I'll hazard a guess that it could be if the connectors were used as a required disconnect for whatever machinery is running on them, as the plugs would not be quickly and easily withdrawable.

As above, if the caps are the disco, yes, a red sticker.

Also, is this a use of cord that is not compliant with Art 400.7 / 400.8 limitations to usage of cord? As the install is not completly visable, no determination can be made.

If pull out is a problem, the installer should have considered twistlock devices, in lieu of ty-wraps.

Also, the sealtite flex doesn't appear to be secured within 12" of the boxes, so yes.
350.30(A)
We're also looking at 225° (at least) of bend just to get out of the center box. Could it possibly exceed 360° between pull points?

Generally we use twist locks. [Linked Image]

This looks to me like a under a data room floor.

If it is under 645 rules the liquid-tight need not be secured, the same for the box. 645.6(E)

We do a lot of installs where the UPS maker supplies pre-made liquid-tight whips with FS type boxes and receptacles.

For better or worse all you do is drop them in like extension cords.

The 3/4" square tube legs that are bonded with the bare copper along with what looks like a piece of fiberoptic cable in the bottom of the picture are what makes me think this is a 645 room.

Sorry to be away for so much activity.
It is an Article 645 installation. The plugs are for computer servers, not requiring a means of disconnect like a motor.

The server cords do not have twist lock plugs, hence the straight blade receptacle. No one wants to cut the factory plug off a server.

Bob,
Don't you mean 645.5(E)??

Now read 645.5(D)(2)
"installed in accordance with 310.11"
These don't look like a specially listed whip to me.
