2-280 Log #2224 NEC-P02 Final Action: Reject
(215.4)
______________________________________________________________
Submitter: Donald A. Ganiere, Ottawa, IL
Recommendation: Revise as follows:
215.4 Feeders with Common Neutral.
(A) Feeders with common Neutral Two or three sets of 3-wire feeders or two
sets of 4-wire or 5-wire feeders shall be permitted to utilize a common neutral.
(B) In Metal Raceway or Enclosure. Where installed in a metal raceway or
other metal enclosure, all conductors of all feeders using a common neutral
shall be enclosed within the same raceway or other enclosure as required in
300.20.
Substantiation: There is no code violation in using a common neutral so the
specific provision to use one is not required.
Panel Meeting Action: Reject
Panel Statement: The panel disagrees with the submitter’s substantiation.
Section 215.4 (A) is the requirement which limits the number of feeders that
may share a common neutral.
Number Eligible to Vote: 12
Ballot Results: Affirmative: 12
