- 2Apply the formula using your project measurements
- 3Add required safety factors or waste allowances per code
Çözümlü Örnekler
Giriş
480V, 100A, three-phase
Sonuç
kVA = (480×100×1.732)/1000 = 83.1 → use 100 kVA
Kaçınılması Gereken Yaygın Hatalar
- ✕Not applying code-required safety factors or derating
- ✕Forgetting to account for waste and cut losses in material estimates
