A friend of mine asked me a question I didn't know the answer to, so I
told her I'd ask you guys.

She has a stove-oven/microwave combination. She is going to get a new
stove/oven and a microwave but the microwave will be separate. Currently
(heh) she has just the 220V outlet for the stove. Can she take one leg of
the 224V circuit and run an outlet for the microwave? Her reasoning is
that she should be able to since it was done before, just inside the
stove.

What say those more knowledgeable?

Not a good idea.

Run a separate 20 amp 12 gauge line from a breaker serving only the
microwave.
