Ecm Industries Llc 16-003N GB3 Wire Connector 100 Pack

Product Description

The ECM INDUSTRIES LLC 16-003N is a small, orange, twist-on wire connector designed for making secure, code-compliant electrical splices in residential and light commercial wiring applications. This GB3 Wire Guard connector accepts 22 to 14 AWG copper conductors and features a polypropylene flame-retardant shell for added safety. The square spring steel insert creates firm, vibration-resistant contact between conductors, reducing the risk of loose connections over time. Sold in a 100-count pack stored in a clear reusable jar, the 16-003N is a standard stock item for electricians and HVAC technicians who regularly terminate low-voltage and line-voltage circuits.

The 16-003N is suited for splicing copper conductors in branch circuit wiring, control wiring, fixture connections, and low-voltage thermostat wiring. The 22 to 14 AWG range covers a wide variety of field applications, from small-gauge sensor leads up to standard 14 AWG branch circuits. The orange color coding helps technicians quickly identify connector size during installation. The clear storage jar keeps connectors organized and accessible on the job site or in a service van.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize the circuit and verify absence of voltage with a meter before making or breaking any connections. Strip conductors to the appropriate length, hold wires parallel, and twist the connector clockwise until firm resistance is felt. Do not use with aluminum conductors unless the connector is specifically rated for that application.
