Calculations第 13 / 110 题
From the motor full-load current table, what is the full-load current of a 25-HP, 480-V, three-phase induction motor?
a.34 A
b.40 A
c.28 A
d.42 A
解析
The table value for a 25-HP, 460-480-V three-phase motor is 34 A. Table full-load current (FLC), not nameplate, is used for conductor and protection sizing.
