- 1List all devices on circuit, sum wattages
- 2Apply the formula using your project measurements
- 3Add required safety factors or waste allowances per code
Worked Examples
Инпут
Lights 300W + outlets 1200W + appliance 1500W
Резултат
Total Load = 3000W on 20A circuit = 25A → overloaded
Common Mistakes to Avoid
- ✕Not applying code-required safety factors or derating
- ✕Forgetting to account for waste and cut losses in material estimates
