Product overview

The Burndy K3A26U2N is a three-conductor mechanical lug rated for a maximum of 2/0 AWG copper or aluminium conductors. It accepts stranded copper wire from 14 AWG up to 2/0 AWG and mounts on a 1/2 inch stud with two holes spaced 1.75 inches apart.

Installation checks

Verify that your conductors fall within the 14 AWG to 2/0 AWG stranded copper range and that the lug body material is compatible with your cable type. Ensure the mounting surface provides a 1/2 inch stud and the 1.75 inch hole spacing matches the lug's 3.06 inch tongue length and 1.95 inch width.

Sustained-load behaviour

The aluminium body is rated for continuous operation up to 194 degrees Fahrenheit at 600 volts maximum. With a tongue thickness of 0.19 inches and three terminations, the connector maintains stable contact resistance under prolonged thermal cycling without relying on spring tension.

Questions about this item

Does the lug come with mounting bolts or do I need to buy 1/2 in stud hardware separately?

The lug has two 0.56 in diameter holes spaced 1.75 in apart for 1/2 in studs; bolts, nuts and washers are not included.

Should I choose the 3-conductor version or a single-conductor lug for my 2/0 AWG copper feed?

This model terminates three conductors up to 2/0 AWG each; select it when you need three parallel connections on one lug.

Will the 600 V rating hold at the 194 °F maximum temperature inside a motor junction box?

Yes, the connector is rated 600 V at up to 194 °F, matching the stated maximum operating temperature.
