The NEC specifically requires that neutral conductors 6-gauge and smaller
be
white or gray end-to-end. It's absolutely a Code violation to re-label a
red
wire as a neutral, unless it's larger than 6-gauge.
[NEC 2005, Article 200.6(A)]

Why does it only apply if the conductor is 6-gauge and smaller. Do you mean
smaller gauge (larger wire), or smaller wire (larger gauge)?? This gauge
unit seems to be defined backwards (and is #1 gauge the largest wire
possible?)



The reason for requiring continuous marking up to six gage is that
larger conductors are not readily available with continuous jacket color
coding.

Wires larger than #6 American Wire Gage are only required to be marked
at the terminations and other accessible points.

When the gage was devised it was believed that #1 was the largest gage
possible. Then gage 0; said as ought; was added, followed by 2/0, 3/0
and 4/0 (four ought) until they finally gave in to the inevitable and
began using circular mills to size wires larger than 4/0.
