For a 20-amp branch circuit supplying two or more receptacles, which option lists the minimum rating for receptacle devices?

• A. 10 A
• B. 20 A
• C. 25 A
• D. 15 A

Answer: (D)

On a 20-amp branch circuit that serves two or more receptacles, the receptacle devices can be the smaller standard rating. The circuit protection remains at twenty amps, so using a fifteen-amp receptacle is permitted and is the minimum allowed in this setup. A ten-amp receptacle isn’t a standard option for general outlets, a twenty-five-amp receptacle isn’t used for typical residential receptacles, and while a twenty-amp receptacle would work, it isn’t the minimum. If there were only a single receptacle on the circuit, the minimum device rating would be higher.
