I've got a "Lame Californian" Q.
I see the padlockable closure at the bottom of this can. Are these things openable?? All of our meter bases are mounted to the back of the box. The cover is held on by a screw in the center of the meter area. One has to remove the meter to take the cover off.
Our resi services come with meter, main, and branch c/b's in one enclosure and are called "combination services".

This shot adds a completely new depth and meaning to the term "combination service"
