Wire connectors for copper conductors

The 3M O/B+ twist-on connectors join copper wires from 22 AWG up to 12 AWG in a single step. Each connector accepts a minimum of two 22 AWG conductors and a maximum of three 12 AWG conductors, with an overall limit of six conductors. The pack contains 500 pieces for residential, commercial and light-industrial wiring jobs.

Capacity from 22 AWG to 12 AWG

The blue and orange insulator handles wire combinations across the full 22 to 12 AWG range, giving installers headroom for mixed-gauge splices. It stops at three 12 AWG or six total conductors, so larger feeders or higher conductor counts need a different connector. Rated for 600 V maximum, it suits standard branch-circuit voltages.

Thermoplastic shell rated to 221 °F

The polypropylene and thermoplastic elastomer insulation carries a UL 94 V-2 flammability rating and a maximum operating temperature of 221 degrees Fahrenheit. Steel contacts maintain clamping force under thermal cycling, and the assembly is both UL Listed and CSA Certified. The connector body measures 1.17 inches in length for tight junction-box fit.

Questions about this item

Will these 3M O/B+ connectors fit the 12 AWG and 22 AWG copper wires I already have in my toolbox?

Yes, the connectors accept copper conductors from 22 AWG up to 12 AWG, covering both sizes you mentioned.

After twisting them on, how can I verify the 3M O/B+ connectors are seated correctly?

A firm tug on each wire should hold without movement, and the insulation should sit flush inside the connector with no exposed copper.

Does the 500-piece jug include any installation tools, or do I need to buy a wire stripper separately?

The jug contains only the 500 twist-on connectors; a wire stripper or other tools are not included and must be purchased separately.
