 Quote:
330.30(D) Unsupported Cables.

Type MC cable shall be permitted to be unsupported where the cable:

(2) Is not more than 1.8 m (6 ft) in length from the last point of cable support to the point of connection to a luminaries (lighting fixture) or other piece of electrical equipment and the cable and point of connection are within an accessible ceiling.

For the purpose of this section, Type MC cable fittings shall be permitted as a means of cable support.


Some interpret the last sentence as allowing the support up to 6 feet from each fitting to permit 11 feet, 6 inches of cable from a box to a luminaries without support.


Opinions?

They are stretching a clarification at the end to defeat what the previous paragraph clearly states.

All it is saying that if you are going to a fixture or piece of equipment, the last 6' doesn't need to follow the normal support rules.

Art 320 has the same wording, but Art 334 has left out the last sentence from similar wording. Does this mean the NM fitting is does not follow the same requirements?
