Our house has 3-conductor wiring for the range and dryer. Would it be OK

Yes it would be OK,

No, it's not. All conductors for a circuit are required to be in the same
raceway or cable. [2005 NEC, Article 300.5(I)]

305-I is underground (buried). You want 300.3-B.

Of course, "305-I" is not what I wrote. Look again.


Sorry - my fingers didn't type what I told them to. Should have said
300.5-I - which is underground (buried). 300.3-B is appropriate.
