3M 7010304078 Ring Terminal 16-14 Awg Crimp 10 Stud 25 Pack

Product Description

The 3M 7010304078 is a partially insulated circular ring terminal designed for crimp-style wire termination on 16 to 14 AWG copper conductors. The terminal features a copper contact and a blue heat-shrink insulation sleeve that provides mechanical protection over the crimped connection. Rated for use with a No. 10 stud, this terminal is suited for panel wiring, control circuits, and general electrical termination work where a secure, inspectable ring lug connection is required. It ships in a package of 25 units. Meets UL, CSA, and RoHS compliance standards, making it appropriate for both commercial and light industrial electrical work.

This terminal is used in residential and commercial electrical panel work, HVAC control wiring, and low-voltage circuit terminations. It is a standard choice when landing 16 to 14 AWG wire onto a No. 10 screw or stud terminal, such as on contactors, relay blocks, ground bars, and control boards. Electricians and HVAC technicians use this style of terminal where a removable ring connection is preferred over a spade or butt splice. The blue color coding aligns with the standard industry convention for 16 to 14 AWG wire range terminals.

Key Features

• Crimp connection for fast, tool-based termination without soldering
• Compatible with 16 to 14 AWG copper conductors
• No. 10 stud size for standard screw terminal applications
• Blue heat-shrink partial insulation sleeve for conductor protection and AWG range identification
• Copper contact material for reliable conductivity
• UL Listed, CSA Certified, and RoHS 2011 EU Compliant

Compatibility

Designed for crimp termination of 16 to 14 AWG copper wire onto No. 10 stud or screw terminal points in standard electrical and control wiring applications.

Installation Notes

Installation should be performed by a licensed electrician or qualified HVAC technician in accordance with applicable NEC requirements. De-energize the circuit before terminating any wires. Use a calibrated ratcheting crimp tool appropriate for insulated ring terminals to ensure a full, consistent crimp — do not use pliers or uncalibrated tools, as an incomplete crimp can cause high-resistance connections or terminal pullout. Inspect the heat-shrink sleeve after crimping to confirm the conductor is fully seated and the insulation is undamaged.
