What Jim says here is correct.
The old exception that allowed returning 120V loads to the bare or green
grounding wire of a 240V circuit was very limited

I was always under the impression that the ground wire must be sized for
the circuit overcurrent rating (i.e. breaker/fuse rating). I have on

I'm not an electrician, but I am currently having my house wiring
re-done by an electrician and this is my understanding:
If you want to run 220V and 110V outlets from the same breaker, you need
to use a sub-panel with separate breakers for the 110V circuits. Four

few large appliances (dryers, stoves/ovens, and water heaters IIRC)

In retrospect, its better if you contract a licensed electrician to
run 240v wiring as his license is at risk and is liable if codes are
violated. If you are not sure of the code and regulations, then I
would say don't DIY.
I am lucky as there is no zoning or covenants where I live.
Installing a 240V outlet is not a big deal unless the construction of
your home makes it difficult to run the cable. Barring that, a competent
electrician should be able to do that in a half day; a difficult run
could double the work. All that is required is a pair plus a Green wire.

A lot of the older amps (Thunderbolt for example) had 120 V fans wired

I think that used to be legal, but it is no longer, and it's very bad

Electric ranges used to have a 110 VAC outlet in which the ground and
neutral were wired together. (The 220V plug had only three prongs.) I
always wondered how they got away with that.
