A Electrical Box is a container in the Fallout: New Vegas DLC Old World Blues.
Gameplay
These containers can be looted for Scrap Metal, Scrap Electronics, Sensor Modules, and Drained Small Energy Cells. The only difference between the low and Med variant is that the latter provides more chances to get scrap electronics and metal.
Locations
Both variants are found around the Big MT, though a few Med variants can be found inside The Forbidden Zone Dome, and X-13 Research Facility.
