Question
In the following circuit, the fuse connected will protect the following load(s), if all three loads are current rated 10A and fuse is current rated for 10.5 A
- The fuse will protect load A only
- The fuse will protect load B only
- The fuse will protect C only
- The fuse will protect both load B and load C
Hint:
- Fuse will protect B and C
The correct answer is: The fuse will protect both load B and load C
- The fuse will protect both load B and load C if all three loads are current rated 10A and fuse is current rated for 10.5 A.
- Fuse is connected to neutral wire.
