That would be the Identified conductor.
Identified conductor is also a term for the Grounded conductor, which as everyone knows, is the Grounded Neutral conductor on 1 phase circuits.
This Identified conductor does mot always have to be the grounded conductor, as in where a 1 phase 2 wire 240 volt cord was used and it has an Identified conductor on the cord.
