The NEMA box is a Radio Shack "Project Box". It's plastic and has a screw on cover.

There is a piece of Starboard mounted in it and the terminal board screw's to that. It get's it out of the bottom of the box to work on easier. Terminal strip was from Radio Shack too. There are hole's drilled in the box to match the grommet size needed for the particular wire size. Small tye wrap's on each side of the grommet's to act as a strain relief.
