I have a 240 volt breaker in my main breaker panel feeding a local outdoor disconnect (black, white, red & ground) for an outdoor sauna. Can I take leads off the black, white & groun, before the disconnect and make a local 120 panel with its own breaker?

1How many amps is this 240V breaker, how many amps does the sauna pull, and how big is the wire running to the sauna disconnect?– ThreePhaseEelCommented Jun 25, 2019 at 0:40

I think what you actually want to do is install a subpanel. The subpanel can then include both 120V (e.g., 15A or 20A) breakers for receptacles or lighting and a 240V breaker for the original sauna use. The specifics will depend a bit on:
- Existing wire size
- Existing breaker size
- Requirements of the existing sauna circuit
Keep in mind that there are GFCI requirements (which can be handled in the subpanel or possibly in the main panel) and that ground & neutral should be kept separate in the subpanel. The subpanel could have a main breaker that is larger than the breaker in the main panel that is connected to the wire that goes to the subpanel.

1If it's on the same building, it doesn't even need a main breaker of its own... Commented Jun 25, 2019 at 0:39
