A hallway in a dwelling is 17 feet long. At least ___ receptacle(s) are required to be installed.

• A. 2 total (one on each wall)
• B. 1 total (one on either wall)
• C. 4 total (two on each wall)
• D. 2 total (both on the same wall)

Answer: (B)

The key idea is how many receptacle outlets are required in a dwelling hallway based on its length. In dwelling units, a receptacle outlet is required in hallways that are 10 feet or longer. A hallway that is 17 feet long meets this threshold, so at least one receptacle outlet must be installed. The outlet can be on either wall, so placing a single receptacle on one wall satisfies the requirement. Having more outlets (two, four, or both on the same wall) would exceed the minimum and isn’t required by this rule for a hallway of this length.
