Question

It is dangerous to use a fuse higher than the correct rating.

• A. True
• B. False

Answer 1

The correct option is B False

1. Fuse is a safety device that protects electrical circuits from the effects of excessive currents.
2. The fuse needs to be rated slightly higher than the maximum operating current of the protected device so that the fuse won't blow when the equipment is used.
3. Just putting in an over-rated fuse will not cause the circuit to be overloaded.
4. The fuse will not blow out even if the current rises above the permitted value. Such a fuse remains the circuit close and allows the current to flow beyond the limit permitted to the wiring or other components.
5. This leads to damage to the appliances.

Hence, the given statement is false.
