In the first perusal, electrical enclosures may not seem to be very crucial. But these carefully engineered boxes serve a vital role in protecting electronics in industries like I.T. Systems, telecommunications, utilities, etc.
With advancing technology, the role of innovative indoor and outdoor enclosures is more vital than ever. Selecting the right kind of enclosure can help to save not only lives but also millions of dollars relating to operating costs and equipment.
ERNTEC sells outdoor enclosures like steel enclosures. The company manufactures strong cabinets made of aluminium, stainless steel, galvanized steel, and mild steel.
The challenge facing design engineers is which electrical enclosure is best for their unique application. While discussing kinds of electrical enclosures, most professionals refer to enclosure types as defined by the National Electrical Manufacturers Association (NEMA).

The challenge facing design engineers is which electrical enclosure is best for their unique application. While discussing kinds of electrical enclosures, most professionals refer to enclosure types as defined by the National Electrical Manufacturers Association (NEMA).
NEMA defines the North American standards for electrical enclosures. These ratings indicate the ability of an electrical enclosure to endure specific hazards and environments. The following are the major kinds:
They are designed for indoor uses and offer the least amount of protection. They offer a degree of protection against dirt, dust as well as accidental contact with electrical equipment.
They are fashioned for both outdoor and indoor use. But mostly they are used as outdoor electrical enclosures. The reason is that they protect against falling snow, rain, dirt, sleet as well as the formation of external ice. Though not suited to extreme conditions of weather, they can function as outdoor electrical junction boxes for protecting cables and wires.
These protect against harsher weather conditions. Also, they have watertight features which render them ideal for industrial applications like protection of outdoor wiring systems.
It offers the same level of protection as NEMA 4 but has more capacity to resist corrosion.
It is designed for both outdoor and indoor use as it is mostly used for applications that have temporary submersion in water. Such waterproof electrical boxes are found in uses like maritime transport.
They provide the same level of protection as the previous type, but permit prolonged submersion in water and have extra protection against corrosion.
They are built for indoor hazardous locations like atmospheres containing explosion causing inflammable gases.
Used for indoor applications and protect against dust, dirt, and water drips.
Other Types of Enclosures
They are less costly than metal enclosures and have tremendous impact resistance. They are also highly versatile and suit a wide range of outdoor and indoor applications.
It is more expensive. But it offers some important benefits. It is highly durable and can endure high temperatures. Alloys of aluminium are also highly corrosion-resistant.
There are pros and cons to stainless steel enclosures. They are fire-resistant and perform well in a wet environment, but they are heavy and more expensive. You can find the best quality steel enclosures at ERNTEC.
They are cost-effective and strong, but they are highly prone to corrosion and must be avoided in coastal areas with salty air.
In sum, with the progress of technology, electrical equipment can be placed in many non-traditional environments. It is critical to select the right enclosure for the application in hand so that electrical components are adequately protected.
- NEMA 1
They are designed for indoor uses and offer the least amount of protection. They offer a degree of protection against dirt, dust as well as accidental contact with electrical equipment.
- NEMA 3
They are fashioned for both outdoor and indoor use. But mostly they are used as outdoor electrical enclosures. The reason is that they protect against falling snow, rain, dirt, sleet as well as the formation of external ice. Though not suited to extreme conditions of weather, they can function as outdoor electrical junction boxes for protecting cables and wires.
- NEMA 4
These protect against harsher weather conditions. Also, they have watertight features which render them ideal for industrial applications like protection of outdoor wiring systems.
- NEMA 4 X
It offers the same level of protection as NEMA 4 but has more capacity to resist corrosion.
- NEMA 6
It is designed for both outdoor and indoor use as it is mostly used for applications that have temporary submersion in water. Such waterproof electrical boxes are found in uses like maritime transport.
- TYPE 6P
They provide the same level of protection as the previous type, but permit prolonged submersion in water and have extra protection against corrosion.
- NEMA 7
They are built for indoor hazardous locations like atmospheres containing explosion causing inflammable gases.
- NEMA 12
Used for indoor applications and protect against dust, dirt, and water drips.
Other Types of Enclosures
- Polycarbonate Plastic
They are less costly than metal enclosures and have tremendous impact resistance. They are also highly versatile and suit a wide range of outdoor and indoor applications.
- Aluminium
It is more expensive. But it offers some important benefits. It is highly durable and can endure high temperatures. Alloys of aluminium are also highly corrosion-resistant.
- Stainless steel
There are pros and cons to stainless steel enclosures. They are fire-resistant and perform well in a wet environment, but they are heavy and more expensive. You can find the best quality steel enclosures at ERNTEC.
- Carbon steel
They are cost-effective and strong, but they are highly prone to corrosion and must be avoided in coastal areas with salty air.
In sum, with the progress of technology, electrical equipment can be placed in many non-traditional environments. It is critical to select the right enclosure for the application in hand so that electrical components are adequately protected.
