3-56 Log #2233 NEC-P03
Final Action: Reject
(300.5(I))
____________________________________________________________
Submitter:
Donald A. Ganiere, Ottawa, IL
Recommendation:
Revise as follows:
(I) Conductors of the Same Circuit. All conductors of the same circuit and,
where used, the grounded conductor and all equipment grounding conductors
shall be installed in the same raceway or cable or where individual conductors
are used, they shall be installed in close proximity in the same trench.
Substantiation:
It appears that the current wording would permit the use of a
three conductor cable containing the three phase conductors and individual
conductors for the grounded and grounding conductors installed in close
proximity in the same trench. This proposal would require that all circuit
conductors be in the same raceway, or if individual conductors are used that
these individual conductors be installed in close proximity in the trench.
Panel Meeting Action: Reject
Panel Statement:
The requirement is already provided in the existing text in
300.5(I) for underground raceways or cables. This section works in conjunction
with the requirements in 300.3(B)(2), where permission is given for a cable
assembly installed in accordance with Section 250.134(B), Exception No. 2, for
dc circuits. Making this proposed change would make this dc application a
code violation in this section and a conflict with the permission in 250.134(B),
Exception No. 2.
