VoltCalc Live

VoltCalc: Electrical Calculator A practical electrical calculator for electricians, electrical contractors, apprentices, technicians, and electrical professionals in the United States and Canada. VoltCalc brings essential electrical calculations into one fast, easy-to-use tool designed for field work and offline use. KEY ELECTRICAL CALCULATORS • Voltage Drop Calculator Calculate voltage drop, voltage at the load, and voltage drop percentage for supported electrical systems. • Wire Size & Ampacity Calculator Work with conductor size, copper or aluminum conductors, temperature ratings, and ampacity calculations. • Electrical Load Calculator Add loads and calculate total VA, watts, and current for selected voltage systems. • Conduit Fill Calculator Calculate conductor fill and determine an appropriate conduit size for supported conduit types. • Motor FLC Calculator Calculate motor full-load current for supported motor configurations. • Breaker & OCPD Calculator Perform breaker and overcurrent protection calculations using the selected inputs and application. • Ohm's Law Calculator Calculate voltage, current, resistance, and power from known electrical values. • Power Calculator Calculate watts, kilowatts, VA, and kVA for supported single-phase and three-phase systems. BUILT FOR ELECTRICIANS VoltCalc is designed as a digital electrical toolbox, not just a collection of disconnected calculators. Save calculations and return to them later. Organize work into projects. Move between related calculations without repeatedly entering the same values. Example workflow: Motor FLC → Wire Size → Voltage Drop → Breaker → Conduit Fill OFFLINE-FIRST Core calculations are designed to work without an internet connection. No account is required for the core calculator experience. Use VoltCalc on job sites, service calls, workshops, and other locations where connectivity may be limited. SAVE & ORGANIZE YOUR WORK Create projects and keep related calculations together, including: • Residential circuits • Workshop circuits • HVAC electrical loads • Panels and feeders • Motor circuits • Conduit calculations • Voltage drop calculations Open, edit, duplicate, save, and share supported calculations. NORTH AMERICAN FOCUS VoltCalc is designed for electrical work in the United States and Canada, using common North American electrical units and workflows. The app is designed with versioned standards data so supported electrical code editions and jurisdiction-specific rules can be maintained separately from the calculation engine. Always verify the applicable electrical code, local amendments, installation requirements, equipment ratings, and manufacturer specifications for your project. FIELD-FRIENDLY DESIGN • Fast input • Clear calculation results • Large, readable values • Practical unit selection • Calculation history • Saved projects • Dark mode • Offline-first operation • Shareable results • PDF reports for supported calculations PROFESSIONAL REFERENCE TOOL VoltCalc is a calculation and reference utility. It does not replace applicable electrical codes, licensed electrical professionals, engineering judgment, inspections, or manufacturer requirements. Results should be independently verified before installation or use on a project. PREMIUM VoltCalc offers a one-time lifetime purchase for available premium features.
