According to the NEC®, how many receptacles are required in a 63-foot long office building hallway?

In a 63-foot long office building hallway, the requirement for receptacles is based on the National Electrical Code (NEC) which outlines specific guidelines for outlet placement. According to NEC, for hallways that are longer than 10 feet, at least one receptacle should be installed for every 100 feet or fraction thereof, but this is generally applicable to hallways adjusted appropriately for their use and code specifics.

In this scenario, since the hallway is only 63 feet long, it does not meet the threshold that requires a receptacle to be installed. Therefore, the determination that no receptacles are required in this specific instance aligns with the NEC provisions for this length, emphasizing that hallways shorter than 100 feet do not necessitate receptacle installations unless specified by different local codes. This context clarifies why the correct answer indicates that no receptacles are necessary for a hallway of this length.
