Burndy YA1C 1-Hole Lug Copper Compression Connector

Burndy YA1C is a copper compression lug for 1 AWG conductors, designed as a straight, long-barrel terminal with a single 5/16" stud hole. It is tin-plated copper, green color coded, and UL/CSA listed with a temperature rating up to 90°C and a voltage rating up to 35 kV, optimized for reliable terminations in power-distribution wiring. The lug accepts 1 AWG stranded copper conductors and uses die code 11 (die index 11) for crimping, ensuring a precise joint when paired with Burndy crimp tools. As part of Burndy’s HYLUG copper compression family, YA1C provides a compact, single-hole termination for panel terminations, switchgear, or other equipment that require a 5/16" stud interface in a 1-hole lug. The long-barrel design adds mechanical strength and reduces conductor stress during installation. This model is listed as an uninsulated copper lug (no insulation) with a green color code in Burndy catalogs and retailer listings.
