600v cable support
600v cable support
(OP)
A contractor has installed the integral motor/pump leads with practically no bending radius and no supports. Approxiamately 14 feet of 250kCM 600V cable is DANGLING from a mezzanine support (were the disconnect is located). (About 7 feet veritcal and 7 feet horizontal just hanging around.) THe suports at the mezzanine are the wire pulling eyes. The contractor is fighting all added expenses on this project including fixing this installation. He has noted that NEC requires bending radius for 600V an above. He has had a third-party cable test that checked out fine. What can I use as leverage to pressure him into resolution-besides cable must be protected from physical damage-NEC 300.4. Any advice?

Also, the only articles in chapter 3 that don't require tray or raceway for cables that are not direct bury are 394, 396, and 398.
394 is Concealed Knob-and-Tube and does not apply.
396 is Messenger Supported Wiring. You make no mention of a messenger wire, so it sounds like this doesn't apply.
398 is Open Wiring on Insulators. Might apply, but doesn't sound like the installation meets 389.30.
I often threatened contractors who didn't want to fix poor workman ship that I would install a sign at the installation that stated that the work was "Installed With Pride By ______". Nobody ever seemed to want a free sign advertising their workmanship.

PS I like that sign idea!
RE: 600v cable support
The cord has to be listed for the application. The NEC and the manufacturer will both list minimum bending radius for the cord.
IF the installation was acceptable for some reason it will need cord grips and strain reliefs.
Does it pass a common sense test? Is the cord in the way? Is it where people will hang their coats on it? Will it "cloths line" people walking by?
If it fails common sense and should start a fire and/or injure someone remind the contractor that you have a picture of the installation. The lawyer that goes after him will probably go after you as well so it's time to get tough.

I am getting increasingly tough these days.
