Ecm Industries Llc 14-099 Ring Terminal 4 Awg 600V 4 Pack

Product Description

The ECM INDUSTRIES LLC 14-099 is a 4-pack of yellow, vinyl-insulated ring terminals designed for secure, permanent wire-to-stud connections in electrical and low-voltage wiring applications. Built for 4 AWG wire, each terminal features a vinyl-insulated barrel rated at 600 volts maximum and a temperature rating of 167 degrees F (75 degrees C). The yellow color coding follows standard industry conventions for 4 AWG conductor identification, making termination work faster and reducing miswiring risk. These terminals are sold in a carded 4-pack, suitable for service vans and job-site electrical kits used by licensed electricians and HVAC technicians.

Ring terminals of this type are used wherever a wire must be fastened to a threaded stud, lug, or binding post. Common applications include control panel wiring, equipment grounding, motor lead terminations, and HVAC disconnect block connections. The 1/2 inch ring opening accommodates standard stud sizes found in residential and light commercial electrical equipment. The vinyl insulation barrel provides strain relief and helps protect the crimped connection from abrasion and incidental contact.

Key Features

• 4 AWG wire gauge — sized for high-current applications requiring heavier conductors
• 600V maximum voltage rating — suitable for most residential and light commercial branch circuit terminations
• Temperature rated to 167 degrees F (75 degrees C) — compatible with standard wiring environments
• Vinyl-insulated barrel — provides insulation coverage and strain relief at the crimp zone
• Yellow color coding — industry-standard color for 4 AWG terminal identification
• 1/2 inch ring inner diameter — fits common stud sizes on lugs, busbars, and equipment terminals

Compatibility

Designed as a standard 4 AWG vinyl-insulated ring terminal suitable for use with copper conductors in residential and light commercial electrical termination applications where 600V-rated connections are required.

Installation Notes

Ring terminals should be installed by a qualified electrician or licensed HVAC technician following applicable NEC requirements. Always de-energize and lock out the circuit before making or inspecting terminations. Use a ratcheting crimp tool rated for 4 AWG terminals to achieve a proper mechanical crimp — do not rely on solder alone or use an undersized tool. Inspect the vinyl insulation barrel after crimping to confirm no cracking or displacement has occurred.
