp tool captures the conductor and the wire insulation together. That reduces conductor fatigue where the wire flexes and resists pull-out at the termination - useful in control panels and harnesses where wiring gets moved during service.
5) Do I need a special crimper for nylon-insulated ring terminals?
Yes - insulated terminals are crimped with an insulated-terminal die (the color- or size-coded nest for the 12-10 AWG range), not a bare-lug indent die. A bare-metal die will split the nylon sleeve and defeat the insulation grip. The terminal itself is supplied ready to crimp; no separate sleeve or heat shrink is included or required.
6) How many terminals come in a box of Burndy TN10516?
They ship 100 to a box. That's a stocking quantity rather than a job-count pack, which is what panel shops, service trucks and MRO storerooms usually want for a terminal they use every week.
7) What is Burndy INSULUG?
INSULUG is Burndy's trade name for its line of insulated terminal connectors; the TN10516 is the 12-10 AWG, 5/16 inch stud ring terminal in that family. If a drawing or a purchasing spec calls out an INSULUG terminal, the part number to match is what identifies the exact wire range and stud size - here, TN10516.
