I have a 30Amp 240V (4 wires) circuit. And I want to branch a single 120V 20A outlet on this circuit for convenience. I was hoping to find a Decora compatible breaker that I can used to protect the 20A outlet. Such that I would have a 3 slots box with:
- A 30 Amp 240V Outlet connected to the 10GA wires
- A 20 Amp breaker connected to one hot leg of the 30A circuit with 10GA.
- A 20 Amp 120V outlet connected to the breaker.
My understanding is that this setup would be code compliant but that type of "switch box breaker" doesn't seem to be a thing. Any ideas? I'm I thinking of this wrong?
Context: This circuit is intended to power an electric grill but having a 120V in that location would be convenient as well to power yard tools and such when the grill is not in use or power some low power things like string lights the grill is in use (or not for decorative lights in the winter).
