Creating a superior cathodic protection system starts with selecting the right electrical components. This includes choosing an electrical junction box which is best suited for a particular corrosion prevention application. Because there are so many unique applications for cathodic protection, MESA offers custom junction boxes which are made according to design specifications. A custom junction box can be manufactured according to operating parameters, or to exact design specifications.

Junction boxes are installed in all types of environments. To provide adequate protection from the elements, an appropriate enclosure should be selected. MESA custom junction boxes are available with all the common electrical cabinet materials including fiberglass, aluminum; and stainless painted, or galvanized steel. The cabinets may be selected to meet and of the NEMA enclosure standards, from dust tight to explosion proof and are offered in numerous sizes to accommodate different circuit configurations.
