Ecm Industries Llc 10-003 Wire Connector 22-14 Awg 100 Pack

Product Description

The ECM INDUSTRIES LLC 10-003 is an orange, small-format twist-on wire connector sold in a 100-count box. Rated for 22 to 14 AWG copper wire, it uses a square spring insert inside a polypropylene shell to create a secure, vibration-resistant termination. These connectors are a standard consumable for licensed electricians and HVAC technicians performing low-voltage and line-voltage wiring on residential and light commercial equipment. The polypropylene housing resists heat and common chemicals encountered in field conditions. Each connector is color-coded orange for quick gauge identification on the job.

This connector is suited for copper-only applications across a wide range of installations: thermostat wiring, control board connections, junction box terminations, motor lead splices, and general branch-circuit work. The 22-to-14 AWG range covers the majority of low-voltage signal wiring and many line-voltage applications found in HVAC systems, plumbing controls, and electrical panels. The 100-count boxed format is practical for service vans and job-site stock.

Key Features

• Accepts 22 to 14 AWG copper wire for broad application coverage
• Square spring insert provides a firm, twist-resistant grip on conductors
• Polypropylene shell resists heat, moisture, and common field chemicals
• Orange color coding allows fast gauge identification during installation
• Copper wire only — not rated for aluminum conductors
• Boxed 100-count format designed for van stock and job-site use

Compatibility

Designed for use with copper conductors in the 22 to 14 AWG range. Suitable for standard twist-on connector applications in residential and light commercial electrical, HVAC control wiring, and related trade work.

Installation Notes

Installation is performed by a licensed electrician or qualified HVAC technician in accordance with the NEC and applicable local codes. Always de-energize the circuit at the breaker or disconnect and verify absence of voltage before making or breaking any wire termination. Strip conductors to the manufacturer-recommended length, hold conductors parallel, and twist the connector clockwise until firm resistance is felt. These connectors are rated for copper wire only — do not use on aluminum conductors.
