Sorry...neglected to answer your original question. I believe the NEC
frowns on connecting across one phase of a 230V circuit to get 115V. That
WOULD double the current on the neutral and result in a potential overload.

Utter nonsense. It would do nothing of the sort.

In a circuit wired as he described, with (for example) a 10A load at 240V and
a 15A load at 120V, the current in the neutral conductor is 15A. (The 240V
load places *no* current on the neutral.)

Now add a 17A load at 120V on the opposite leg.

One hot leg is drawing 10 + 15 = 25A. The other is drawing 10 + 17 = 27A. And
the current in the neutral is 17 *minus* 15 = 2A.
