Your default gray wire is phase 3 of the line in the AC code. In DC circuits, a gray wire is negative.
What do the thread colors mean?
The simple explanation is that each color used on electrical wires has a specific meaning, with different colors indicating different types of circuits and purposes. NEC establishes the following color standards for electrical wiring: Ground wires: green, green with a yellow stripe or bare copper. Neutral conductor: white or gray.
