The green wire in a four wire cable which feeds an electric motor is called a ___.

The green wire is the protective earth, or ground, conductor. Its job is to provide a low-impedance path to earth so that any fault current flowing to the motor’s metal frame is safely directed to the ground. This keeps the frame at a safe potential and helps trip the overcurrent protection quickly if something goes wrong. Ground wires are color-coded green (often with a green-yellow stripe) to distinguish them from live (hot) and neutral conductors. The neutral carries current back to the source (typically white), the live/hot carries current from the source (typically black or red), and shield wires are for EMI shielding, not for safety grounding in a standard power cable. So the green wire in this four-wire motor feed is the ground wire.
