In a typical low-voltage system, which colored wire is the neutral conductor (grounded conductor)?

• A. White Wire
• B. Green Wire
• C. Black Wire
• D. Red Wire

Answer: (A)

The neutral conductor is identified by the white wire. Neutral carries current back to the source and is bonded to earth at the main panel, so color coding uses white (or gray) to designate it. This helps distinguish it from other conductors: green is the equipment grounding conductor used for safety, while black and red are hot conductors that carry current to the load. So, the white wire serves as the neutral (grounded) conductor.
