How often must a receptacle outlet be located in a dwelling unit according to NEC requirements?

• A. Every 6 feet along walls
• B. Every 12 feet along walls
• C. Every 15 feet along walls
• D. Every 10 feet along walls

Answer: (B)

The National Electrical Code (NEC) specifies that receptacle outlets in dwelling units must be installed at intervals not exceeding 12 feet along walls. This requirement is intended to ensure that there are sufficient receptacles available for the safe and convenient use of electrical devices, reducing the need for extension cords and minimizing the risk of electrical hazards. By placing receptacles every 12 feet, the code helps to address common scenarios where furniture and appliances are typically located, making it easier for homeowners to access power without overloading circuits or creating tripping hazards. This spacing allows for adequate coverage in living spaces, such as living rooms and bedrooms, where electrical devices are frequently used. In contrast, the other options suggest distances that do not align with the NEC guidelines. Choosing any of those incorrect intervals may lead to insufficient electrical access in certain areas, potentially creating safety concerns.
