Minimum wiring space and wire bending space requirements are specified for field installed wires terminating in or passing through enclosures or terminal boxes.
The requirements are considered to be the minima that would permit field wiring without damage to the wires.
This Standard shall form a part of and be read in conjunction with all individual standards to which the requirements of this Standard may apply, except that, where an individual standard contains requirements that are at variance with those of this Standard, the requirements of the individual standard shall take precedence.
