Burndy K3A29U2N 250 Kcmil Al-cu Compression Terminal 2-hole

Product Description

The BURNDY K3A29U2N is a dual-hole compression terminal designed for use with 250 KCMIL aluminum or copper conductors. This type of terminal provides a secure, low-resistance mechanical and electrical connection by permanently deforming the barrel around the conductor during installation. It is commonly installed in panelboards, switchgear, and large junction enclosures where high-current conductors require a reliable, code-compliant termination. Licensed electricians and electrical contractors are the primary installers. The two-hole mounting configuration distributes mechanical load across the lug body and helps maintain stable contact at the bus bar or equipment stud.

This terminal is suited for residential service entrance applications, commercial distribution panels, and industrial equipment terminations where 250 KCMIL conductors are specified. The aluminum-copper (Al-Cu) rating means it accepts both aluminum and copper wire, making it a versatile choice when conductor material may vary by job or phase. It is appropriate for use in dry, damp, or wet locations depending on the enclosure rating of the equipment it is installed in.

Key Features

• Rated for 250 KCMIL aluminum or copper conductors
• Two-hole barrel design for secure bus bar or equipment mounting
• Compression-style termination ensures a permanent, low-resistance connection
• Al-Cu dual rating accommodates both aluminum and copper conductors
• Compact form factor suitable for panel and switchgear installations

Compatibility

Designed as an OEM-style compression terminal for use with 250 KCMIL aluminum or copper conductors in standard electrical distribution and service entrance applications.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements. De-energize and lock out the circuit before handling any conductors or terminals. A properly calibrated compression tool specified for the terminal size must be used to achieve the correct crimp — do not use substitute tooling. Inspect the completed crimp for full barrel deformation and secure conductor seating before re-energizing.
