I've been to Lowe's and Home Depot and seen
the plethora of 220 plugs they carry. It seems that clothes dryers and
electric stoves now used a four conductor plug (rather than the old
three conductor) supposedly called for in the latest National Electrical
Code revisions.
Yes, the NEC has changed this. The ruling now is that "ground, bond" can
ONLY carry fault current and not operating current, therefore a separate
nuetral wire (white) is needed if any device requires 120v. It is wise to
have a
nuetral (white) wire available in a 220 volt system should it be required.
