- Wing-style grip speeds up twist-on connections
- Accepts solid or stranded copper from 14 AWG minimum
3M Blue Twist-On Connector 6 AWG
This 3M Industrial twist-on wire connector joins solid or stranded copper conductors in electrical installations. The wing-style polypropylene shell provides grip for hand tightening without tools. UL Listed for 600 V maximum and rated to 221 degrees F operating temperature. Suited for residential, commercial and light industrial wiring tasks.
Wire-range 14 to 6 AWG copper
The connector accepts a single conductor from 14 AWG up to 6 AWG. Minimum combination is six 14 AWG wires; maximum combination is three 8 AWG wires. Steel contact inserts ensure mechanical hold and electrical continuity across the approved range. Exceeding the stated combinations voids the listing and risks overheating.
Handles up to three 8 AWG conductors
Within the UL-listed limits the connector comfortably splices multiple branch-circuit conductors in junction boxes. It runs out when the wire count or gauge exceeds the published maximum combination, requiring a larger connector or alternative splicing method. Not suitable for aluminium conductors or voltages above 600 V.

Questions about this item
What does the 6 AWG maximum single-wire size mean when I am making a splice?
You can join one solid or stranded copper conductor as large as 6 AWG, down to 14 AWG, inside the same connector.
How does the 600 V rating limit the circuits I can use this on?
The connector is UL Listed for circuits up to 600 V, so it is approved for standard residential, commercial and industrial wiring within that voltage.
What physical space and wire preparation does the wing-style body need?
The polypropylene-insulated wing connector accepts solid or stranded copper wire from 14 AWG to 6 AWG and is twisted on by hand; no special tool is required.
