⚡ KEY CALCULATORS & FEATURES

• Cable Sizing & Voltage Drop
Calculate exact cable cross-sectional area and voltage drop percentage for single-phase and three-phase systems based on load current, length, and conductor type.

• Solar PV & Battery Storage Sizing
Design complete solar power systems. Compute required PV array capacity (kWp), inverter rating, and battery bank capacity (Ah/kWh) based on daily energy demand and peak sun hours.

• Circuit Breaker & Busbar Capacity
Determine optimal circuit breaker ratings (MCB, MCCB, ACB) and continuous busbar current-carrying capacities with thermal and ambient correction factors.

• Motor & Generator Sizing
Calculate full-load current (FLA), starting current, power factor, efficiency, and generator kVA sizing for single-phase and three-phase induction motors.

• Transformer & Short Circuit Analysis
Compute transformer full-load currents, primary/secondary turns ratios, and prospective short-circuit currents (kA) at distribution points.

• Power Factor Correction
Determine the exact capacitor bank rating (kVAR) required to improve power factor and avoid utility penalties.

• Earthing Resistance & Conduit Sizing
Calculate grounding electrode resistance and optimal electrical conduit fill ratios for safe cable routing.

• Resistor Color Code & Unit Converter
Instantly decode 4, 5, and 6-band resistors, and convert units across power, voltage, current, resistance, energy, and length.
