DuBois Regional Medical Center West Wing Addition Benjamin Ardary - 91 2005 Lighting/Electrical Thesis Fault Current Study Introduction: A Fault Current analysis is probably one of the most crucial calculations of the electrical design process. This analysis allows designers to find the maximum available Fault Current at different points in the electrical system. The Fault Current found is then used to design and specify electrical components that can withstand the tremendous forces of faults without harming occupants and without damaging equipment. These faults are short circuit conditions in which the normal level of Current flow is suddenly increased by a factor of hundreds or even thousands, which is a deadly magnitude. For the purpose of this Study , a critical path was selected in the new addition that started at the utility pole and ended up at a distribution panel that serves branch circuits.
devices, the total impedance, the component short-circuit current ratings, and circuit characteristics shall permit circuit clearing without extensive damage to the electrical components of the circuit.
