Start with the project data
- Choose the supply system and enter values in the displayed units.
- Use manufacturer data for the actual voltage, temperature and installation.
- Calculate, review the assumptions, then record the inputs with your design.
Calculator methods
- FaultChain: breaking capacity, peak current and thermal withstand
- Voltage drop: resistance, reactance and conductor temperature
- Cable sizing: voltage-drop minimum cross-section
- Cable ampacity: verified base rating and correction factors
- Transformer terminal short-circuit current
- Motor protection: current and selection workflow
- Ohm’s law: resistive DC relationships
