Ma-line MA02543-1 Insulated Spade Terminal 12-10 Awg

Product Description

The MA-LINE MA02543-1 is an insulated flared spade terminal designed for secure, vibration-resistant connections in electrical wiring applications. Rated for 12-10 AWG wire, this terminal accepts a No. 10 stud and features a flared barrel entry that guides wire strands during insertion, reducing mis-feeds and strand damage. Each package contains 15 terminals. Insulated spade terminals of this type are standard inventory for electricians, HVAC technicians, and panel wiring professionals who require reliable mechanical and electrical terminations on screw-type studs or binding posts.

This terminal is suited for use in residential and light commercial wiring scenarios where a removable, screw-fastened connection is preferred over a permanent crimp-to-lug arrangement. Typical applications include control panel wiring, equipment grounding connections, motor terminal blocks, and service disconnect assemblies. The 12-10 AWG range covers common branch-circuit and equipment-wire sizes used across HVAC, electrical, and pool equipment installations. The 15-piece pack format supports single-job quantities without excess.

Key Features

• Flared barrel entry guides wire strands for clean, consistent crimps
• Insulated construction isolates the connection point after termination
• Accepts 12-10 AWG wire, covering common branch-circuit and equipment wire sizes
• Fits No. 10 stud for use with standard screw terminals and binding posts
• 15-terminal pack provides practical single-job quantity

Compatibility

Designed as a standard insulated flared spade terminal for use with No. 10 studs and 12-10 AWG wire in general electrical, HVAC control, and light commercial wiring applications.

Installation Notes

Installation is performed by licensed electricians or qualified HVAC technicians in accordance with applicable NEC requirements. De-energize and lock out the circuit before terminating or removing any spade connection. Use a calibrated ratcheting crimp tool sized for insulated terminals to ensure a full, consistent crimp on the barrel. Do not over-torque the stud fastener, as this can distort the spade tab and compromise the mechanical connection.
