If the current jumps through the air, it creates an arc flash —an explosion of plasma that reaches temperatures hotter than the surface of the sun. How to Calculate Short-Circuit Current
In large buildings, engineers use "selective coordination." This ensures that if a short circuit happens in a specific office, only the breaker for that office trips. The main breaker for the whole building stays on, preventing a total blackout. short-circuit current
