Default can I put the white tape on a #12 black wire to use it as neutral wire?

not a small size like #12 copper

Is it in a pipe or in a cable?

We do it with multi-conductor teck cable all the time (see rule below). I've been on a few places that wanted it covered with white heat shrink all the back to the connector, which violates the rule.

From the 2018 Handbook:
4-030
Subrule 4) allows the insulated neutral conductors in multi-conductor cables to be permanently identified by painting or other means where the internal conductors are accessible and visible. Other acceptable means are coloured insulating tape or coloured heat-shrink tubing. In many cases, these means of identification are easier to apply in the field and can be more permanent than painting.
Subrule 4) requires that, where such means are used to identify insulated neutral conductors, the manufacturer’s numbering of the conductor remain legible.

READ 200.6. pretty much says any colored wire can be used as a grounded conductor so long as it is properly identified as a white wire. Meaning paint it white. No rules about what wiring method is employed. ***

200.7 gives us the rules about re-identifiying a white conductor to another color such as black or blue for use as an ungrounded conductor. That is where it is limited to cable assemblies.




***- Inspectors cannot fathom this wording from 200.6 and will pull the "I interpret this to mean....." crapola on you every single time they find you trying to re-identify a white wire to another color . But that doesn't change the fact that the code allows it. This is your mactip of the day!

The code allows a white wire in a cable assembly to be used as a hot conductor if re-identified, but I don't think it,goes the other way, that is, another color being used as a neutral.

Oh crap, I got this whole thing backwards what the op was asking. I did address Coolwill's statement though. Read the code I posted in your code book.


Coolwill, you just learned something from your ole buddy Mikey............ So now we are 1 / 1000.

Where is this Section 200 you speak of? My Code Book only goes up to 86.. Guess the 100 of us figured we can't be bothered with the rest.. LMAO!

PS.. The OP is a Canuck!

That’s one reason I don’t like the enhanced mobile version on the phone. It doesn’t show the information of the member, just the name. It’s the default when I come here on the phone. A couple of days ago it wouldn’t let me leave the enhanced mobile version unless I signed in. Now when I first come here I can click on one post, then it switches to some BS ad that tells me I won a chance to spin the wheel and infect my phone. I have to close the tab, come back, sign in and leave enhanced mobile version ASAP.

Do ya think ET has chased off enough users with their advertising greed? I think so.

I don’t have a problem with any other site I go to on the phone, only here.
