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 mekanikal, and installation flexibility.
Key parameters of 4 AWG cable:
- Cross-sectional area: approximately 21.1 mm²
- Conductor diameter: 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.
