Importance
When designing an electrical installation fuses and circuit breakers must be chosen so that they can safely break the current of a short circuit. When a large electric current is interrupted an arc forms, and if the breaking capacity of a fuse or circuit breaker is exceeded, it will not extinguish the arc. Current will continue, resulting in damage to equipment, fire or explosion.
