Bob,

That brings up a question.
You buy a house with the 3 prong outlets, and your stove and dryer are the newer 4 prong style. Is it allowed ( by code and/or manufacture) to install a 3 prong cord on the stove, dryer?
Which means those circuits already 'have' the four prong receptacle, and, presumably, four wires.

In answer to Rick's questions, if the receptacles are already four prong, then a four conductor cord and plug would be needed to install the range or dryer.
I'm guessing that is what the manufacturer's installation instructions will say, and the code does not say that you may change the receptacle out to a three prong type from a four prong type. (But I could be wrong, I've been wrong before.)
