Green wing-style twist-on wire connector in polypropylene finish

3M Industrial

3M Industrial SG-G Green Twist-On Wire Connector 10 AWG Max

SKU CH-HHXS-DK0PH

Green twist-on wire connectors join solid or stranded copper wires from 14 to 10 AWG, rated for 600 V and 221 degrees F

  • Secure copper connections up to 10 AWG with steel contact
  • Wing-style design speeds installation on solid or stranded wire
  • UL Listed for 600 V applications ensuring code compliance
  • Green polypropylene insulation resists heat up to 221 °F
  • Handles wire combinations from three 14 AWG to three 10 AWG

Green twist-on connector for 10 AWG max

This green polypropylene twist-on connector is rated for copper conductors up to 10 AWG and down to 14 AWG. It carries a 600 V maximum voltage rating and a 221 °F maximum operating temperature. The wing-style body provides grip for hand installation. UL listed for code-compliant work.

Replaces loose tape joints or undersized caps

Use it when a junction needs a secure mechanical splice that will not loosen under vibration. The steel spring bites solid or stranded copper from 14 AWG up to three 10 AWG conductors. The jump is worth it when the existing connector cannot accommodate the full wire fill or temperature rating required by the circuit.

Handles three 10 AWG conductors per connector

The maximum combination of three 10 AWG wires fits comfortably inside the polypropylene shell. Beyond that fill the spring cannot maintain reliable contact pressure and the insulation rating is exceeded. Minimum combination of three 14 AWG wires ensures the spring still closes firmly on smaller gauges.

Questions about this item

What wire-gauge range does the green 3M twist-on connector accept?

It handles solid or stranded copper from 14 AWG up to 10 AWG, with a minimum combination of three 14 AWG and a maximum of three 10 AWG wires.

How do you install the wing-style connector without damaging the wires?

Strip each conductor to the recommended length, hold wires parallel, push them into the connector and twist the wings clockwise until the insulation bites — do not pre-twist the strands.

When should the polypropylene connector be replaced in a 600 V circuit?

Replace it if the housing shows heat discoloration, cracking, or if the spring feels loose after exposure near the 221 °F temperature rating.
