So the 15/20 amp circuits are confusing, from my reading you can have a 20 amp breaker with 12g wire and multiple 15 amp receptacles because the total draw of all receptacles combined might exceed 15 amps.
However, you can't have a single 15 amp outlet on a 20 amp circuit, because then the outlet might overheat if it draws more than 15 amps instead of the breaker tripping. For the purposes of this, a duplex receptacle is considered two separate receptacles.
I'm thinking about putting an outlet like this in for my garage. Does the addition of two USB outlets count a "Seperate receptacle" for the purposes of the above guidlines?
For the purpose of this question, I'm asking from Kansas.
