Need to find in NEC

[armyofdone]

is it legal to have a ceiling drop of sjo end up in an UNMOUNTED metal 4x4 box. Basically just dangles there

 

[iwire]

No, 4"x4" square boxes are not allowed to be 'pendent' supported.

You need a box with a threaded hub.

Is that code rule in 314?

314.23

314.23

maybe I did not read the OP correctly but the way I am reading it he has SJO cord in a approved manner and has a 4x4 Jbox at the other end ..So 314.23(H)1 box supported by cord would be allowed...

Not exactly.

(1) Flexible Cord. A box shall be supported from a multiconductor cord or cable in an approved manner that protects the conductors against strain, such as a strain-relief connector threaded into a box with a hub.

A 4x4 box does not have a hub. The hub must be a part of the box.

He also said an UNMOUNTED 4x4 box. The unmounted part is a violation on it's own.

"such as", "such as", Hmmmm, could there possibly be other approved means to protect the conductors against strain?

Sure, a 'pendent box' would be another.

I don't got no PHD in English, or nothin', but, in my opinion, the words "such" and "as" in 314.23(H)(1) merely show the one example, but do not prohibit other methods of protecting the conductors against strain.

Any other method other than the hub would be subject to approval.

314.23(H) Pendant Boxes. An enclosure supported by a pendant
shall comply with 314.23(H)(1) or (H)(2).

(1) Flexible Cord. A box shall be supported from a multiconductor
cord or cable in an approved manner that protects
the conductors against strain, such as a strain-relief
connector threaded into a box with a hub.

Approved. Acceptable to the authority having jurisdiction.

If that is a hair you want to split with OSHA be my guest, I know for a fact OSHA fines for pendent boxes made from 4" squares.

As was pointed out above a 4" square is also not listed for 'KO' support.

Not exactly.

A 4x4 box does not have a hub. The hub must be a part of the box.

Or he can use a WP box with threaded ko's. And, of course seal off all unused ko's. And add strain relief.

Not so fast, the listing and labeling for most if not all standard WP boxes requires they be mounted by the tabs provided.

I think you would have to move into a malleable steel type FS or FD box that is designed to be supported by the hubs.
