Cable ‘drop’ from overhead branch circuit to fixture

[Isaiah]

Construction used the vendor supplied pigtail (from lighting fixtures) to connect to conduit T fitting where it is spliced into the branch lighting circuit. The distance is approximately 5’ from the T to fixture.
The cable is Ty wrapped to the chain used for fixture support. Shouldn’t this be a flex conduit connection?

A lot of luminaires come with factory cords for that purpose. If the cord is supported, is typically supported in the manner you have described.

Don is there a NEC section that addresses this? Some drops are over 6’

See 410.62(C)(1). I don't see any restriction on the length.

don may correct me but, IMO, terminating in a "T" fitting does nor meet the requirements of 410.62. There is no :strain relief & canopy"
I feel it would need to be cord & plug,

Augie, there doesn’t appear to be any strain on the vendor cable since it is secured to the fixture support (chain).

The ones that I have done had a factory supplied strain relief. I would have no issue with using a cord grip with a conduit body. I would ignore the canopy requirement for an application like this. That part is intended for connection to a flush mount box that does not exist in this installation.

If challenged by an inspector how would you justify the install considering the "canopy" requirement in 410. ??

Just explain that the canopy has ZERO function where the luminaire is supplied from a surface mount conduit system. If the inspector insists, I would knock out the canopy, put the cord grip through the hole and screw the cord grip into the T fitting.

I will work on a PI for this as the current language does not anticipate this installation with exposed wiring systems.
