BUT I almost got 'dinged once for using a piece of 12/2 yellow ( black and white conductors) for a 240V electric heater instead of the 12/2 red ( black and red conductor), even though I identified the white wire as a hot.

The inspector probably mentioned this because you cannot tape any wires under a certain size.(if thats how you indentified it) Just like you can't use 3 wire BX for a isolated ground anymore. You have to use the AC90 with a bare bond wire and insulated green wire.
