On a 20-amp branch circuit that serves two or more receptacle outlets, which statement is true about receptacle device ratings?

• A. 10 A devices are always required
• B. 20 A devices are not allowed
• C. 25 A devices are preferred
• D. 15 A devices are the minimum permitted

Answer: (D)

On a 20-amp branch circuit that serves two or more receptacles, the outlets must be rated to handle at least 15 amps. You can use 15-amp or 20-amp receptacles, but you cannot use undersized 10-amp devices or nonstandard 25-amp devices. Therefore, 15-amp receptacles are the minimum permitted, which is why that statement is correct.
