ElectroCalc Pro — a professional electrical calculator for designers, installers and private electricians. All calculations comply with current standards: PUE, GOST, IEC, NEC, BS 7671.
Unlike most online calculators, we correctly account for the circuit breaker non-tripping zone (1.25× current margin) and temperature corrections per PUE 1.3.3. More details in the methodology.
The project is completely free. No paid features, no registration. Supported by affiliate links to equipment (commission does not affect the price for the buyer).
