See Section [/quote]430.10 Wiring Space in Enclosures.
(A) General. Enclosures for motor controllers and disconnecting means shall not be used as junction boxes, auxiliary gutters, or raceways for conductors feeding through or tapping off to the other apparatus unless designs are employed that provide adequate space for this purpose.
FPN: See 312.8 for switch and overcurrent-device enclosures.[quote]
PS: The word adequate is vague and undefined and is not supposed to be used in the NEC according to the Manual of Style available from NFPA as a download.
