Selection of main and branch circuit breakers
Spreadsheet calculates the following:
- Size and type of main MCCB, RCCB and ELCB for continious and non-continious load
- Sensitivity of MCCB, RCCB and ELCB
- Size of cable
- Size and type of sub-circuit MCCB and MCB for continious and non-continious load
- Total load
- Main and branch circuit current.

I would like to know how the cable selection works because, for example, for a motor load current of 180.4 Amp, and selecting a 2.5 mm2 cable in the drop-down cell, it is indicated that this cable size is OK (green color ) with a maximum length of 8 meters
it is impossible that this size of cable can support this load
For all the above, I would like to know if I am misusing this spreadsheet
Best regards, thank you in advance and I look forward to your response.
