3M B/G+ Twist-On Wire Connector Pack 250

This pack contains 250 blue and gray twist-on wire connectors designed for copper conductors. They accept wire sizes from 14 AWG to 10 AWG and are suited for electrical professionals and automotive wiring tasks. The connectors provide a secure mechanical splice for solid and stranded wire combinations. Each unit is UL Listed and CSA Certified for code-compliant installations.

600 V Maximum Voltage and 221 °F Temperature Limit

The connectors are rated for a maximum operating voltage of 600 V and a maximum temperature of 221 degrees Fahrenheit. The polypropylene and thermoplastic elastomer insulation carries a UL 94 V-2 flammability rating. Steel contact material ensures conductivity within these defined electrical and thermal boundaries. Installations must remain within these limits to maintain safety compliance.

Wire Range 14 AWG to 10 AWG

The single specification that determines suitability is the approved wire range of 14 AWG minimum to 10 AWG maximum for this connector style. It accommodates a minimum combination of four 14 AWG wires and a maximum combination of two 6 AWG wires with up to six conductors total. Buyers needing to join wires larger than 10 AWG or smaller than 14 AWG must select a different connector model.
