It just calculates the voltage drop consult the above table for rules of thumb or your local or national electrical code or your electrician to decide what is legal. The following table of wire sizes does not show any sizes bigger than 4 0 gauge because solid copper wire becomes impractical to handle at those sizes. Awg general rules of thumb for every 6 gauge decrease the wire diameter doubles and for every 3 gauge decrease the cross sectional area doubles.
