3M Twist-On Wire Connectors 100 Pack

These 3M twist-on wire connectors come in a pack of 100 for residential and light commercial electrical work. They join solid or stranded copper conductors ranging from 22 AWG to 12 AWG. The winged design provides grip for hand installation without tools. Electricians and DIYers use them for lighting, outlet and switch wiring.

600 V 221 °F Maximum Ratings

The connectors are rated for a maximum of 600 volts and an operating temperature of 221 degrees Fahrenheit. Insulation uses polypropylene and thermoplastic elastomer with a UL 94 V-2 flammability rating. They hold up to six conductors with a maximum combination of five 12 AWG wires. The steel contact springs ensure a secure mechanical and electrical connection.

18 to 12 AWG Wire Range Decides Fit

The critical specification is the approved wire range of 18 AWG minimum to 12 AWG maximum for multi-wire combinations. Single wires from 22 AWG to 8 AWG are also accepted. Buyers needing to join larger conductors or more than six wires must select a different connector size. These are not suitable for aluminium conductor applications.

Questions about this item

Should I use these for 18 AWG or 12 AWG wires?

They cover both. The minimum combination is two 18 AWG conductors and the maximum is five 12 AWG conductors, with a single-wire range from 22 AWG up to 8 AWG.

What does the 600 V rating mean when I install them?

It means the connector is certified for circuits up to 600 volts, so it is suitable for standard residential and light-commercial wiring at that voltage level.

Are these UL listed and CSA certified for code compliance?

Yes. They carry UL listing, CSA certification and CE marking, and meet UL 94 V-2 flammability requirements for electrical installations.
