Electrical Enclosures are boxes or a cabinets that house electrical equipment and are designed to protect both workers and sensitive components from potential electrical hazards. Enclosures can be made from metals, such as steel, stainless steel and aluminum, or rigid plastics. Electrical enclosures must operate under extreme environments in various industrial settings. Some things to consider when selecting the appropriate enclosure: strength, heat tolerance, corrosion resistance, ease of fabrication and affordability. Steel Enclosures have a higher carbon content than stainless steel, which results in a relatively high yield strength, but lower tensile strength. It also requires additional finishing (paint or powder coating) to prevent corrosion. Steel enclosures tend to be more affordable than stainless steel enclosures.
