Thomas Betts 18RAD-183 Female Wire Disconnect 22-18 Awg

Product Description

The THOMAS BETTS 18RAD-183 is a fully insulated female wire disconnect terminal designed for reliable quick-connect wiring applications in electrical and control circuit assemblies. The terminal accepts 22-18 AWG wire and features a 0.187 inch tab width, making it compatible with standard 3/16 inch male tab connectors. The red vinyl insulation provides full coverage over the barrel and seam, protecting against accidental contact and short circuits. This terminal is suitable for use by licensed electricians, HVAC technicians, and panel wiring professionals who require a secure, vibration-resistant connection in control wiring harnesses and equipment assemblies.

This female disconnect is used in residential and light commercial electrical applications including HVAC control wiring, appliance wiring, automotive electrical assemblies, and general panel wiring. The 22-18 AWG range covers common low-voltage control wire gauges found throughout HVAC systems, lighting controls, and motor starter circuits. The red color coding aids in identification and wire management during installation and service. Sold in packages of 100 units, this terminal is well suited for contractors and technicians who wire multiple control circuits in a single job.

Installation Notes

Installation is performed by licensed electricians or qualified HVAC technicians following applicable NEC guidelines. De-energize all circuits before terminating or replacing disconnect terminals. Use a properly sized wire stripper and a calibrated ratchet crimping tool rated for vinyl-insulated terminals in the 22-18 AWG range to ensure a gas-tight crimp. Do not solder over the crimp, as this can reduce the terminal's ability to absorb vibration and may cause conductor brittleness at the joint.
