Electrical Exam Term
AWG (American Wire Gauge)
A standardized system for measuring the diameter of electrical wire, where a smaller number indicates a larger wire.
Detailed Explanation
Common residential wire sizes include 14 AWG (15-amp circuits), 12 AWG (20-amp circuits), and 10 AWG (30-amp circuits). For larger conductors, sizes are expressed in kcmil (thousand circular mils). The gauge system is logarithmic — every 3-gauge decrease doubles the cross-sectional area of the wire.
