A
Minimum Fuse Rating
6.25 A
Minimum Fuse Rating vs Operating Current
सूत्र
## Fuse Sizing **Fuse >= I_operating x Safety_Factor** Standard practice: 1.25 (125%) for continuous loads. Round up to next standard fuse value.
हल किया गया उदाहरण
Circuit draws 5 A normally.
- 01Min fuse = 5 x 1.25 = 6.25 A
- 02Use a 7 A or 7.5 A standard fuse.
अक्सर पूछे जाने वाले प्रश्न
What safety factor?
125% for continuous loads per NEC. 110-115% for intermittent loads.
Fast-blow vs slow-blow?
Fast-blow opens instantly. Slow-blow tolerates brief surges for motors/transformers.
Protect wire or device?
Fuse must be rated below wire ampacity to protect wiring.
