What is the maximum number of 15- and 20-ampere receptacles permitted in a single circuit?

• A. 6
• B. 8
• C. 10
• D. 12

Answer: (B)

The maximum number of 15- and 20-ampere receptacles permitted on a single circuit is determined by the National Electrical Code (NEC). According to NEC guidelines, a general-purpose branch circuit can serve a maximum of 10 receptacles. This allows for a sufficient number of outlets while helping to ensure that the circuit does not become overloaded with devices drawing power. Therefore, having a maximum of 8 receptacles on a single circuit is in line with the intention of providing flexibility for usage while maintaining safety and performance standards. It's important to remember that each receptacle counts toward the allowable limit, and considerations of the load that will be used on the circuit should be taken into account to prevent circuit overloads. Understanding this guideline is essential for following best practices in electrical installation and ensuring compliance with local codes, which typically align with NEC standards.
