How do you calculate fusing factor?

The fusing factor is calculated by dividing the actual current required to fuse a conductor by the rated current of the conductor. It can be expressed as:

[ \text{Fusing Factor} = \frac{\text{Actual Fusing Current}}{\text{Rated Current}} ]

This factor helps determine the safety and performance of fuses in electrical systems, ensuring they operate effectively under overload conditions. A fusing factor greater than 1 indicates that the fuse is capable of handling more current than its rated value.
