Not sure. What if it were printed on with ink and it wore off. Would you have to go and write it back on?:laughing:

PROVE IT.

Prove that the paint did not damage or that it was listed for the purpose....
The references you provided have nothing to do with painting the outer sheath of a cable. 300.6(C)(2) deals with materials installed in adverse ambient environmental conditions, such as continued exposure to chemicals, solvents, etc. I don't believe this is intended to prevent one from painting the outer sheath for aesthetic purposes.

The Code is permissive in nature, that is unless something is specifically prohibited, many things not mentioned are permitted.

Painting is mentioned in the Code, in fact this is allowable when re-identifying conductors at termination points. It would seem illogical to allow painting of individual conductors while prohibiting painting of an outer sheath.

But since nothing I can say here will change your mind without absolute "proof" I will submit to the following challenge:

I have sent an inquiry to a major manufacturer of type NM-B cable asking specifically whether painting the outer sheath of their cable would violate any listings or Codes. If they respond that this is OK, they you will publically eat CROW.

If they tell me that this should not be done, I will concede.

Deal?

actually, the title of the section is:

Protection against corrosion and deterioration.

C is for non-metallic equipment (specifically lists cable with non-metallic outer jacket)

and 2 is shown below. Painting the cable would expose it to chemicals, more specifically, solvents so, to follow the remainder of the section, the cable must be listed for such use.

It does not give any time limitation such as "continuous" as you suggest.

I have never seen the sheathing on NM to be listed to be resistant to any chemicals in paint.

those "materials" if you will read the section, do refer to "materials". Look that up in the definitions.


and to your section about stating that painting is ok to remark a color. Sure, as long as the paint used is approved for use on that type of material. I can provide you with paint that will literally melt the insulation on the wire but by your argument, it would be ok to use that.

and now you are going to come back with the argument that; come on now. You have to use common sense. Well, do you know for a fact which paints will or will not harm the sheathing on NM? I know I don't so unless you can support your belief that it won't, then it is not ok to use it.

AS PROMISED, here is the text of my message to SouthWire concerning the painting of the outer sheath of type NM cable:


Message: I would like to know if there is anything that would prevent one from painting the outer sheath of type NM-B cable. Would this violate any of your listings or code requirements?
The response I received is:

The only thing that it would violate is the print legend on the cable, which is part of the listing.
Regards,

Southwire
So there you have it. You are correct in that covering the printing on the outer sheath violates the listing. However, if one were to install the cable face down (and not paint that part), and then paint the back of the sheath, you would have a nice finished appearance without violating the listing of the cable.

I still don't buy your arguments about using highly corrosive paints, solvents, etc, when one can use something as simple as LATEX paint on romex.

What is it with you and your obsession with not being able to paint anything?

Hey, score one for the anal guy.




my problem with painting things is as I read it, it is contrary to the code. I suggest your response from southwire was a bit of a blow off. You never mentioned what type of paint and I can assure you, I can find paint that would dissolve the outer sheath of NM. That, obviously, is not code compliant.

and to your "what's wrong with latex" position: you are the one limiting it to latex. The question was "is it ok to paint NM" You are limiting it to latex. Even in a house, not all paint is latex.
