Burndy KA4C Copper 1-Hole Mechanical Lug, 1/4" Stud

The Burndy KA4C is a high copper alloy, compact 1-hole mechanical terminal engineered for dependable conductor termination in commercial, industrial, and utility electrical systems. This compact mechanical lug is built with a 1/4" stud and covers a conductor range from #14 AWG solid up through 4 AWG stranded, making it a versatile connector for a wide variety of wire gauges encountered in the field. The single-hole mounting configuration keeps the overall footprint small, allowing electricians to make secure terminations even in tightly packed panels, enclosures, and equipment grounding points. Backed by Burndy's reputation for connector reliability, the KA4C is a practical choice wherever a compact, code-compliant mechanical termination is required.

Key Features

  • 1/4" Stud Size: Sized for compatibility with standard 1/4" mounting hardware, simplifying integration into existing panels, bus bars, and grounding points.
  • High Copper Alloy Construction: Manufactured from high copper alloy material for strong electrical conductivity and long service life in demanding electrical environments.
  • Compact 1-Hole Design: The single-hole mounting configuration reduces the connector's footprint, easing installation in space-constrained panels, enclosures, and wireways.
  • Wide Conductor Range: Terminates conductors from #14 AWG solid through 4 AWG stranded, giving installers flexibility across multiple wire gauges with a single lug design.
  • Unplated Finish: Supplied with an unplated copper alloy finish for direct, low-resistance conductor contact.
  • Space-Saving Profile: The compact body helps maintain clearances inside crowded gutters, wireways, and termination compartments where room is limited.

Burndy KA4C – Frequently Asked Questions

1) What wire sizes will the Burndy KA4C mechanical lug accept?
The KA4C takes conductors from #14 AWG solid through 4 AWG stranded. That one range covers most branch circuit and equipment grounding conductors you'll hit in a panel, so a single lug part number handles several gauges on the same job instead of stocking one lug per size.
2) Is the Burndy KA4C lug copper or aluminum, and can I use it on aluminum conductor?
The body is high copper alloy, supplied unplated. It is a copper-bodied terminal for copper conductor; aluminum or dual-rated AL9CU applications call for a lug rated for aluminum instead. Unplated means bare copper alloy contact at the conductor seat.
3) Mechanical lug or compression lug for terminating a #6 ground in a panel?
A mechanical lug like the KA4C clamps the conductor with a set screw, so it installs with a hex key or driver and no crimp tool, and it can be backed off and re-terminated. A compression lug needs a matched die and crimper and is a one-shot termination. For occasional panel and grounding work in the 14 to 4 AWG range, the mechanical version is the practical pick; high-vibration or high-density production work usually goes compression.
4) What is the exact part number to order for the Burndy compact 1-hole copper lug with a 1/4 inch stud?
Order Burndy KA4C. That is the manufacturer part number for the compact one-hole high copper alloy mechanical terminal, unplated, 14-4 AWG, 1/4 inch stud.
5) Does the Burndy KA4C come with the mounting bolt and washer?
No. The KA4C is the lug only, with its conductor set screw. The 1/4 inch bolt, nut, and washers that fasten it to the stud or bus bar are supplied by the installer or come with the enclosure, so add that hardware to your material list if the panel does not already have a stud in place.
6) Will a KA4C fit in a crowded panel gutter without crowding my bending space?
That is what the single-hole configuration is for. Keeping one mounting hole instead of two shortens the tongue and keeps the overall footprint small, which is why it gets used in tight panels, enclosures, and wireways where a two-hole lug would eat the clearance.
