Amtech usage

[Indy]

Good afternoon
We have a main lv switchboard that feeds a sub main board ( and other equipment) the sub main board then feeds a panel( and other equipment and panels) which controls various motors.

We are interested in the following main lv section that feeds sub main section and sub main section that feeds the panel.

My question is if I model the the system we are interested in on Amtech would we need to take into consideration the other equipment that the main and sub main lv boards feed to allow for discrimination etc?

If the "other equipment " are motors-synchronous or induction- you have to consider it for short-circuit and grounding fault. If not you take it only for overload protection discrimination.
