Nodexa W5 Blue Winged Wire Connectors — 18–8 AWG Twist-On Wire Nuts (10, 25 & 100-Pack)

When a splice runs heavier than a lighting circuit — a bundle of #12s at a junction, a #10 feeding a dedicated run, a mix landing in one box — the blue W5 is the connector that closes it. These Nodexa W5 winged connectors handle the 18 to 8 AWG range, taking combinations up to a #10 with a #8 that the smaller tan caps can't seat, and they come three ways: a 10-pack for the service call, a 25-pack for the room, and the 100-count bag for the panel that needs a box of them. Swept wings give the leverage to twist a full combination home by hand, and the fixed square-wire spring threads itself onto the conductors as it turns, pulling them into a tight, gas-tight grip without pre-twisting. A deep thermoplastic skirt guards against flash-over and turned-back strands, and the shell is flame-retardant and rated to 105°C. Rated 600V for copper-to-copper connections, UL Listed and CQC certified, CE and RoHS compliant — a NorthLine Signature electrical part, stocked in the quantity the job actually calls for.
