Well, I guess "shall be effectively bonded together" has different meanings to people..

If the conductor is bonded to the enclosure and the raceway is bonded to the enclosure they are in fact effectively bonded together both in the physical sense and the electrical sense.

True statement.

But the book says " by bonding each end of the raceway to the GEC "

Yes and I have done that by bonding the both the raceway and conductor to the enclosure.

Now if that said "by bonding each end of the raceway directly to the GEC"

I would buy what your selling. :smile:

That always been my opinion too. The words directly would make it mandatory to physically connect the two where the conductor exited the raceway. I think that I said that back in post #6. :rolleyes:
 
Saw this ,..thought I would share it ,..seems to me that the bonding at both ends is required when not physically continuous. This guy had three proposals to try to make this section more usable ,..I'll post them if you folks want to see them

(250-64(E))
Final Action: Accept in Principle
Submitter: Michael J. Johnston, Int?l Assn. of Electrical Inspectors
Recommendation:
Revise Section 250.64(E) as follows:
(E) Enclosures for Grounding Electrode Conductors. Metal enclosures for grounding electrode conductors shall be electrically
continuous from the point of attachment to cabinets or equipment to the grounding electrode and shall be securely fastened to the
ground clamp or fitting. Metal enclosures that are not physically continuous from cabinet or equipment to the grounding
electrode shall be made electrically continuous by bonding each end to the grounding electrode conductor. Bonding shall apply at
each end and to all intervening raceways, boxes, and enclosures between the service equipment and the grounding electrode. The
bonding jumper for a grounding electrode conductor raceway or cable armor as covered in 250.64(E) shall be the same size or
larger than the required enclosed grounding electrode conductor. Where a raceway is used as protection for a grounding electrode
conductor, the installation shall comply with the requirements of the appropriate raceway article.
Substantiation:
The revised text added to this section is not new information to the Code. These two new sentences were relocated from Section
250.92(A)(3) and Section 250.102(C). Both of these requirements exist in the current edition (2002 NEC) and relate directly to the metal
enclosures for grounding electrode conductors. This revision would enhance usability by locating the requirements together rather than
apart in different locations. See separate companion proposals to Section 250.92(A)(3) and 250.102(C).
Panel Meeting Action: Accept in Principle
Revise Section 250.64(E) as follows:
(E) Enclosures for Grounding Electrode Conductors. Ferrous metal enclosures for grounding electrode conductors shall be electrically
continuous from the point of attachment to cabinets or equipment to the grounding electrode and shall be securely fastened to the
ground clamp or fitting.

Ferrous metal enclosures that are not physically continuous from cabinet or equipment to the grounding
electrode shall be made electrically continuous by bonding each end of the raceway or enclosure to the grounding electrode conductor.

Bonding shall apply at each end and to all intervening raceways, boxes, and enclosures between the service equipment and the
grounding electrode. The bonding jumper for a grounding electrode conductor raceway or cable armor as covered in 250.64(E) shall be
the same size or larger than the required enclosed grounding electrode conductor. Where a raceway is used as protection for a grounding
electrode conductor, the installation shall comply with the requirements of the appropriate raceway article.
Panel Statement:
The panel accepts the relocated text from Sections 250.92(A)(3) and 250.102(C) (Proposals 5-184 (Log #1570) and 5-190 (Log #1536))
to be incorporated in this section and adds the words "of the raceway or enclosure" between the word "end" and the word "to" in the
second sentence and added the word ferrous in two places. The panel concludes that the relocated text provides clarity and usability to
this section. The word "ferrous" was added to make the requirement technically correct.
