Electrical Power Calculator
Calculate electrical power parameters, load requirements, cable sizing, and energy consumption with our comprehensive calculator. Optimize your electrical system design for safety and efficiency.
Step 1: Load Specifications
8 hours
Standard Electrical Parameters
Residential: 230V single-phase. Industrial: 400V three-phase. Power factor typically 0.8-0.95. Current ratings depend on cable size and protection devices.
Step 2: System Specifications
30°C
Cable Sizing Guidelines
Maximum voltage drop: 3% for lighting, 5% for other circuits. Consider ambient temperature derating factors. Always consult local electrical codes and regulations.
