Important Disclaimer

This tool provides engineering estimates based on international standards: IEC 60204-1 (Safety of machinery), IEC 60364-4-43 (Overcurrent protection), IEC 60364-5-52 (Cable sizing), ISO 1217 (Compressor testing), and ISO 4414 (Pneumatic systems). Always consult a certified engineer for site-specific installations as per local codes.

  • IEC 60204-1 Compliance: Motor circuit protection calculated per clause 7.2 (Overload protection) and clause 8 (Wiring practices).
  • IEC 60364-5-52 Compliance: Cable sizing includes correction factors per Table 52.14-52.15 for ambient temperature, grouping, and installation method.
  • IEC 60364-4-43 Compliance: Overcurrent protection per clause 433 (Protection against overload current) for motor circuits.
  • Cable sizing based on PVC insulated copper conductors, installation method B2 (in conduit on wall), 3 cables in bundle, 30m cable length.
  • Voltage drop limited to 5% per IEC 60364-5-52 clause 525 for motor circuits.

Note: National Electrical Code (NEC) requirements may differ for US installations. Always verify with local authorities having jurisdiction.
