"All conductors of the same circuit and, where used, the neutral and all
equipment grounding conductors shall be contained within the same raceway,
cable tray, trench, cable, or cord." [Article 300-3(b)]
"Single conductors ... shall only be permitted to be installed where part of a
recognized wiring method of Chapter 3." [Art. 300-3(a)]
The only methods recognized by Chapter 3 which use single conductors are "open
wiring on insulators" and "concealed knob and tube". The former is permitted
only in agricultural and industrial installations, and the latter is permitted
only as an extension of an existing system (not as a new installation).
