## Tools (as reported by the server, not verified)

- `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.
