#4. Intermittent operation of electrical equipment in which the load conditions are regularly recurrent is called
CORRECT ANSWER INFO:
Correct answer is C: periodic duty
NEC DEFINITION:
Duty, Periodic: Intermittent operation in which the load conditions are regularly recurrent.
(Article 100 Definitions: Part I General)
NT NOTE:
For the sake of study convenience we list the NEC definitions for types of duty as applied to the cycling of electrical loads:
Duty, Continuous: Operation at a substantially constant load for an indefinitely long time.
Duty, Intermittent: Operation for alternate intervals of (1), load and no load; or (2) load and rest; or (3) load, no load, and rest.
Duty, Periodic: Intermittent operation in which the load conditions are regularly recurrent.
Duty, Short-Time: Operation at a substantially constant load for a short and definite, specified time.
Duty, Varying: Operation at loads, and for intervals of time, both of which may be subject to wide variation.
For the new apprentice electrician and even experienced ones, all this can seem confusing but keep in mind the NEC is for all electricians in different capacities of work. An industrial electrician or one that is part of a facilities management team will understand these terms as they apply to their job more than say an electrician performing residential or commercial construction and service work.
