Voltage drop is a relationship between circuit length, current, conductor resistance and system voltage. A wire-size calculator can screen the arithmetic, but the final selection also depends on the installation and applicable electrical requirements.
Full-load amperes are useful for electrical planning, but a simple calculator should not be treated as a complete motor circuit design. Motor type, voltage, phase, efficiency, power factor, starting current and applicable rules all matter.
Tell us what you are trying to build, what problem you are solving and where the digital part becomes difficult. Martzine is built around that gap. Start with the outcome and the constraint, then work back to the right digital layer.
