Short Circuit DetectionShort Circuits and DetectionShort CircuitsA short circuit is an unwanted current path.A short circuit to ground.A short to ground beforethe electrical load in the circuit will usually blow the fuseprotecting the circuit.A short to ground afterthe electrical load in the circuit will usually cause the electrical loadto turn on and stay on as long as there is power in the circuit.A short circuit power.A short to power beforethe electrical load in the circuit usually will not do anything, there ispower there anyway.A short to power afterthe electrical load in the circuit will usually cause the electrical load toeither:Turn off because of opposing voltages on both sides of the load.Blow the fuse of the circuit that it is shorted to.Short Circuit DetectionCircuit breakerscan be used to replace a blown fuse while attempting to locate a short circuit.Always use the same current rating circuit breaker as the fuse to be replaced. A fuse blows and acircuit breaker will open when there is too high of current (too low of resistance) in the circuit. The
