Mechanical Lug for 350 kcmil Copper

The Burndy Q2A312N is a copper mechanical connector rated for 600 V and a maximum operating temperature of 194 Degrees F. It accepts two stranded copper conductors ranging from 250 kcmil to 350 kcmil. The terminal features a two-hole tongue with .56 in diameter holes spaced .75 in apart for a secure mounting.

Verify Conductor Size and Stud Compatibility

Before ordering confirm that your installation uses stranded copper wire within the 250 kcmil to 350 kcmil range. The lug requires a 1/2 in stud and provides two mounting holes with .56 in diameter and .75 in spacing. Ensure the tongue dimensions of 3.09 in length 2.38 in width and .31 in thickness fit the available space.

Thermal and Electrical Performance

Rated for continuous operation up to 194 Degrees F the lug maintains reliable conductivity under normal load. The solid copper body and dual-conductor design distribute current evenly across both terminations. Mechanical hex-head screws provide a gas-tight connection that resists loosening from vibration or thermal cycling.

Questions about this item

Does the lug ship with mounting hardware or do I need to buy 1/2 in studs and hex bolts separately?

The connector body is supplied alone; 1/2 in studs, nuts and hex-head bolts for the .56 in holes must be sourced separately.

When should I choose the 350 kcmil two-conductor version instead of a single-conductor lug?

Select this Q2A312N when you need to terminate two copper conductors up to 350 kcmil each on the same 1/2 in stud with .75 in hole spacing.

Will the 600 V rating hold at the 194 °F maximum temperature inside a live panel?

Yes, the copper body is rated for continuous operation at 600 V up to the 194 °F limit.
