Overview
The Burndy YA-L N350 350 MCM compression lug is a heavy-duty copper terminal designed for terminating 350 kcmil (kilowatt circular mil) copper conductors in industrial, utility, and commercial electrical applications. These HYLUG™-series connectors feature red color coding and die index 324-18 for easy identification during installation. Manufactured from seamless high-conductivity electrolytic copper with electro-tin plating, they deliver reliable low-resistance electrical connections rated for up to 35 kV.
