Hi Charlie. Can a 15A rated receptacle be installed on a 20A circuit? If so please explain why this would be permitted? Thanks in advance for your input, William Turner
Hello William, and thank you for participating. Section 210.21(B)(3) provides guidance on this topic. Where there are two (2) or more receptacle connected to a branch circuit, the receptacle ratings listed in Table 210.21(B)(3) can be used. Installing 15A rated receptacles on a 20A rated branch circuit would be permitted. The blade configuration of a 15A rated receptacle will only allow for 15A or less loads to be plugged in, so no one (1) receptacle can be overloaded, even if connected to a 20A rated branch circuit.
