NEC applies primarily to branch circuits and to feeders, which are, by 
definition, internal to a premises, but external to an equipment. 
(Electric utilities are exempt).

NEC does NOT apply to internal wiring of a manufactured product. (UL may 
apply to consumer apparatus, but NOT to so-called "professional" 
equipment. NEC also has exemptions for so-called "professional" 
equipment. "Professional" equipment is presumend to be operated by a 
skilled person).

One manufacturer I am quite familiar with has ALWAYS employed black wire 
within its units. The ends are numbered at the terminals, and in some 
cases those numbers may be printed along the length of the wire.

The black, red, white, green convention really only applies to the very 
first connection point to the equipment, which may be a fusible safety 
switch, or a hard-wired terminal block.
