Electrical Calculator vs BaseCalc Electric Calculator

Electrical Calculator is a fast, offline toolkit for electricians, students and DIY pros - with no subscription and no ads. The core calculators are free forever. Unlock Pro once (no subscription, ever) for the full professional set. FREE - Ohm's Law: enter any two of volts, amps, ohms, watts - Energy cost: power, hours and rate to kWh and cost - Series and parallel resistance PRO (one-time) - Voltage drop: wire, load and length to drop, percent and end voltage - Wire size: smallest AWG for load and voltage drop - Ampacity: AWG to amps (NEC 310.16, 75C) with breaker limits - Conduit fill: EMT and THHN to percent fill - Box fill: conductors and devices to required volume (NEC 314.16) - Motor FLA: HP and voltage to full-load amps, conductor and breaker - Three-phase power and current, transformer kVA - Power factor correction, conduit bending, wire resistance, amps to kW/HP MORE - Works fully offline, no account, no tracking - Light and dark themes, English and Russian - Paperless tape: save and share your results Estimates are based on the NEC. Always verify against your local code and the authority having jurisdiction. This app is a tool, not a substitute for a licensed electrician.

BaseCalc Electric Calculator is an NEC-aware electrician calculator for job-site field math, worksheets, materials, and saved calculation history. Run voltage drop, wire size, conduit fill, service load, breaker, grounding, EV charger, generator, and other electrical calculator checks on site, then save the result for the job. 18 CALCULATORS FOR DAILY FIELD WORK • Ohm's Law — solve voltage, current, resistance, and power from any two known values. • Voltage Drop — single-phase or three-phase, copper or aluminum, with a 3% target check. • Wire Size — minimum conductor sizing based on NEC 310.16 ampacity with temperature and conductor-count adjustment. • Conduit Fill — fill percentage for EMT, PVC, RMC, IMC, FMC, and LFNC. • Conduit Size — auto-recommend the first raceway size that passes fill. • Box Fill — required box volume per NEC 314.16. • Conduit Bend — fast offset bend mark calculations. • Bend Layout — rolling offsets, 3-point saddles, and 4-point saddle layout guidance. • Service Load — dwelling service/load sizing guide based on NEC 220 concepts. • Breaker + Wire — continuous-load OCPD and conductor guidance. • Grounding — EGC and GEC starting-point sizing. • Motor Circuit — FLC, conductor ampacity, overload, and short-circuit/ground-fault guides. • Pull Box — straight, angle, and U-pull box dimension guide. • Derating — temperature correction and current-carrying conductor adjustment. • EV Charger — branch circuit and service-load check. • Generator — backup generator kW and output-current target. • Transformer — kVA to full-load amperage. • Power — kW, kVA, current, voltage, and power factor relationships. EVERY RESULT IS EXPLAINED • Clear pass/fail or sizing messages. • The governing limit, final answer, and calculation breakdown. • Saved local history so you keep a job-site record. DEVICE-LOCAL FOR THE FIELD • Works offline by default. • No BaseCalc account or cloud sync. • Job contact, worksheet, setting, and calculation data is stored in local app storage, protected by your device security. • There is no BaseCalc cloud option. • Device backups, when available on your operating system, remain under your device-account settings. • Dark and light themes with a high-contrast job-site interface. BaseCalc Electric is a professional reference tool. Always verify against the current National Electrical Code and your local amendments. The authority having jurisdiction has the final say.
