AWG (American Wire Gauge) converters translate between AWG numbers and actual wire diameter/cross-sectional area.
ステップバイステップガイド
- 1AWG scale: smaller number = larger wire
- 2Each step decreases diameter by ~1.123× (logarithmic)
- 3Cross-sectional area roughly doubles every 3 AWG sizes
解いた例
入力
10 AWG copper wire
結果
2.588 mm diameter, 5.26 mm² area, ~31 ampere rating
Typical household branch circuit
避けるべきよくある間違い
- ✕Confusing AWG number with diameter (smaller number = larger wire)
- ✕Using incorrect ampacity table (varies by insulation type)
よくある質問
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.
