Built from one-piece, seamless, high-conductivity copper, this lug is rated for systems up to 35 kV and accommodates 250 kcmil conductors. It features a 1\/2 inch stud size, an inner diameter of 0.590 inches, and a barrel length of 3.380 inches. The yellow color coding aids in quick conductor size identification on the job. Licensed electricians and utility technicians install this lug in medium-voltage termination applications where a reliable, low-resistance mechanical and electrical connection is required.\u003c\/p\u003e\n\u003cp\u003eThis lug is suited for medium-voltage electrical distribution work in commercial, industrial, and utility installations. The long barrel design provides extended contact surface area with the conductor, supporting solid compression terminations. It is intended for copper conductor use only and is color-coded yellow for 250 kcmil identification. Typical install scenarios include switchgear terminations, transformer connections, and cable splicing up to 35 kV.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eOne-piece seamless construction eliminates weak points in the barrel\u003c\/li\u003e\n  \u003cli\u003eHigh-conductivity copper material supports efficient current transfer\u003c\/li\u003e\n  \u003cli\u003eRated for systems up to 35 kV\u003c\/li\u003e\n  \u003cli\u003eAccepts 250 kcmil copper conductors with a 0.590 inch inner diameter\u003c\/li\u003e\n  \u003cli\u003eLong barrel design at 3.380 inches provides extended conductor contact\u003c\/li\u003e\n  \u003cli\u003eYellow color coding for fast field identification of conductor size\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with copper conductors only at 250 kcmil.
