Question
The fuse current rating should be chosen such that
- It is exactly equal to the current rating of electrical the appliance
- It is less to the current rating of electrical the appliance
- It is greater equal to the current rating of the electrical appliance
- It is just above the current rating of the electrical appliance
Hint:
Just above corrent rating
The correct answer is: It is just above the current rating of the electrical appliance
- The fuse current rating should be chosen such that it is just above the current rating of the electrical appliance.
- Voltage rating of the fuse must always higher than the voltage rating of the circuit that it is protecting.
