the diameter of a no. 6 wire is larger than which one of the following?
a) no. 12 wire
b) 250 kcmil cable
c) no. 4 wire
d) no. 2/0 wire

Explanation:

Step1: Recall wire gauge knowledge

In the American wire gauge (AWG) system, as the gauge number increases, the wire diameter decreases. So a lower - numbered wire has a larger diameter than a higher - numbered wire.

Step2: Analyze each option

• Option A: No. 12 wire has a higher gauge number than No. 6 wire. Since higher gauge number means smaller diameter in AWG, No. 6 wire has a larger diameter than No. 12 wire.
• Option B: 250 kcmil (kilo - circular mils) is a measure of wire cross - sectional area. A 250 kcmil cable has a much larger cross - sectional area (and thus larger diameter in most cases when comparing to standard AWG wires) than a No. 6 wire.
• Option C: No. 4 wire has a lower gauge number than No. 6 wire. So No. 4 wire has a larger diameter than No. 6 wire.
• Option D: No. 2/0 (which is equivalent to 2/0 AWG or 200 kcmil in some cross - sectional area - related comparisons) has a larger diameter than No. 6 wire.

Answer:

A. No. 12 wire
