It is the basis for:</p> <ul> <li><strong>Cable sizing</strong>: Cables must carry FLA continuously</li> <li><strong>Circuit breaker selection</strong>: MCB/MCCB rated at 125–160% of FLA</li> <li><strong>Overload relay setting</strong>: Set to 100–105% of FLA</li> <li><strong>Starter sizing</strong>: DOL, Star-Delta, VFD selection based on FLA</li> </ul> <h2 id="formula--3-phase-motor">Formula — 3-Phase Motor</h2> <p><strong>I (A) = P (kW) × 1000 / (√3 × V × PF × η)</strong></p>
