It takes into account 430.52(C)(1) Exception No. 1, which allows the next standard amp rating fuse (per standard fuse amp ratings in 240.6) to be used if the maximum percentage in Table 430.52 does not correspond to a standard fuse amp rating.

NEC 430.224 Size of Conductors: “Conductors supplying motors shall have an ampacity not less than the current at which the motor overload protective device(s) is selected to trip.” Using a suitable table from art.310.60 Tb.60-85 for 209 A we’ll get 1/0 to 3/0 copper.

Step 3 - Table 430-152 - Motors shall have a rating or setting of motor branch-circuit short-circuit and ground- fault protective devices capable of carrying the motors inrush currents at startup. 430-152 is the maximum allowable ratings of these devices. The motor rated currents are based on standard 1500 RPM motors with normal cooling design. To select the proper sized Soft Start Control or Solid State Starter, check motor the KW rating and voltage rating for motor FLA. Use tables 430.247 thru 430.250 to determine the motor FLC. (Note we do not use the motor nameplate information). From table 430.52 we find the correct maximum setting value for standard short-circuit protection; We multiply the motor FLC by the value in table 430.52; We round up the nearest standard rating available, found in Table 240.6(A). The control is unable to properly detect motor speed and the machine will shut down. If a failure occurs during high-speed spin, the door will be unlocked after 3 minutes. Check wire harness connections between the Drive Motor/Tachometer and the Motor Control Unit (MCU), and between the MCU and the Central Control Unit (CCU) Check the Drive Motor

NEC Article 300.19 and NEC Table 300.19(A) provide specifics on conductor and raceway supports. NEC Article 300.20 requires conductors to be grouped together to reduce heating (this takes advantage of magnetic field Find the motor FLC using the NEC FLC Tables [430.6(A)(1)]. The highest rated motor is based on the motor with the highest full-load current [430.17]. The “other motors in the group” value (on the same line) is determined by balancing the motors’ FLCs on the feeder being sized, then selecting the line that has the highest rated motor.

In the 2011 NEC, a simple table existed showing the service size on the left and the minimum size conductor required to supply the service on the right. To use the table, one would first determine the minimum size service or feeder by using the load calculations in Article 220 and then select the minimum size conductor from Table 310.15(B)(7).
