For driers code is 10/3 with a 4 wire plug because many driers run
only the element on 220, with the motor and controls on 120 - which
now requires a neutral. Used to be you could use the ground as a
neutral and get away with it. Not any more.

Just curious. Why "not anymore"? Has the nature of electricity
changed, or just the code? If just the code, what justifies the
increased complications?

They were just trying to make the code more consistent. The only
exceptions to the rule were dryers and ranges and since you were going
to be using 10/3 Romex anyway, why not use the ground wire that was in
there?
As I said before there were other restrictions on this.
I've seen a lot of 10/2 with ground used for driers in the past, and
8/2 for ranges YEARS ago.
