ElectricalEngineeringCalcsKit

This app is a comprehensive electrical engineering calculator suite built on NEC 2023, designed for licensed electricians, electrical engineers, and advanced students who need fast, accurate code-compliant calculations in the field or at the desk. This app includes 15 purpose-built calculators spanning voltage drop, wire ampacity with derating, conduit fill, breaker and fuse sizing, grounding conductors, Ohm's law, power factor correction with capacitor sizing, energy consumption and cost estimation, lighting design via Zonal Cavity Method, motor protection per Article 430, transformer sizing, generator sizing, panelboard load calculations, short-circuit available fault current, and a full electrical unit converter. What sets this app apart is its integrated NEC Quick Reference Library — a searchable, offline-ready database of NEC 2023 wire ampacity tables (copper and aluminum at all temperature ratings), motor full-load current tables for both single-phase and three-phase, conduit fill internal areas for EMT/IMC/RMC, standard OCPD sizes per 240.6, and equipment grounding conductor sizes per Table 250.122. No flipping through codebooks — everything is at your fingertips. Additional features include a Favorites system for one-tap access to your most-used calculators, a persistent calculation history with full input/output records, share and export capability for sending calculation reports to colleagues, and a built-in electrical unit converter covering AWG-to-metric, HP-to-kW, temperature, length, and energy conversions. Every calculation displays the applicable NEC article reference, provides pass/fail compliance indicators, and can be saved to history or copied to clipboard instantly.
