Questions: In accordance with the minimum requirements of the NEC for a dwelling unit, what is the minimum wall space that will require a general-purpose wall receptacle? a. 12 inches b. 2 feet c. 6 feet d. 12 feet

The answer is (b): 2 feet.

Explanation for each option:

a. 12 inches: This is incorrect. According to the National Electrical Code (NEC), a wall space of 12 inches does not require a general-purpose wall receptacle.

b. 2 feet: This is correct. The NEC specifies that any wall space 2 feet (24 inches) or wider must have a general-purpose wall receptacle.

c. 6 feet: This is incorrect. While the NEC does have a rule that receptacles must be placed so that no point along the floor line in any wall space is more than 6 feet from a receptacle outlet, this does not pertain to the minimum wall space requiring a receptacle.

d. 12 feet: This is incorrect. The 12-foot rule pertains to the maximum spacing between receptacles along a wall, not the minimum wall space requiring a receptacle.

Summary: In accordance with the minimum requirements of the NEC for a dwelling unit, the minimum wall space that will require a general-purpose wall receptacle is 2 feet.
