The NEC does not apply to electric utilites. The NEC makes the basic assumption that you are qualifed to use it and follow its rules:
90.1 (C) Intention. This Code is not intended as a design specification or an instruction manual for untrained persons.
And this is about the only language it has for qualifications:
Qualified Person. One who has skills and knowledge related to the construction and operation of the electrical equipment and installations and has received safety training to recognize and avoid the hazards involved.
FPN: Refer to NFPA 70E?-2004, Standard for Electrical Safety in the Workplace, for electrical safety training requirements.
So for example I am a master electrician but am qualifed to work on equipment over 600 volts.
