Understanding Cable Referencing

Cable type referencing is relatively straight forward;

  • Bare cable = CC
  • LSF covered = CCM
  • 2= Number of conductors
  • L= Light Duty 500v
  • H= Heavy Duty 750v
  • 1.5= Cross-sectional area of conductors

So a 2 core, 1.5sqmm, 500v, LSF cable would be CCM2L1.5
