How do I choose between DC/single-phase and three-phase AC calculations?

Select DC/single-phase for batteries, solar panels, or simple 24V circuits; choose three-phase AC for industrial motors or larger equipment powered by three-phase electricity.

What does the allowable voltage drop setting do?

It defines the maximum percentage of voltage loss allowed between the source and the load; lower values require larger wire sizes to maintain efficiency.

Can this calculator determine AWG size directly?

Yes, the tool outputs the wire cross-sectional area, diameter, and the equivalent American Wire Gauge (AWG) for the calculated dimensions.

Is the result affected by the conductor material selected?

Yes, resistivity values differ between copper and aluminum; choosing the material ensures the calculated wire size accounts for the specific conductor's resistance.
