Maximum Available Fault Current... What is it? - Rozel | Arc flash ... Going back to electricity we can look at a specific example. Consider a GE brand, TEY style, 100 amp breaker that feeds equipment named "PANEL X". This breaker is rated to a maximum 14,000 amp fault current. If PANEL X pulls more current than 100 amp, eventually the TEY breaker will trip. The interrupting rating must be sufficient for the maximum possible fault current available on the line-side terminals of the equipment [110.9]. You'll find the standard ratings for fuses and fixed-trip circuit breakers in 240.6. An OCPD protects equipment by opening when it detects a short circuit or ground fault.
