Which range of solid conductor sizes is typical for low-voltage cables?

• A. AWG 20 to AWG 8
• B. AWG 26 to AWG 12
• C. AWG 24 to AWG 14
• D. AWG 28 to AWG 10

Answer: (D)

Solid conductor sizes in low-voltage cabling span a wide range because these systems include everything from small signaling or sensing wires to higher-current control feeds. In fixed installations, using solid conductors helps with reliability and easier terminations in boxes and conduits. The range from AWG 28 to AWG 10 covers the common needs: very small wires for low-current circuits, mid-range sizes for general control and data runs, and larger wires for higher-current feeders and to keep voltage drop in check over short distances. That broad span is why this option best represents typical low-voltage cabling sizes. The other ranges omit one end or the other, making them less representative of what’s actually encountered.
