Got a situation where an office desk needs to be able to move up a down on a wall. The branch ciruit feeding the desk ends as a receptacle on the wall. The 2amp monitor is the only load on the desk.

Igus chain filling VERY quickly. Can I run a 16/2 SO chord plugged into the branch ciruit receptacle, through the Igus chain and end in a duplex box that the monitor plugs into? 12/2 literally will not fit any more.
 
In some cases you can have cord drops.But what your trying to do is have a receptacle on #16 sj cord.That simply is not safe or legal.Offer them a receptacle on the wall and let them buy an extention cord.

Well I could put an extension cord in the Igus but what is the difference?

What code does it violate? What is the difference between an extension cord plugged into the receptacle and the monitor into the extension cord or a SO cord plugged into the recaptacle with a box and single recpetacle on the end of the SO?
 
According to your profile, you design command and control vehicles. It seems to me that this falls outside the scope of the NEC, which does not apply to "automotive vehicles other than mobile homes and recreational vehicles." (90.2(B)(1)). Who is the AHJ for these vehicles, and which portions of the NEC do they consider applicable?

What is "Igus chain"??

What type of box (duplex box) would you want to use?

I am the Engineer and AHJ. We are committed to following the NEC based on our own standards and specifications in government contracts. So when there is a judgment call I just make it. Of course since there is no inspector looking over my shoulder I want to be careful to walk a straight line.

Do you have any thoughts on my OP?

The only thought I have is right now you have 2amps load, that may change

at any time to say, 1500w load, and running on a #16 awg.

Use of the extension cord does not really fall under the NEC.

Wiring of the cord in the manner you speak of is a violation of 440.8(1) at the least.

Even though it seems very unlikely that the receptacle right behind the monitor would ever be use for anything else I agree I cannot do what I wanted. What I've decided to do is use some SJTW cord 12/3 for the purpose. It has a considerably smaller diameter than the standard SO I use.
