Thomas Betts 14RB-2577C Female Wire Disconnect 16-14 Awg

Product Description

The THOMAS BETTS 14RB-2577C is a fully insulated female wire disconnect designed for reliable electrical terminations in control wiring, appliance wiring, and general-purpose electrical assemblies. The connector accepts 16-14 AWG conductors and features a 0.25 inch tab width for mating with standard male spade terminals. The nylon insulation is rated UL 94 V-2 for flame resistance and is colored blue for quick visual identification of the 16-14 AWG wire range during installation and inspection. Sold in a package of 100 pieces, this disconnect is a standard stock item for electricians, HVAC technicians, and panel assemblers who need consistent, code-compliant terminations.

This female disconnect is suited for residential and light commercial wiring applications including HVAC control circuits, appliance harnesses, automotive auxiliary wiring, and low-voltage panel terminations. The fully insulated nylon sleeve protects against incidental contact with adjacent conductors and hardware. It is a common choice when a removable, serviceable connection is preferred over a soldered or permanently crimped joint.

Installation Notes

Installation is performed by licensed electricians or HVAC technicians using an appropriately sized ratcheting or fixed-die wire terminal crimper rated for insulated disconnects. Always de-energize the circuit and follow lockout/tagout procedures before terminating or removing connectors. Do not use pliers or non-rated tools to crimp, as an improper crimp can result in a high-resistance connection or pull-out failure. Verify conductor strip length matches the barrel depth before crimping.
