MIDWEST FASTENER CORP 76183 #7 Ceramic Twist-on Wire Connector 8PK

Ceramic twist-on connectors for copper wiring

These ceramic twist-on wire connectors join two or more copper conductors in residential or light-commercial electrical circuits. The #7 size suits common branch-circuit gauges and the ceramic body resists heat better than standard plastic shells. Electricians and DIY installers use them for lighting, receptacle and junction-box splices where a durable, high-temperature connection is required. The eight-piece pack covers several joints on a typical job.

Heat resistance under continuous load

Ceramic construction withstands the sustained temperatures found on lighting circuits and motor leads without softening or cracking. The threaded interior bites securely into copper strands so the joint remains tight through thermal cycling. These connectors are not rated for aluminum conductors, so they must not be used on aluminum branch circuits or aluminum-to-copper splices. Installers should verify conductor material before use.

#7 size determines wire-range compatibility

The #7 designation sets the minimum and maximum copper conductor combinations the connector can accept. Choosing the wrong size leaves strands loose or prevents the cap from seating fully, creating a fire hazard. Buyers who need to splice larger feeders or smaller control wires must select a different size; this pack only addresses the #7 range.
