What will happen if you install a 15 amp SC fuse in a 30 amp fuseholder?

Installing a 15 amp SC fuse in a 30 amp fuseholder will not create a secure or appropriate fit. Fuseholders are designed to accommodate fuses of a specific size and electrical rating. A 30 amp fuseholder is structurally designed for larger and higher-rated fuses, which means that a smaller 15 amp fuse may not fit properly or could fit loosely. This improper fit can potentially cause connection issues, leading to an unreliable electrical circuit. Proper fitting is crucial for ensuring a safe and effective electrical operation, as loose connections can lead to overheating or electrical failures.

On the other hand, while the other outcomes suggest scenarios that could arise, they do not accurately reflect the situation of fuse fitting. An improper installation can lead to safety risks and performance issues, reinforcing the importance of using the correct size and rating of fuses in their designated holders.
