Typically these structures house medium and low voltage Switchgear or Switchboards, MCCs, distribution panels, and other control structures. Virtually all Power Distribution Centers have a climate control system with heating and cooling based upon the environment and heat loading within the building. MCM Engineering II can construct these structures with standard steel, stainless steel, structural aluminum, and Galvaneal metals.
