FLEXIBLE CORDS

[timbucktwo]

Could anyone clear up the interpitation of the uses of flexible cords. According to 400.7 I can use flexible cord for wiring of luminaires (fixtures) and 400.8 tells me that UNLESS SPECIFICALLY PERMITTED IN 400.7 FLEXIBLE CORDS AND CABLES SHALL NOT BE USED FOR THE FOLLOWING: As a substitute for the fixed wiring of a structure and that I cannot attach to a building surface.
How far can I run the 14-3 SOE to a fixture from a branch circuit before it is considered wiring of a structure. And are there any exceptions to attaching to a building surface other than 368.8 for busways.
I wonder how SPECIFICALLY PERMITTED is used in this interpitation.
What would be the normal installations of installing a luminaire 30-40 feet along the ceiling of a building to a outside green house open to all types of weather conditions.

timbucktwo,

It does not Specifically permit,gas stations or air conditioners fixed in place,but it does allow wiring of fixtures.
You have to use an approved wiring method to a j-box close enough to the fixture that support for the cord will not rely on the building structure. That leaves you right above the fixture. IMO this is the intent.

That is the way I interpretated the code also but I am getting some argument from a contractor. Just wanted to get someone elses opinion. Thanks
