machines. See 675.2 for the definition of Center Pivot Irrigation Machine.

675.22 Equivalent Current Ratings. To establish ratings of controllers, disconnecting means, conductors, and the like, for the inherent intermittent duty of center pivot irrigation machines, the determinations in

675.22(A) and (B) shall be used.

(A) Continuous-Current Rating. The equivalent con- tinuous-current rating for the selection of branch-circuit conductors and branch-circuit devices shall be equal to

125 percent of the motor nameplate full-load current
rating of the largest motor plus 60 percent of the sum of
the motor nameplate full-load current ratings of all
remaining motors on the circuit.

(B) Locked-Rotor Current. The equivalent locked-rotor current rating shall be equal to the numerical sum of two times the locked-rotor current of the largest motor plus 80 percent of the sum of the motor nameplate full- load current ratings of all the remaining motors on the circuit.
