According to zxcvbob :


If you wrap green electrical tape around both ends just up from where the
insulation is stripped, it is no longer a red wire. All the red in the
middle doesn't count.


Both the NEC and CEC prohibit this.

You can make a white wire "hot" by marking it (with tape or nail polish),
but you can't make a black or red wire into a ground or neutral.

Strange, but true.

??? Large gauge wires are only available in black and are routinely (in
Minnesota, anyway) taped white for grounded service entrance conductors.
The local inspector requires that the grounded conductor be marked.
I realize that service wires might be different than circuit wires, but
where are you gonna get white #6 wire? Or even #8?

Not arguing, just confused. (for old work I'd tape it green even if it
was a technical violation)
