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 over the run, and the Table 250.122 equipment grounding conductor, increased in proportion under 250.122(B) when voltage drop upsizes the conductor |
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 = 2·K·I·L / CM, or √3 for three-phase). |
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 for the largest conductor. |
load_calculator | Dwelling service load by the NEC 220.82 optional method: 3 VA/ft² lighting, small-appliance and laundry circuits, fixed appliances, demand factor, heating or cooling, and the minimum standard service size. Leave an appliance out to count it as 0 VA. |
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. |
bid_calculator | Electrical bid price from materials, markup, labor hours and rate, job costs, overhead and a target net margin (price = break-even / (1 − margin)). |
nec_ampacity | Allowable ampacity of one insulated conductor from NEC Table 310.16 (not more than three current-carrying conductors in a raceway or cable, 30°C ambient), before any adjustment or correction factors and before the 240.4(D) small-conductor limits. |
