Dear,
According to the manual, it is necessary for the user to define the specific section. To ensure that your installation complies with safety standards, I recommend making a preliminary calculation of the allowable current, taking into account the grouping, temperature and channeling factors of your installation. As well as a calculation of the voltage drop generated by selectioned conductor. To obtain the factors mentioned above and the resistance and reactance of a conductor, you can use a cable catalog.
Once these calculations have been made, it is essential to identify the minimum stretch that meets both requirements. By assuming this section for the simulation, you can move forward with greater confidence in your simulation ohmic loss calculations.
However, it is important to note that if you go ahead with the project, it is crucial to check the maximum short circuit current to ensure that all safety standards are met.
Greetings,
