Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
• Projects (Pro): keep related calculations together — e.g. motor current → cable → breaker — and export the whole project as a single PDF.
• 5 new calculators: Power Factor (free), PF Correction, Transformer Rating, Short-Circuit Current and Earth Fault Loop (Pro).
• More one-tap links between calculators: kW ↔ A and Motor Current → Cable Sizing → Voltage Drop / Earth Fault Loop.
