Machines came in from Germany with factory harness already made up (pic #2). The wires were landed in a 600 amp non-fusable disconnect fed from mcc. The wiring (pic#1) was terminated as pictured. My question is should the gray wire be identified by blue or red tape as a power carrying wire according to NEC205 re-identification ? This cable was listed in Germany as part of the factory machinery but when used in the USA must it follow the NEC guidlines and standards ?
 
If this is factory installed wiring within a listed piece of equipment, IMO the NEC doesn't apply to that wiring.

if it is part of the machinery, than NEC does not really apply. i don't think it matters whether ithe machine is listed or not. machines are not normally listed in any case. just what entity listed it?

Maybe it was a bad choice using the term "listed". I agree that the factory wiring internal to a "machine" would not be regulated by the NEC.

Unless the portion of the NEC you are referencing requires listing or a local code requires listing of the item you are installing, a listed product is not required.

In the NEC, not all items are required to be listed.

NYS codes require all material installed to be listed. I know, a very unrealistic requirement, but there none-the-less.


90.4 in the NEC permits the AHJ to forego the listing requirement if he/she feels by their professional judgement the material is suitable for the installation.
 
Funny to see this now!

Hooking up refrigerated cases on a new department store build the inspector noticed that the leads to the temp sensors were green. We joked around about it and he asked me how good of a sense of humor the next guy up the food chain from me had. Todd is the guy's name and he had had a couple of long bad days trying to get all the dozens of computer controlled cases working properly so I figured he was fair game for some entertainment.

The inspector and I found Todd and the inspector brought up the green wire thing and asked Todd how many there were out on the floor. Todd said 'hundreds' which was probably accurate. The inspector to Todd he had to either change the color of the green wires or ground them all (how he did all this with a straight face is beyond me....practice maybe?:grin:). Todd, respectful of authority agreed to comply. Undaunted to get Todd's goat, the inspector asked "can you have it done by tomorrow?" Now Todd is starting to squirm and the inspector asked if the sensors were factory installed and did they have a UL sticker. Todd answered yes to both. The inspector said 'OK, never mind' and started walking toward the door. He then told Todd he was jerking his chain and we were cleared to cover our work.

Who say's inspectors aren't human? :grin:
 


Wireman .,

That wire colour combation that is standarized European colour code and we adopted new colour code couple years back to standarized the connetions format.

so here a quick rundown Black , Brown , Grey = phase conductors Green with Yellow stripes that is grounding conductors if any chance you see bleu that is for netural conductor

And just beaware most of the Europeans cable are metric sized so just watch out when you do make the termations.

Merci,Marc
