Calculator | Short Circuit Current

A short circuit current calculator must account for different fault types, each producing different magnitudes. In order of decreasing typical magnitude:

A bolted fault assumes zero arc impedance. Real faults have arc resistance, which reduces current. However, safety standards require bolted fault for equipment rating. short circuit current calculator

Most SCCCs default to the because it yields the highest current, but advanced calculators allow selection of fault type. A short circuit current calculator must account for

Thus, the SCCC provides the fundamental input for safety, reliability, and code compliance (e.g., NEC® Article 110.9, 110.10, and 240.86). which reduces current. However
