You are working as a plant electrician. It is your job to install a 300-hp three phase squirrel-cage induction motor. The supply voltage is 480 V. The power company has determined that the maximum amount of starting current that can be permitted by any motor in the plant is 3000 A. The motor nameplate is as follows: Will it be possible to start this motor across the line, or will it be necessary to use a reduced-voltage starter to reduce starting current?   Phase: 3           FLA: 352 Volts: 480       RPM: 1755 Frame:   Code: L
