AWG (American Wire Gauge) converters translate between AWG numbers and actual wire diameter/cross-sectional area.

단계별 가이드

  1. 1AWG scale: smaller number = larger wire
  2. 2Each step decreases diameter by ~1.123× (logarithmic)
  3. 3Cross-sectional area roughly doubles every 3 AWG sizes

풀어진 예시

입력
10 AWG copper wire
결과
2.588 mm diameter, 5.26 mm² area, ~31 ampere rating
Typical household branch circuit

피해야 할 일반적인 실수

  • Confusing AWG number with diameter (smaller number = larger wire)
  • Using incorrect ampacity table (varies by insulation type)

자주 묻는 질문

Why the inverse sizing?

Historical convention; AWG 0 was largest, lower numbers larger. Counterintuitive but established.

How does wire gauge relate to current capacity?

Ampacity depends on material, insulation, installation (bundle, conduit). Larger cross-section carries more current.
