Mechanical Connector for Aluminum and Copper

This mechanical connector accepts stranded copper conductors from 14 AWG up to 2/0 AWG. It is built from aluminum with a slotted head style and a single 0.25 in mounting hole. The body measures 0.750 in long with a tongue width of 0.63 in and thickness of 0.19 in.

Conductor Range 14 AWG to 2/0 AWG

The lug terminal covers a wide stranded copper range from 14 AWG minimum to 2/0 AWG maximum. This single specification determines whether the connector matches your wire gauge. Verify your conductor size falls within this window before installation.

Rated 194 Degrees F at 1,000 V

Maximum operating temperature is 194 Degrees F under a 1,000 V rating. The aluminum body dissipates heat during normal load without active cooling. No forced airflow or thermal interface material is required for typical duty cycles.

Questions about this item

What does the 2/0 to 14 AWG range mean when I install this lug?

It accepts stranded copper conductors from 14 AWG up to 2/0 AWG, so one lug covers a wide span of wire sizes without needing multiple parts.

How does the 1,000 V rating and slotted head affect the connection I can make?

The lug is rated for up to 1,000 V and uses a slotted set screw for the conductor, giving a secure mechanical clamp without specialised crimp tools.

What stud size and hole pattern does the ADR21 need for mounting?

It has a single 0.25 in diameter hole for a 1/4 in stud, with tongue dimensions of 0.84 in length by 0.63 in width and 0.19 in thickness.
