Cable Size Calculation

Can you get someone to calculate the size of PVC/SWA that I would need:-

need to carry 400A in three separate runs

  1. 70M in Ladder Rack overhead
  2. 75M in Duct underground
  3. 95M in Duct underground 

Are you able to help with advising the sizes of BS5467 they should use?

You can use the sizing application at myCableEngineering.com to size your cables.

If you register, you get some free credits, which should be enough to size your three cables.
