}Wire size calculator
Minimum conductor size for a circuit: NEC Table 310.16 ampacity at the termination temperature rating, the 240.4(D) small-conductor limits, voltage drop over the run, and the Table 250.122 equipment grounding conductor, increased in proportion under 250.122(B) when voltage drop upsizes the conductors.

Voltage drop for a given conductor size, current and one-way length, single- or three-phase, from NEC Chapter 9 Table 8 circular mils (VD = 2·K·I·L / CM, or √3 for three-phase).

Ohm's law and power: give exactly two of voltage, current, resistance and power; the other two are calculated.
iprvPanel schedule generator
Lays circuits out on a 120/240 V single-phase or 208Y/120 V three-phase panel and totals the load per phase with the imbalance.
