14–6 AWG twist-on connectors

These 3M B/G+ twist-on wire connectors accept solid or stranded copper conductors from 14 AWG up to 6 AWG. The blue-grey polypropylene and thermoplastic elastomer shell is UL 94 V-2 rated and CSA certified. A pack contains 50 pieces, each measuring 1.12 inches wide and 1.17 inches long.

600 V and 221 °F operating limits

Rated for a maximum of 600 volts and a continuous operating temperature of 221 degrees Fahrenheit, the connector suits standard residential and light-commercial circuits. The steel contact spring handles up to six conductors, with a minimum combination of four 14 AWG wires and a maximum combination of two 6 AWG wires.

Replaces smaller colour-coded caps

The B/G+ range bridges the gap between yellow and red connector sizes, covering combinations that would otherwise need two different products. It is not suited for aluminium conductors, for circuits above 600 V, or for installations that require a push-in or lever-style termination.

Questions about this item

Blue/Gray or a different colour — which box of 50 connectors should I pick?

The Blue/Gray colour code identifies this specific 14-6 AWG range, so choose this box when your wires fall between those sizes.

What does the 600 V rating mean when I install these in a household circuit?

The 600 V maximum covers standard residential circuits, and the connector is UL Listed and CSA Certified for those voltages.

Will the standard twist-on style work with my existing copper wiring, or do I need a special tool?

The standard twist-on design is made for copper conductors and requires no special tool — just strip and twist.
