Burndy KPU34A26AC 500 Kcmil Al-cu Parallel Tap Connector

Product Description

The BURNDY KPU34A26AC is an aluminum-to-copper (Al-Cu) parallel tap connector rated for 500 KCMIL conductor applications. Designed for use in high-current electrical distribution systems, this compression-style tap connector allows a branch conductor to be tapped off a main run without cutting or interrupting the main conductor. Licensed electricians and electrical contractors install this type of fitting during service entrance work, feeder runs, and industrial distribution panel connections where dissimilar metal conductors must be joined reliably and in compliance with applicable codes.

This connector is suited for commercial and industrial electrical installations where aluminum main conductors must interface with copper tap conductors, or vice versa. It is commonly used in utility metering, switchgear, load centers, and large feeder assemblies. The parallel tap configuration keeps both conductors in line, reducing installation complexity in congested conduit or enclosure environments.

Key Features

• Rated for 500 KCMIL conductor size on the main run
• Aluminum-to-copper (Al-Cu) compatibility prevents galvanic corrosion issues when used as designed
• Parallel tap design allows branch connection without cutting the main conductor
• Compression termination style provides a secure, low-resistance electrical joint
• Suitable for high-current feeder and service entrance applications

Compatibility

Designed as an OEM-style compression parallel tap connector for 500 KCMIL aluminum and copper conductors in commercial and industrial electrical distribution systems. Consult BURNDY tooling charts to confirm the correct compression die set for this connector.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize and lock out the circuit before installing any compression connector. Use only the manufacturer-specified compression tool and die to achieve a proper crimp. Inspect conductor ends for nicks or corrosion before insertion, and apply appropriate oxide inhibitor compound when joining aluminum conductors.
