22-12 AWG twist-on wire connectors

These 3M twist-on wire connectors accept copper conductors from 22 AWG up to 12 AWG. They are rated for 600 V and a maximum operating temperature of 221 Degrees F. The pack contains 100 pieces suited for residential and light commercial wiring tasks.

Check wire gauge and voltage before use

Verify that your conductors fall within the 22 to 12 AWG range and that the circuit does not exceed 600 V. Ensure the insulation material is compatible with polypropylene and thermoplastic elastomer. Confirm the connection meets local electrical codes for the intended application.

Blue/Orange colour coding aids identification

The connector shell uses a blue and orange colour scheme for quick visual identification on the job site. A steel contact with zinc finish provides a secure mechanical grip when twisted onto stripped wires. The UL 94 V-2 flammability rating and CSA and UL listings confirm compliance with recognised safety standards.

Questions about this item

What comes in the package and is any tool needed to install the connectors?

The pack contains 100 twist-on wire connectors. No separate tool is required — the connectors are installed by hand.

Should I choose these blue/orange connectors or a different colour for a 12 AWG solid copper wire?

The blue/orange model accepts a maximum single wire size of 12 AWG and a maximum combination of three 12 AWG conductors, so it covers that gauge.

How does the 600 V rating apply when the connector is used in a standard household circuit?

The connector is UL listed for up to 600 V, which exceeds typical residential voltages, so it is suitable for ordinary household wiring.
