I have an overseas project that involves a 10 HP motor (fire pump) on a three phase, 400 volt, 50 hertz system. I am sizing the conductors and OCPD. Table 430.250 does not cover this voltage level. Article 406.1(A) does not give me the freedom to interpolate the tabulated values, but absent any other resolution, that is what I will do. I don’t have access to the motor yet, so I can’t go by the nameplate. Anyone have an information source I can tap?
