Is iit OK to land a white wire on a breaker for a 220v circuit ? I was told no and taping small gage wire is a no no.

Depends. Romex, MC cable etc. you could use can be fed with a two wire cable on a breaker Example: 240 volt AC unit that doesn't need a neutral. Then re identify the white with tape or a marker.

Individual small wires THHN etc. your not supposed to re identify. But I have done it a few times

In general this is true but there is an exception when using cable. The others already mentioned it.

Btw, in Canada they make a nm cable that has Black, Red and an equipment grounding conductor specifically for 240v circuits and switch legs.

The wire coloring rules are made to accommodate how cables are made.

I like to call that DC Romex. :giggle:

I have done it also but is it against code in NYC is my main question, I was under impression that you can't land a white wire on a breaker and can't remark a small wire like a 14 , 12 , 10.
 
The actual section is 200.7(C)

(C) Circuits of 50 Volts or More. The use of insulation that is
white or gray or that has three continuous white or gray stripes
for other than a grounded conductor for circuits of 50 volts or
more shall be permitted only as in (1) and (2).
(1) If part of a cable assembly that has the insulation permanently
reidentified to indicate its use as an ungrounded
conductor by marking tape, painting, or other effective
means at its termination and at each location where the
conductor is visible and accessible. Identification shall
encircle the insulation and shall be a color other than
white, gray, or green. If used for single-pole, 3-way or
4-way switch loops, the reidentified conductor with white
or gray insulation or three continuous white or gray
stripes shall be used only for the supply to the switch, but
not as a return conductor from the switch to the outlet.
(2) A flexible cord having one conductor identified by a
white or gray outer finish or three continuous white or
gray stripes, or by any other means permitted by 400.22,
that is used for connecting an appliance or equipment
permitted by 400.10. This shall apply to flexible cords
connected to outlets whether or not the outlet is supplied
by a circuit that has a grounded conductor.

That's a by-product of the general rule of not being allowed to use white conductors as hots.

As above, there are allowances for cables, but there's "no excuse" for using pulled white conductors as hots.

I do not know what changes New York has made to the NEC, nor their own additions and exceptions.
