  • Magnetic particle inspection Wikipedia

    Magnetic particle Inspection (MPI) is a non-destructive testing (NDT) process for detecting surface and shallow subsurface discontinuities in ferromagnetic materials such as iron, nickel, cobalt, and some of their alloys.The process puts a magnetic field into the part. The piece can be magnetized by direct or indirect magnetization. Direct magnetization occurs when the electric current is

    A 300A dev is acceptable; a 100%-rated dev is not needed since the load is noncontinuous. Example 3: 200A continuous load. OCPD = 100% noncontinuous load + 125% continuous load = (1.00 x 0A) + (1.25 x 200A) = 250A. Therefore, a 250A dev is needed. If a 100%-rated CB is selected, a 200A rating is permitted.
