Circuit Breaker Sizing ची गणना कशी करावी
Circuit Breaker Sizing म्हणजे काय?
Circuit Breaker Size Calculator helps contractors and tradespeople accurately size, spec, and estimate materials and systems.
सूत्र
Breaker Size = Load Watts / Voltage × 1.25 (125% NEC rule)
चरण-दर-चरण मार्गदर्शक
- 1Calculate total load in watts, divide by voltage, multiply by 1.25
- 2Apply the formula using your project measurements
- 3Add required safety factors or waste allowances per code
Worked Examples
इनपुट
2400W load, 120V circuit
परिणाम
Breaker = 2400/120 × 1.25 = 25A → use 30A breaker
Common Mistakes to Avoid
- ✕Not applying code-required safety factors or derating
- ✕Forgetting to account for waste and cut losses in material estimates
