    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.

    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?
