Yellow twist-on wire connector, thermoplastic shell

POWER FIRST

POWER FIRST Twist-On Wire Connector Yellow 8 AWG Max

SKU CH-FJ1H-76EFC

Twist-on wire connector joins up to seven copper conductors from 20 AWG to 12 AWG at 600 V with a 221 °F temperature rating

  • Product typeElectrical Connectors
  • Handles up to 7 conductors for versatile splicing
  • UL 94 V-2 rating resists flame spread
  • CSA certified for code-compliant installations
  • 600 V rating suits standard residential wiring
  • Thermoplastic shell withstands 221 °F operating temperature

What the product is

The POWER FIRST Twist-On Wire Connector in yellow joins copper conductors in light fixtures and house wiring. It accepts a minimum combination of three 20 AWG wires and a maximum of two 12 AWG with two 14 AWG wires. Up to seven conductors can be secured per connector. UL listed under E113650 and CSA certified to 175604UL with a UL 94 V-2 flammability rating.

Thermals noise and power draw

The thermoplastic housing is rated for a maximum operating temperature of 221 degrees Fahrenheit. The connector handles up to 600 volts in normal service. Steel contact material provides a reliable electrical path without generating audible noise. No external power supply is required for this passive component.

Sustained load behaviour

Under continuous load the connector maintains its grip on up to seven conductors within the stated wire-range limits. The UL 94 V-2 rating confirms the housing resists flame spread during prolonged heating cycles. Compatible with installation tool model number 4 for consistent repeat terminations. Not suited for applications exceeding 600 volts or conductor sizes larger than 8 AWG maximum.

Questions about this item

How do I install the ZORO SELECT twist-on connector without stripping the wires too short?

Strip each copper conductor to the length recommended for the No. 4 installation tool, twist the wires together firmly, then screw the yellow connector on until the insulated skirt covers all bare metal.

Will the steel contact springs inside the yellow connector fatigue and need replacement after repeated thermal cycles?

The steel contacts are rated for continuous operation at 221 degrees F and carry UL 94 V-2 flammability certification, so they do not require scheduled replacement under normal residential wiring conditions.

At what point does the 600 V rating become the limiting factor when the connector is used on a heavily loaded 12 AWG circuit?

The 600 V maximum voltage is the first hard limit; as long as the circuit stays at or below that potential, the connector’s temperature rating of 221 degrees F governs sustained current capacity.
