POWER FIRST 5UYJ1 Twist-On Wire Connector Red 6 AWG Max

SKU CH-AWK4-35QTC

Red twist-on wing connector joins up to six copper wires from 16 AWG to 12 AWG at 600 V and 221 °F

  • Product typeElectrical Connectors
  • Connects up to 6 conductors securely
  • Handles 600 V for standard circuits
  • UL 94 V-2 rated flame-retardant shell
  • Works from 16 AWG to 12 AWG wires
  • Certified to CSA 175604 and UL E113650

Wire Connector for Copper Wiring

This red twist-on connector joins copper conductors in light fixtures and house wiring. It accepts a minimum combination of three 16 AWG wires and a maximum of five 12 AWG wires. The wing-style design allows for hand installation or use with a No. 5 tool. It is rated for 600 volts maximum.

Temperature and Flammability Limits

The connector operates up to 221 degrees F and carries a UL 94 V-2 flammability rating. Contacts are steel with a zinc finish housed in red thermoplastic. Certified to UL E113650 and CSA 175604 standards, it also meets RoHS requirements. These ratings define the safe operating envelope for the device.

Replaces Basic Wire Nuts

This model upgrades from standard twist-on caps by offering a wider wire-range capacity and a wing profile for higher torque. The jump is worth it when joining up to six conductors or when a No. 5 installation tool is preferred for repeatable connections. It is not suited for aluminium conductors or voltages above 600 V.

Questions about this item

Should I use the red 5UYJ1 for a bundle of five 12 AWG copper wires?

Yes — the red connector accepts a maximum combination of five 12 AWG copper conductors and is rated for 600 V.

What does the 221 °F temperature rating mean when the connector is inside a junction box?

It means the thermoplastic housing and steel-zinc contacts are certified to operate continuously at up to 221 °F without degrading.

How does the wing-style design affect installation with tool No. 5?

The winged body provides extra leverage so tool No. 5 can twist the connector onto the wires with less hand force.
