That=E2=80=99s simply not correct, unless there has been a major code =
change since I left the industry.

Take a look at Home Depot=E2=80=99s romex wire section next time you go. =
They have (using 12 AWG as an example) 12-2, 12-3, 12-4, etc, and the =
most common usage is is to connect multiple branch circuits with a =
common neutral between them. All the neutrals are being tied back to the =
neutral bar in the breaker, so technically EVERYTHING is connected to a =
neutral ties together somewhere in the electrical panel.

You may be correct that you won=E2=80=99t see this done with smaller =
wire, like 14 AWG, 16 AWG, etc., as the potential load on the neutral =
could be greater than the NEC specifies for such small wire. If you=E2=80=99=
re using 12 AWG (rated up to 30 A as of the 2005 NEC) or thicker, you =
won=E2=80=99t run into that issue.
