does any one know of any code nec or nfpa that says you can not use a 15a receptacle in an industrial setting.
this is in a thermoplastics plant and the original installer used el cheapo 15a on about half the floor. im in the process of changing them but i was asked if it was actually code or just poor design.

If it happens to be a single receptacle served by a 20 amp circuit, it needs to be a 20 amp receptacle. Resi, non-resi, or otherwise.
 
The problem is not the 15a receptacles...it is the grade of receptacles that were used. If you take the face off a 15 and 20 amp receptacle of the same brand and grade you will not be able to tell them apart as the "guts" are identical. Also if you don't have any 20 amp cord caps there is no reason to install 20 amp receptacles.

Can't say as I agree.

20A receptacles I see have much higher contact grip than for the 15A ones. The diffrence is dramatic.

But between the same grade of receptacles, or are you using a higher quality 20A? I can't tell a difference between a Hubbell 5262 (15A) and 5362 (20A).
 
Can't answer regarding those model numbers. The force to plug in and remove for the last ones I bought was much different. Did you notice any difference?

RC,
The exact same brand and model? Everyone I have taken apart has idential guts when you are looking at the same brand and model. The only difference has been the face.
