The ECM INDUSTRIES LLC 10-004 is a yellow medium wire connector sold in a 100-count box. It is designed for joining copper conductors in the 18 to 12 American Wire Gauge (AWG) range. The connector body is made from polypropylene and uses a square spring internally to secure the wire bundle. Electricians and HVAC technicians use twist-on connectors like this one during panel wiring, low-voltage control circuit work, fixture installations, and general branch-circuit terminations. The yellow color coding corresponds to the 18 to 12 AWG capacity range, making it easy to grab the correct connector on the job.
This connector is suited for residential and light commercial electrical work where copper wire terminations are required. Common applications include junction box splices, thermostat wiring, lighting circuit connections, and HVAC control wiring. The 100-count boxed packaging is sized for service vehicles and job-site supply stock. These connectors are appropriate for dry and damp locations where standard twist-on connectors are permitted by the applicable electrical code.
Designed for use with copper conductors in the 18 to 12 AWG range. Not rated for aluminum wire. Suitable as a standard twist-on wire connector in residential and light commercial electrical applications.
Installation is performed by licensed electricians or qualified HVAC technicians in accordance with the National Electrical Code (NEC). De-energize the circuit at the breaker and verify absence of voltage with a meter before making any wire connections. Strip conductors to the connector manufacturer's recommended strip length, hold wires parallel, and twist the connector clockwise until secure. Do not use these connectors on aluminum wire.
