Junction Boxes

[CtChuck]

Its been a while since I went through schooling on the NEC. Seeing that I never did get into the Electrical trade, I work as an Electronics Tech. I am somewhat "rusty" on my Electrical Code. I am trying to find out how many conductors can be within a 4x4x 1.5" junction box. What i want to put into the box is 3 pieces of romex of 12-2. Is the size junction box i have large enough to handle the three romex cables or will i have to go to a larger box??

The info you need is in 2005 NEC 314.16

Beyond that we can not help you.
