wire_size — 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 — 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 =

watts_to_amps — Current drawn by a load in watts at a voltage and power factor, single- or three-phase, plus the 125% continuous-load value.

conduit_fill — Percent fill and maximum number of THHN/THWN-2 conductors of one size in EMT or PVC Schedule 40, from NEC Chapter 9 Tables 1, 4 and 5.

box_fill — Minimum outlet box volume from NEC 314.16(B): conductor, device (2 each), clamp and grounding allowances times the Table 314.16(B) volume fo

load_calculator — Dwelling service load by the NEC 220.82 optional method: 3 VA/ft² lighting, small-appliance and laundry circuits, fixed appliances, demand f

ohms_law — Ohm's law and power: give exactly two of voltage, current, resistance and power; the other two are calculated.

panel_schedule — 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.
