colors codes change why

No it doesn't but myself I hate cheap tape...Won't stick or becomes a gooey mess.

I was mostly making a joke. I use the better 3M colored tape in hopes to last as long as possible. I had some really cheap tape once that would fall off when you shut the enclosure's door. I use that only to wrap up my coils of romex :D

Slightly related to the original topic....

A few years ago, UK changed the colours for wiring three-phase.
The existing and the two new options are shown below.

Not the reversed functions of Blue and Black in the first of the new options. Imagine the potential for confusion when an existing system has to be extended. Half of it will be in the old colours and half in the new - and the interface will have both.

It's just one of a number of bl00dy stupid things we have done in this country to "harmonise" with the European Union.
It's a triumph of monumental stupidity over common sense.
 
Hows that?

I agree with Bob. That would be a stupid rule. It would be broken all the time anyway. I dont know about you but even if we had a standardized color code, I still wouldnt believe it. I have seen red as a ground, and green as a CCC. And like always, test before you touch.

Exactly.

Code wise Green has been reserved for EGCs for how many years now?

I still find green used as something else.

I think it is better for people to know how to figure out what they are dealing with without counting on the previous installer to follow the rules. :smile:
 
The emphasis of 110.15 is its color marking by the fact that is specifies it.

Otherwise it can be effectively marked with black tape or? Consistency is safer!

You may find this interesting.

1-80 Log #3658 NEC-P01​
Final Action: Reject
(110.15)

_____________________________________________________________​
Submitter:​
George Rohanna, Local Union #98 IBEW

Recommendation:​
New word (Purple).
Delete (Orange).

Substantiation:​
Orange is a ?B? phase color for all 480 volt systems, wye or
delta. The color purple should be used to identify a high leg on a 4-wire delta
system.

Panel Meeting Action: Reject
Panel Statement:​
The submitter has provided no technical substantiation
supporting a change of the high-leg color on a 4-wire delta connected system
from orange to purple. See Section 4.3.3(d) of the Regulations Governing
Committee Projects. CMP-1 notes to the submitter that orange has been the
standard color code for high-leg systems for many years, and that there is no
requirement in the NEC to identify the ?B? phase of all 480 volt delta or wye
systems as orange.

Number Eligible to Vote: 12​

Affirmative: 12
 
Another issue I had not thought of is this.

If the NEC required certain colors for phase identification that would rule out other means of marking.

What voltage and phase are these black condutors?

They are identified

2-289 Log #3226 NEC-P02​
Final Action: Reject
(215.12, FPN )

______________________________________________________________​
Submitter:​
Randall Opperman, Jr., O.S.C.Inc.

Recommendation:​
Add text to read as follows:
FPN: 1) 240 volt single phase systems shall be identified by red and black
marking
2) 240 volt 3 phase systems shall be identified by black, orange, and blue
mark
3) 480 volt 3 phase systems shall be identified by brown, orange, and yellow
markings
4) 208 volt 3 phase systems shall be identified by black, red and blue
markings.

Substantiation:​
215.12 does not specify how a branch circuit shall be
identified, yet it tells us to identify it. An industry standard for electricians who
use the NEC should be adopted by adding a FPN to the article.

Panel Meeting Action: Reject
Panel Statement:​
The submitter’s recommended fine print note contains
branch circuit identification requirements which are not appropriate in a fine
print note. Further the panel notes that the detail of how to identify a circuit
is intentionally not specified to allow flexibility for identifying circuits by
methods other than color.

Number Eligible to Vote: 12
Ballot Results:​
Affirmative: 12

Comment on Affirmative:​
BROWN, L.: In all, see Panel Action on related Proposals: 2-29; and 2-289.
 
I am sure green was reserved as a EGC at the time this service was installed.

Pretty sure green is a hot here but I did not bother to check. :smile:

What?

Black, Green, Brown is not the standard marking for 208Y/120? :D

Blue for the grounded conductor, tells me this was a non-US installer.
 
also interesting..neutral is bonded indicating service...but conduit is not; the pigtail fuse is priceless also..
same guys did your NM job ??:)
