Do you have a more specific question?
RE: rated current?
RE: rated current?
There are typically two distinct approaches used for designing electrical equipment and for engineering application. In the first case theoretical calculation are usually supported by prototype and production tests in compliance with standards. In the second case, system studies, calculation and engineering judgment are conducted to select the appropriate equipment to withstand the system electrical and mechanical stresses.
Typical calculations are continuous ampacity, short circuit, load flow, insulation coordination, etc.
Some of those factors are ambient temperature, altitude, pollution level, seismic, frequency, voltage, BIL, loading, grounding, etc.

PS: Before getting involved with learning a software, try to understand the technical principle first. Doing the opposite, you be a risk to know how to operate mechanically the software without understanding what you are doing.
