It will draw over 18 amps and will blow a 15 amp fuse.
A short to ground or an overloaded circuit will blow a fuse.
no A FRN fuse is a slow blow fuse where an non is a fast blow fuse. In a pinch a slow blow fuse can be use in a fast blow circuit but not the other way around.
Not necessarily. It can blow because the circuit was overloaded and pulling too much current. That would cause the fuse to overheat and blow.
A fuse blows when the current draw of the circuit is greater than the capacity of the fuse.
The fuse will blow when the current draw in the circuit that the fuse is protecting is more than the rating of the fuse. It usually indicates a faulty componet in the circuit or grounded wiring.
That is a short circuit.
There is an overcurrent/short in the circuit.
the circuit breaker will trip or fuse will blow to open the circuit.
short circuit in the circuit
What Causes Any Fuse to "Blow?"The cause is what fuses were invented and are used for:to detect and protect against SHORT CIRCUIT conditions, and /or CIRCUIT OVERLOAD conditions.
Only when they blow. They don't wear out, they only blow when there is a short in that circuit.
Too much amperage in the circuit. Find what is causing the increase in voltage.
