Easy-to-disconnect connector locks and other cord-locking mechanisms are convenient tools for anchoring cords to inlets to prevent abrupt disconnects, but not all manufactured versions are created equal. Avoid easy-to-disconnect locking mechanisms which gouge or shave away the ground blade of the inlet during abrupt disconnects or improper usage and removal.

Individual conductor wires are extruded in resin before 2- and 3-wire conductors are cabled into a “twist” of conductors before jackets are extruded over them. The jacketing process is similar to insulating copper wires on the extrusion line. The main difference is jacketing uses more extruded resin making it more time-consuming than insulating. Prior to extrusion, talc is applied to the twisted, insulated conductors which acts as a release-agent for stripping the jacket. This is especially user-friendly when a few millimeters of jacket need to be stripped for crimping wires.
