The SUPCO wc-o-cj is an orange twist-on wire connector sold in a 100-piece jar. It is designed for making fast, secure connections between copper conductors in electrical and low-voltage wiring applications. The connector uses a specialized internal spring that grips wires in fewer twists than standard connectors. The exterior is ribbed for a firm grip, even in tight spaces or with gloved hands. Rated at 600 volts and listed to UL 486C, this connector meets the requirements electricians and HVAC technicians need for field wiring work on residential and light commercial systems.
The wc-o-cj suits typical field wiring tasks where copper conductors in the 22 AWG to 14 AWG range need to be joined. Common applications include control circuit wiring, splice connections in junction boxes, and equipment hookups during installation or service. The 100-piece jar format is suited for electricians and HVAC technicians who work through connectors quickly on multi-unit jobs or service routes. The orange color coding helps with quick identification by wire gauge range on the job.
Designed for use with copper wire only in the 22 AWG to 14 AWG range. Suitable for use in residential and light commercial electrical, HVAC control wiring, and similar low-voltage and line-voltage splice applications where a UL 486C listed twist-on connector is required.
Wire connectors of this type are installed by licensed electricians and HVAC technicians in accordance with the National Electrical Code (NEC). Always de-energize the circuit at the breaker or disconnect before making or breaking any wire connection. Strip conductors to the appropriate length for the connector size before twisting. Do not use this connector with aluminum wire, as it is rated for copper conductors only.
