Issac,
Those big grey boxes are known as NEMA enclosures. They are usually fiberglass reinforced and meet a lot of safety standards for electrical enclosures. You might find some at Mouser or Digikey. BTW Digikey now supports a team in Minnesota.

Isaac,

There are several types of these enclosures. In a theatrical type environment you likely would not need a sealed water tight enclosure. A type I enclosure would be fine. This will help to reduce the cost, although they are still expensive. Attached is a data sheet showing some that I like to use. Also attached is a sheet showing the heavier type 12. You can find more on their website. The window is an option.

As mentioned previously Hoffman is the standard. Contact any electrical supply house in your area. They will be happy to help you. The first question would be if they carry Hoffman enclosures. If not then go on to the next vendor.

Love the fact you are combining robots and theater. We used a holo mic drive robot base to animate a piece of furniture for Blithe Spirit a couple years ago. Took home a Technical Design award for that show. About to start production on Something's Afoot which will also include a robotized piece of furniture and some magic components.

The enclosures are usually just sheet metal boxes and come in a variety of shapes and sizes i believe the ones on the field are Allen-Bradley but i may be mistaken you could find them at your local industrial supply company or electricians supply company.
