SWA Earthing

 

90°C XPLE steel wire armoured cables

This chart shows which (90°C XPLE) SWA cables comply with Table 54.7 when using only the armour as the CPC:

Green = compliant, Red = Non-Compliant

Notes

  * A cable which does not originally comply can still be brought into compliance with 54.7 providing an adequately sized additional earth cable is run in or a core is doubled up with the armour.
  * If the cable does not comply with table 54.7 it may still be used if it complies with the adiabatic equation.

70°C PVC Thermoplastic steel wire armoured cables



This chart shows which (70ºC thermoplastic) SWA cables comply with Table 54.7 when using only the armour as the  CPC:
