3M 7010297780 Ring Terminal 12-10 Awg Crimp 1/2 Inch 50 Pack

Product Description

The 3M 7010297780 is a partially insulated circular ring terminal designed for crimp connections on copper conductors ranging from 12 to 10 AWG. The terminal features a copper contact with a blue vinyl insulation sleeve and accepts a 1/2-inch stud. It is used to create a secure, low-resistance mechanical and electrical connection at termination points in control panels, HVAC equipment wiring, electrical enclosures, and general trade wiring applications. Licensed electricians and HVAC technicians install this terminal type when terminating stranded or solid copper wire to bus bars, lugs, or equipment ground studs. Each package contains 50 terminals.

This ring terminal is suited for residential and light commercial wiring applications where a 12 AWG or 10 AWG conductor must be landed at a screw or stud termination. Common install scenarios include control wiring in HVAC air handlers, condenser units, electrical panels, and motor control circuits. The blue color coding follows standard industry convention for the 12 to 10 AWG wire range, making it easy to sort and identify during installation. The partially insulated design provides grip near the barrel while leaving the ring exposed for direct contact at the stud.

• Sold in a 50-piece package for jobsite and bench stock use

Compatibility

Designed as a crimp-style ring terminal for 12 to 10 AWG copper conductors requiring a 1/2-inch stud termination in electrical, HVAC, and control wiring applications.

Installation Notes

Installation should be performed by a licensed electrician or qualified HVAC technician in accordance with NEC requirements for the circuit type and voltage rating. De-energize the circuit completely before terminating any conductors. Use a calibrated ratchet crimping tool rated for the terminal and wire size to achieve a proper crimp — do not substitute pliers or uncalibrated tools. Inspect the crimped barrel for deformation or wire pullout before energizing.
