Eddy current inspection is one of several NDT methods that use the principal of “electromagnetism” as the basis for conducting examinations. .. Eddy currents are created through a process called electromagnetic induction. When alternating current is applied to the conductor, such as copper wire, a magnetic field develops in and around the conductor. This magnetic field expands as the alternating current rises to maximum and collapses as the current is reduced to zero. If another electrical conductor is brought into the close proximity to this changing magnetic field, current will be induced in this second conductor. Eddy currents are induced electrical currents that flow in a circular path. They get their name from “eddies” that are formed when a liquid or gas flows in a circular path around obstacles when conditions are right..

Ch. 6,7: Faults and Fault Calculations. Short-circuit . current rating (SCCR) of industrial control panels . Introduction . Article 409 on Industrial Control Panels was added to the NEC in its 2005 edition. This Article requires all Industrial Control Panels to be marked with a short-circuit current rating. The short-circuit current rating (SCCR) requirements for UL 508A came into force in April 2006. These changes impact control panel builders, OEMs and end users in a number of different ways: .
