I suspect that the answer is no, but want to double check.
Residential.
Can I have a circuit, protected by a double pole circuit breaker, that would have a neutral and both 220v, as well as 110v, outlets. Obviously, wiring would match the breaker's capacity.
thanks
No
Yes.
"Multiwire branch circuits shall supply only line-to-neutral loads. ... Exception: Where all ungrounded conductors of the multiwire branch circuit are opened simulaneously by the branch-circuit overcurrent device." [2005 NEC, Article 210.4(C)]
Bzzzt! Sorry, but thanks for playing.
Specifically permitted unter NEC 210.4(C), Exception 2.
This is great. I have existing conduit going into my basement "workshop". It supplies 110v right now. I want to rewire it to supply
20A 220v, with neutral, and will add 110v outlets on both legs, as well as 220v outlets.On the main panel, I will use a double pole 220v breaker so that ``all ungrounded conductors of the multiwire branch circuit are opened simulaneously by'' that breaker.
The reason for it I want to convert my drill press to three phase with VFD, mostly for tapping. I need 220v for it.
Also, on the same circuit, outside the basement wall, I want to add outdoor receptacles (110v and 220v) for my pool's pump. It would be GFCI protected and I will use outdoor rared hardware.
The above mentioned pump runs a water slide on my inflatable round pool, which also doubles as a water filter.
iAccording to Ignoramus2331 :
That sounds _way_ more than can be supported off a single circuit,
240/120 or otherwise. You'd be better off running multiple circuits, some dedicated 240, others 120. Or put a subpanel in the basement and do it from there.
Some pumps use a lot of power. The one you are talking about is probably not as high as some, but you should consider it.
The drill's power consumption could be high too.
Now *that* part is a potential problem.You'll want to split the multiwire circuit into two separate 120V circuits on the LINE (input) side of the GFCI, or use a double-pole GFCI breaker. Those aren't cheap.
Good reason for using GFCIs. But why the same circuit?
Right now, the pump is 1 honest HP and draws about 10A 110V. I do not think that it will be a big deal for a 20A circuit.

The pump is 1 HP, about 10 amps or even a little less (I should look at the nameplate). It is a lawn sprinkler pump by Wayne.
i
I would do the former (protect the outdoor outlets with an outlet GFCI, separate GFCI for 110v and 220v outlets).
All slots taken on the panel.

Half-height breakers are a good solution to that, if your panel supports them.
