Final answer:
The NEC does permit the sizing of branch circuit conductors for a range to be less than the nameplate rating, under specific conditions to ensure safe operation.
Step-by-step explanation:
The National Electrical Code (NEC) has specific regulations regarding the sizing of branch circuit conductors for a range. The correct answer to the question, 'The NEC _______ the branch circuit conductors for a range to be sized at less than the nameplate rating of the range,' is 'Does Permit.' Therefore, the NEC does allow for the branch circuit conductors to be sized at less than the nameplate rating of the range, under certain conditions. This is to accommodate for the fact that not all elements or burners will typically be used at maximum power simultaneously. However, these conditions should be carefully evaluated according to the provisions stipulated by the NEC to ensure that the conductors are capable of safely carrying the maximum potential load.
