What is the correct term for a live wire in electrical terminology?

The term "ungrounded conductor" refers specifically to a live wire in electrical terminology. This designation implies that the wire carries current that is not connected to the ground, thereby making it a hot or live wire. In electrical systems, an ungrounded conductor is essential for completing a circuit and delivering power to devices. It is typically color-coded (commonly black or red in residential wiring) to indicate its function as a live wire.

In contrast, the other terms refer to different electrical function areas. A grounded conductor typically refers to a wire that is connected to the earth, intended to provide a path for fault currents to enhance safety. A current-carrying conductor is too broad since it doesn't specify if the conductor is grounded or ungrounded. Lastly, a neutral conductor serves as the return path for current and is designed to carry current in normal operation, but it is typically grounded in systems for safety and circuit stability. Thus, referring to a live wire specifically as an ungrounded conductor provides clarity and precision in electrical terminology.
