Requirements on the AC conductors

  • Conductor type: copper wire

  • The conductors must be solid or fine-stranded. When using fine-stranded wire, bootlace ferrules can be used.

  • Conductor cross-section: 10 mm² to 16 mm² (8 AWG to 6 AWG)

  • Insulation stripping length: 18 mm to 20 mm (0.71 in to 0.79 in)

  • The conductors with regards to its ampacity, rated temperatures, operating conditions and its power loss must be made in accordance with the local standards and the National Electrical Code® ANSI/NFPA 70 or the Canadian Electrical Code® CSA C22.1. If the manufacturer (SMA Solar Technology AG) requires a higher conductor cross-section than the standard, the range of the manufacturer must be observed.
