Definitions:

Neutral Conductor

The grounded conductor of a power system. It is connected to ground potential and is considered a current-carrying conductor. The neutral is generally white or gray in color.

Equipment Ground

A safety connection designed to protect against electrical shocks by providing a path for fault current to flow to earth ground.

Hot

Often refers to a conductor or component under voltage or at a higher temperature due to electrical resistance.

Ungrounded

Referring to an electrical system or device not connected to the ground, which can pose safety risks due to the potential for electric shock.
