Electrical Enclosures
Electrical enclosures serve to keep electrical and electronic equipment safe from environmental variables that could cause them to fail. These enclosures have to be tough, and the materials chosen for their construction are typically steel, aluminum, or polycarbonate. These materials and the way they can be formed and finished make these enclosures appropriate for the kind of harsh conditions that might otherwise threaten the operation of an electronic device. "Harsh" could include anything from extreme temperatures to precipitation to the kind of dirt and dust you might encounter even in outdoor applications—but these enclosures are also made to keep the electronic components inside safe from anything in the environment that might threaten their safety and operation.
In industrial environments, an electrical control box performs a vital role in protecting equipment and ensuring that it remains operational. A custom enclosure allows for specific application details, such as size and material configuration, to be accommodated. These cabinets are built to withstand a range of industrial and commercial environmental conditions, providing a robust solution for both indoor and outdoor placement. Extra features like secure locks and panels help diminish the likelihood of any equipment shut-down catastrophes.

FAQs
Is it possible to find a full line or wide selection of electrical enclosures with accessories that are specifically designed for the oil and gas industry where security is critical?
Yes, it is possible to find a full line of electrical enclosures with accessories specifically designed for the oil and gas industry, offering enhanced security and protection in critical environments.
Enclosure Selection Basics
Electrical enclosures or electric cabinets are designed to house electrical components. Their main function is to protect the components, as well as to protect the operators from electrical hazards. Enclosures are typically made of solid plastics, fiberglass and metal materials, such as carbon steel, stainless steel and aluminum. These materials ensure that the enclosures can withstand harsh environments, protecting the components inside from various external factors.
One of the most important things to consider when selecting an electrical enclosure is the NEMA rating. NEMA stands for National Electrical Manufacturer Association. They have developed a rating system which determines the types of environments an electrical enclosure can be used in.
NEMA 1 and a NEMA 12 enclosures
Both of these enclosures are intended for indoor use only. They are both dust resistant. The NEMA 12 enclosure is rated for damp environments. The NEMA 1 is rated only for dry environments.
NEMA 4 and NEMA 4X enclosures
Both of these enclosures can be used indoors as well as outdoors. They are both dust resistant. They are also water resistant and corrosion resistant. NEMA 4X has an extra layer of corrosion resistance. In addition to these, hazardous location enclosures are designed to protect electrical controls in areas prone to explosions or other hazards.
NEMA 7 enclosures
This is a more specific type of enclosure that is rated for use in hazardous environments. It is rated to contain an explosion within the enclosure and not cause any sort of external hazard.
Size
When selecting the size of an enclosure, it is important to consider the following: how much space will the electrical components occupy, how much space is needed around each component, is there enough room to run all of the wires and how much space is needed outside of the enclosure?
Temperature
When selecting an enclosure, it is important to consider both the ambient temperature and the temperature that is generated inside of the enclosure. When an enclosure is located outside in direct sunlight, that heat can be transferred inside the enclosure. Also, each component inside of the enclosure generates a certain amount of heat.
