Cable Size Calculation



Cable sizing compiles with BS 7671:2008 (IEE Wiring Regulations Seventeenth Edition) and IEC 60364:2001


Calculation Notes

Cable sizing compiles with:
 - BS 7671:2008
   IEE Wiring Regulations 17th Edition
 - IEC 60364:2001

Help and Tips

Cable size is selected as follows:

  1. Cable is calculated on current capacity
  2. Voltage drop is calculated (and cable size increased if necessary)
  3. Fault level withstand is calculated (and cable size increased if necessary)

Tip: if you don’t want fault level to be considered, you can set it to a very low value.
