AC Cable Requirements for Connections to the Utility Grid


  • Conductor type: copper wire

  • Permissible temperature: at least 90°C (194°F)

  • The conductors must be solid or stranded wire.

  • Conductor cross-section: 10 mm² to 16 mm² (6 AWG to 4 AWG)

  • Insulation stripping length: 18 mm (0.7 in)

  • The conductors with regards to their ampacity, rated temperatures, operating conditions and power loss must be made in accordance with the local standards and the National Electrical Code® ANSI/NFPA 70. If the manufacturer (SMA Solar Technology AG) requires a higher conductor cross-section than the standard, the range of the manufacturer must be observed.
