Burndy QA282N Mechanical Lug 4/0 AWG

The Burndy QA282N is a copper mechanical lug designed for terminating a single stranded copper conductor. It accepts wire sizes from 3/0 AWG up to 4/0 AWG maximum and provides a two-hole mounting pattern with 1/2 in stud holes. The connector is rated for 600 V and a maximum operating temperature of 194 Degrees F.

Check conductor size and mounting pattern

Verify that your stranded copper wire falls within the 3/0 AWG minimum to 4/0 AWG maximum range before ordering. Confirm the mounting surface accommodates two holes with 0.56 in diameter spaced 1.75 in apart. The hex head requires a suitable driver and the tongue measures 3.12 in long by 1 in wide by 0.25 in thick for clearance planning.

Replaces single-hole or smaller-gauge lugs

This lug upgrades from single-hole terminals or connectors rated for smaller wire gauges when a dual-hole mount and 4/0 AWG capacity are required. The jump is worth it when the installation demands the mechanical security of two 1/2 in studs and the ampacity of maximum-gauge stranded copper at 600 V. It is not for aluminum conductors or multi-conductor terminations.

Questions about this item

Does the Burndy QA282N lug come with mounting hardware for the 1/2 in stud holes or must bolts be purchased separately?

The lug itself is supplied without bolts; you will need to source two 1/2 in stud bolts and matching washers or nuts to secure the 1.75 in spaced holes.

Should I choose the 4/0 AWG maximum version or is there a smaller size for 3/0 AWG conductors?

This single model accepts stranded copper from 3/0 AWG minimum up to 4/0 AWG maximum, so one lug covers both sizes.

With a 600 V rating and 194 °F temperature limit, can the lug run continuously at full load inside a warm enclosure?

Yes, the copper body and hex-head set screw are rated for 600 V and 194 °F maximum operating temperature, suitable for continuous use within those limits.
