Electrical Calculator ElecCalc

Solve electrical calculations faster on site or in the office. ElecCalc gives engineers, electricians, technicians, and students 15 focused tools for wire sizing, voltage drop, breakers, transformers, grounding, motors, power factor, and more.

WHY ELECCALC • Electrical calculator toolkit built for field and office work • Wire size, voltage drop, cable ampacity, breaker, transformer, and grounding tools • IEC-based assumptions shown clearly with risk-sensitive results • Calculation history, favorites, and formula reference for repeated work • Clean interface designed for fast checks, not bloated spreadsheets

CALCULATORS INCLUDED • Ohm's Law for voltage, current, resistance, and power • Power calculator for active, reactive, apparent power, and power factor • Cable section and voltage drop calculations • Cable ampacity based on IEC 60364-5-52 installation methods • Breaker and fuse selection with overload protection checks • Transformer loading, losses, efficiency, and short-circuit current • Motor current, starting current, torque, and IEC 60034-30-1 efficiency • Grounding, compensation, lighting, energy consumption, unit conversion, and formulas

Use ElecCalc when you need a quick engineering estimate, a repeatable calculation flow, or a compact reference while working away from your desk.
