Short circuit blowing fuse or breaker.
To find the circuit's capacity you have to look at the breaker or fuse that protects that circuit. On the handle of the breaker you will see a number. that number is the tripping capacity of that particular breaker. On a glass screw in fuse you will see a coloured disk with a number on it that is the capacity that the fuse can handle before opening the circuit. On cartridge fuses the voltage and amperage rating will be printed on the body of the fuse.
A fuse blows when the current draw of the circuit is greater than the capacity of the fuse.
A short to ground or an overloaded circuit will blow a fuse.
Hopefully it's a fuse.
If your reference to a safety device is a fuse, then if there is a short circuit, the circuit will be de energized by the opening of the fuse.
Short in the wiring, fuse too small for the circuit, circuit overloaded, or short in something plugged into the circuit.
1. That if a short circuit occurs we will get a sign before short circuit will happen or not ? 2. what we can do ? 3. how fuse can get a short circuit ? 4. which wires we have to use from preventing short circuit ?
when the fuse is not working
A fuse blows when there is a short circuit or an overload in the circuit.
check your house circuit box or check the fuse
