AC cable requirements

  • Conductor type: copper wire

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

  • Outer diameter: 14 mm to 25 mm

  • Conductor cross-section PE: 2.5 mm² to 10 mm² (rigid) / 2.5 mm² to 6 mm² (flexible).

  • Conductor cross-section of line conductor and neutral conductor: 2.5 mm² to 10 mm² (rigid) / 2.5 mm² to 6 mm² (flexible).

  • Insulation stripping length: 18 mm to 20 mm

  • Sheath stripping length: about 100 mm

  • The cable must be dimensioned in accordance with the local and national directives for the dimensioning of cables. The requirements for the minimum conductor cross-section derive from these directives. Examples of factors influencing cable dimensioning are: nominal AC current, type of cable, routing method, cable bundling, ambient temperature and maximum desired line losses (for calculation of line losses, see the design software "Sunny Design" from software version 2.0 at www.SMA-Solar.com).
