On the bag 3M stackits it list only the use of 14/2 ,12/2 and 10/2...My question would be If I put a 12/3 in the stackit am I going against man.. instructions and are there other stackits out there that are rated for 3 wire Romex?

The info on 3M's website says that it's also good for round cables up to .30" in diameter.

Here's the paper that comes in the bottom of the box when you buy a whole case of stackers:

I admit I have used a stack it or two....I dont know if there is more info ...but the way I read the info from Marc it looks like you would only be able to put 2 12/3's in one stackit.....
 
Sorry MD, After I went to your link I noticed that. From my link it looked like 2 different sizes. So much for taking short cuts on searches LOL
 
In the testing drawing, they showed eight 14-2's reaching a stabilized temperature of 57.something C. Does that number's being below 60 C mean that eight 14-2's can be used with 15a OCP?

If there are not two or three loaded Stackers in a line, which might effectively constitute bundling, does any derating need to be considered? Here's an example of what I mean:

Added: I don't mean three in a line like I show them above, but keeping several cables in parallel for a distance.

If 4 nm cables of 14/2 are stacked or bundled (I am not sure it would be bundling) then derating would not be an issue 25amp * 70% = 17.5 amps-- still good for 15amps

How about eight 14-2's? At what point does bundling begin?

If the point of being concerned about bundling is to limit heating, the document shows that this is not really a concern with full Stackers. Because of that information, I wouldn't really worry about it myself when using that product.

Believe me, I don't.
