Burndy KPA4CTP SCRULUG™ 1-Hole Copper Mechanical Lug, 1/4" Stud

Burndy KPA4CTP SCRULUG™ 1-Hole Copper Mechanical Lug, 1/4" Stud

The Burndy KPA4CTP is a SCRULUG™ 1-Hole copper mechanical lug designed to terminate conductors ranging from 14 AWG (Sol) to 4 AWG (Str) onto a 1/4" stud. Machined from solid copper for dependable conductivity, this one-piece pressure bar lug provides a secure mechanical connection for grounding, bonding, and equipment wiring in commercial and industrial electrical systems. Because it uses a set-screw pressure bar rather than a crimp, it can be installed or removed in the field with standard hand tools, making it a practical option for panel work, service upgrades, and maintenance where a compression tool is not available.

Key Features

• 1/4" Stud: Sized to mount securely to grounding and bonding hardware, bus bars, and equipment lugs using a 1/4" stud.
• Wire Range: Accepts 14 AWG (Sol) through 4 AWG (Str) conductors, giving electricians flexibility across a range of circuit sizes on a single terminal.
• Solid Copper Construction: The copper terminal body delivers excellent electrical conductivity and long-term durability in demanding commercial and industrial installations.
• 1-Hole Configuration: A single-hole pad simplifies mounting to ground bars, bus bars, panelboards, and other equipment with a single fastener.
• One-Piece Mechanical Design: This pressure bar mechanical lug installs in the field without crimping tools; the bar tightens down to clamp and secure the conductor.
• Field-Serviceable: Because the conductor is held by a pressure bar rather than a permanent crimp, the connection can be inspected, re-tightened, or re-terminated as needed.
• SCRULUG™ Series: Part of Burndy's established SCRULUG™ line of one-piece mechanical connectors.
