Electrical Tools (E‑Tools) is a Windows program that automates 14 common electrical calculation and data look‑up tasks following NEC and IES procedures. It sizes wires based on ampacity and percent voltage drop, sizes conduits, calculates voltage drop across up to five components, performs short‑circuit calculations across up to five nodes, and determines single‑room luminaire requirements. E‑Tools reads and converts IES photometric data files, sizes service entrance panel equipment and motor equipment, sizes power factor correction capacitors, performs current‑to‑power conversions, includes an automatic Ohm’s Law calculator, and provides quick look‑ups for formulas plus conductor resistance and reactance values. The software produces comprehensive, concise reports to document results.
