) of a 13.8 kV MV switchgear feeders in APR 1400 is ranged from about 30 to 450 A. That means the accuracy class can be C20 to C200 according to Table 1, if a motor load of 13.8 kV switchgear is 1,500 hp and rated current is 49 A, a 50:5 CT or 75:5 CT is applicable in terms of CT ratio. In addition, the CT rated thermal short-circuit
