If this loop has too much resistance (impedance), the fault current will be too low to trip the breaker quickly, leaving the metal casing live and dangerous. Args: cables: List of cable segments in the
The prospective short-circuit current (Isc) can be calculated using Ohm's law: fault loop calculator
