Prospective Short Circuit Current
The prospective short circuit current (PSCC) is the highest electric current which can exist in a particular electrical system under short-circuit conditions. It is determined by the voltage and impedance of the supply system. It is of the order of a few thousand amperes for a standard domestic mains electrical installation, but may be as low as a few milliamperes in a SELV (Safety Extra Low Voltage or, occasionally, Separated Extra Low Voltage) system or as high as hundreds of thousands of amps in large industrial power systems.

“You shall love peace as a means to new wars—and the short peace more than the long one.”
—Friedrich Nietzsche (1844–1900)
“Within the circuit of this plodding life
There enter moments of an azure hue,
Untarnished fair as is the violet
