Am I correct in my assumption that for colored identification 210.5 now specifies:
Grounded DC -- White or Gray
ungrounded Positive -- Red
ungrounded Negative -- Black?
Further this text (210.5(C)) is copied to 215.12(C)(2). Does it make sense to use a reference back to 210.5 instead?
This is done in 210.5(A), 215.12(A), 310.110(A), 382.104(B), ... referring to200.6 for grounded conductors.
The nec_draft.pdf states:
210.5 Identification for Branch Circuits.
(A) Grounded Conductor. The grounded conductor of a branch circuit shall be identified in accordance with 200.6....
....
(C) Identification of Ungrounded Conductors.
....
(2) Branch Circuits Supplied From Direct Current Systems. Where a branch circuit is supplied from a dc system operating at more than 60 volts, each ungrounded conductor of 4 AWG or larger shall be identified by polarity at all termination, connection, and splice points by marking tape, tagging, or other approved means; each ungrounded conductor of 6 AWG or smaller shall be identified by polarity at all termination, connection, and splice points in compliance with 210.5(C)(2)(a) and (b). The identification methods utilized for conductors originating within each branch-circuit panelboard or similar branch-circuit distribution equipment shall be documented in a manner that is readily available or shall be permanently posted at each branch-circuit panelboard or similar branch-circuit distribution equipment. [ROP 2?23]
(a) Positive Polarity, Sizes 6 AWG or smaller. Where the positive polarity of a dc system does not serve as the connection point for the grounded conductor, each positive ungrounded conductor shall be identified by one of the following means: [ROP 2?23]
(1) A continuous red outer finish. [ROP 2?23]
(2) A continuous red stripe durably marked along the conductor?s entire length on insulation of a color other than green, white, gray, or black. [ROP 2?23]
(3) Imprinted plus signs ?+? or the word ?POSITIVE? or ?POS? durably marked on insulation of a color other than green, white, gray, or black, and repeated at intervals not exceeding 610 mm (24 in.) in accordance with 310.120(B). [ROP 2?23]
(b) Negative Polarity, Sizes 6 AWG or smaller. Where the negative polarity of a dc system does not serve as the connection point for the grounded conductor, each negative ungrounded conductor shall be identified by one of the
following means: [ROP 2?23]
(1) A continuous black outer finish. [ROP 2?23]
(2) A continuous black stripe durably marked along the conductor?s entire length on insulation of a color other than green, white, gray, or red. [ROP 2?23]
(3) Imprinted minus signs ??? or the word ?NEGATIVE? or ?NEG? durably marked on insulation of a color other than green, white, gray, or red, and repeated at intervals not exceeding 610 mm (24 in.) in accordance with 310.120(B). [ROP 2?23]
