ElectricalElectrical Code Compliance2MildEngineer
An electrical engineer needs a reliable method to calculate phase currents for a balanced three-phase resistive load with single-phase heaters connected line-to-line.
No dedicated tool exists for calculating per-phase full load amps from a known set of line-to-line connected resistive heaters; manual calculation or forum help is required.

App Concept
PhaseCalc Pro
A web and mobile app that automates current calculation for three-phase resistive loads with line-to-line connected elements. Enter heater quantities and specs, and get per-phase amps, total power, and feeder sizing instantly. Saves time and reduces manual calculation errors.
Key Features
- Input heater count, voltage, wattage, and connection scheme
- Auto-balance across three phases
- Output per-phase full load amps, total kW, and recommended feeder size
- Export calculation report for documentation
Target Users: Electrical engineers, technicians, and maintenance personnel in industrial/manufacturing settings dealing with three-phase resistive heating equipment.
Revenue Model: Freemium: free for up to 5 heaters; $9.99/mo for unlimited use and export features; $99.99 one-time for desktop version.
