Understanding 4 AWG Cable
A 4 AWG cable is a standard conductor size defined by the American Wire Gauge (AWG) system. It is widely used in electrical systems due to its balance between conductivity, kekuatan mekanik, and installation flexibility.
Key parameters of 4 AWG cable:
- Cross-sectional area: approximately 21.1 mm²
- Diameter konduktor: about 5.2 mm
- Typical ampacity: 85–95 A (depending on insulation and installation conditions)
This size is commonly applied in both low voltage and medium voltage systems with different structural designs.
