    What does that mean ??

      Meaning the code would not limit receptacles to 20amp circuits because someone might violate 240.4 (D)

        Then my original answer stands.

              But are you going to see 4,400 to 4,600 watts of load on it? Doubt it.


              Ultimately 20amp OCPDs would be used, but the real world is different.

                To help us understand your thoughts a little better, why would the same not be able to be said about any device on any circuit?

                Why not ask: "Why shouldn't we be able to wire 15/20a receptacles on a 60a circuit?" What's different in your example?

                  But, couldn't we apply that train of thought to most any Device/OCPD combination if we wanted too?

                  Why try and reinvent the wheel?

                    A short circuit might melt the plug to appliance flex cord before the breaker trips, if at all.

                      Unfortunately reinventing the wheel is the norm

                        Same with a lamp cord on a 30a circuit.

                          But not for a 20?

                              I'd rather see a #18 on a 20a breaker than on a 30a.

                                Is this a question about the #10 neutral some partition wiring includes?

                                Or do you want to reduce the quantity of circuits to feed cubicle wiring?
