What is Electrical Enclosure?

Electrical Enclosure is a place where electrical or electronic equipment is housed. Its function is to safeguard individuals from the equipment while simultaneously protecting it from the environment (particularly in the case of outdoor electrical enclosures) (e.g. to prevent electric shock or the propagation of an explosion).

Benefits of Electrical Enclosure

The most common advantages of having an electrical enclosure are as follows:

Protection from water intrusion

To protect against precipitation, the enclosure must be somewhat watertight. Since condensation requires the entry of water as a vapor, it can be more difficult to solve than other typical issues. Flooding can be a problem in some circumstances, and many enclosures (with high IP ratings) can be inundated in water.

Protection against extreme low or high temperatures

Electronic equipment might become damaged or cease to function correctly under extreme temperatures. Adding ventilation (perhaps forced, with fans), double skins, insulation layers, or even air conditioning units to the enclosure is typically necessary to control temperature.

It is vital to take normal external temperature changes and solar gain into account when designing the heat management for an enclosure (heating from the sun). However, the electrical or particularly electronic equipment inside the cabinet can also produce a lot of heat.

Protection from risks and the durability of the cabinet

The electrical components inside electrical enclosures are typically the main source of risk. To keep individuals from getting into contact with these components is the enclosure’s main duty. The electrical components and wiring could become exposed and a shock hazard if the enclosure is broken.

Passively secure structures

The enclosure itself can also be dangerous, especially if it is placed next to a road where it might be struck by a car turning off the road. Roadside equipment is meant to shear off or collapse a collision, preventing serious injury to the car occupants, in a field of street furniture design known as passive safety.

There are numerous

varieties of signs, signals, and passively safe lighting. However, only one passively secure roadside enclosure—the Ritherdon passively secure cabinet—has been created.

Electrical Enclosure Types

Type 1

Type 1 enclosures are designed to prevent unintentional contact with enclosed machinery and are often used indoors, away from unique service circumstances.
It is an enclosure created with interior use in mind, providing the most fundamental level of security.

Type 2

Type 2 enclosures made for indoor use that offer some level of protection from
providing some level of protection for personnel against access to potentially dangerous areas, for the equipment inside the enclosure against entry of solid foreign objects (dropping debris), and the equipment from the damaging effects of water intrusion (dripping and light splashing).

Type 3

Type 3 enclosures are designed for outdoor use and primarily offer some kind of protection against external ice development, rain, sleet, and wind-blown dust. This enclosure has both indoor and outdoor use, respectively. They are primarily utilized as exterior electrical enclosures, though.
These enclosures can be used as outdoor electrical junction boxes to safeguard electrical wiring connections and cables, albeit they might not be appropriate for extreme weather conditions.

Type 3R

Type 3R enclosures are built for indoor or outdoor use to provide a degree of protection against personnel access to hazardous parts, a degree of protection for the equipment inside the enclosure against ingress of solid foreign objects (falling dirt), a degree of protection against harmful effects on the equipment due to ingress of water (rain, sleet, snow), and that will remain undamaged by the external formation of ice on the enclosure

Type 3S

Type 3S enclosures are built for indoor or outdoor use to provide some level of protection for personnel against access to hazardous parts, some level of protection for the equipment inside the enclosure against ingress of solid foreign objects (falling dirt and windblown dust), some level of protection against harmful effects on the equipment due to ingress of water (rain, sleet, snow), and for which the external mechanism(s) remain operational

Type 3X

Type 3X enclosures are built for indoor or outdoor use to protect personnel from access to hazardous parts, to protect the equipment inside the enclosure from ingress of solid foreign objects (falling dirt and windblown dust), to protect the equipment from harmful effects caused by the ingress of water (rain, sleet, snow), and to provide an additional level of protection.

Type 3RX

Type 3RX enclosures are built for indoor or outdoor use to provide a degree of protection against personnel access to hazardous parts. To provide a degree of protection for the equipment inside the enclosure against ingress of solid foreign objects (falling dirt). A degree of protection against harmful effects on the equipment due to ingress of water (rain, sleet, snow), and that will be undamaged by the external formation of ice on the enclosure.

Type 4

In both indoor and outdoor settings, Type 4 enclosures are designed to offer some degree of protection against wind-borne dust and rain, splashing water, hose-directed water during cleaning activities, etc.

Type 4X

Enclosures are designed to be used indoors or outdoors and are primarily used to give some kind of protection from wind-borne dust and rain, splashing water, hose-directed water during cleaning activities, and corrosion-resistant materials

Type 5

To some extent, enclosures are made for indoor use to give protection.
personnel from access to dangerous parts; to provide some protection for the enclosed equipment from an entry of solid foreign objects (falling dirt and settling airborne dust, lint, fibers, and flyings); and to provide some protection from damage caused by water intrusion (dripping and light splashing).

Type 6

Enclosures are built for indoor or outdoor use to provide a degree of protection to personnel against access to hazardous parts, a degree of protection for the equipment inside the enclosure against ingress of solid foreign objects (falling dirt), a degree of protection against harmful effects on the equipment due to the ingress of water (hose-directed water and the entry of water during occasional temporary submersion at a low elevation), and a degree of protection against harmful effects on the equipment due to the ingress of air.

Type 7-8-9 & 10

These enclosures are intended for usage in risky environments.

Type 11

Type 11 enclosures offer oil immersion of the apparatus, making them appropriate for use in applications where the equipment is exposed to vapors of acid or other corrosives.

Type 12

The main purpose of Type 12 enclosures is to offer some degree of protection against dust, falling dirt, non-corrosive liquids, and coolant seepage when used indoors.

Materials used in Electrical Enclosure

Electrical housings can be made of a variety of materials, which can have a big impact on how well they perform and function. Some of the most popular foundation materials used to make enclosures include the following:

Polycarbonate Plastic

Enclosures made of polycarbonate plastic offer great impact resistance and are typically less expensive than metal enclosures. Additionally, polycarbonate is very adaptable and suited for both indoor and outdoor uses. Due to its balance of cost and durability, it’s a good option for other non-metallic enclosure materials like PVC.

Polycarbonate Enclosures

are frequently utilized in desktop electronics and electrical instruments connected to the IT industry due to their comparatively inexpensive cost. They’re also a popular option for electrical applications that use non-metallic cable, though they can also be used with metallic cable if a ground wire is provided and correctly placed.

ABS Plastic

ABS, another well-liked substance for interior electrical boxes made of plastic, is acrylonitrile butadiene styrene. Even while ABS doesn’t offer the same durability as polycarbonate, it is still a sturdy material with high resistance to impacts and heat. ABS is often one of the more economical enclosure material options. As a result, it’s one of the most widely used kinds of electrical boxes for interior applications that need only the most minimal security.


Comparatively speaking, aluminum enclosures are more expensive than plastic enclosures. But they also provide some significant advantages of their own.

Aluminum is a very strong material that can tolerate high temperatures and is appropriate for both indoor and outdoor boxes. Aluminum alloys also provide natural EMI/RFI shielding to reduce interference and are very resistant to corrosion. Since a metal enclosure is typically required to ground the conduit, metal enclosure materials like aluminum are also crucial for applications that use metal conduit or metal sheathed cable.
Stainless Steel

Stainless steel enclosures

have benefits and drawbacks, just like most enclosure materials. Stainless steel is a heavy material that is typically more expensive compared to other enclosure materials, despite being fire-resistant and functioning well in moist situations. It is still a preferred material for metal boxes because of its great durability and appealing look, and it, like aluminum, can serve as a grounding agent for metal conduits and metal-sheathed cable.

Carbon Steel

Enclosures made of carbon steel are sturdy and affordable. They should not be utilized in coastal areas because of their high corrosion susceptibility, since the salt in the air can quickly corrode the enclosure unless a protective powder coating is added.

Common Applications for Electrical Enclosure

Here is the list of applications where the electrical enclosure is widely used:

Irrigation Wiring

To pump water from the source and sprinkle it on the grounds, irrigation uses electrical energy. You will need a dependable source of energy whether you want to water your farm, garden, or lawn. It will be important to have the right wiring set up to accomplish this. However, water will need to be kept out of the joints where the wires meet. The switches that will be used to turn the system on and off must also be weatherproof. Electrical enclosures will aid in safeguarding your investment and preventing electrocution for you.

Low Voltage Lighting

Accent lighting may enhance your home’s aesthetic appeal. The electrical equipment will undoubtedly be exposed to weather conditions when low-voltage lighting is put in an outside space. This means that the apparatus needs to be set up so that it is shielded from the sun, rain, and dust. Additionally, you need to take every precaution to prevent any visitors, children, and pets who might come into contact with dangerously exposed wires. The use of electrical enclosures is the best defense against accidents and property damage in your house.

Pool Installations

Your pool is functioning and maintained with a lot of electrical equipment to provide comfort while swimming. Pool installations are the term used most frequently to describe this equipment. However, there needs to be dependable energy to power the installations for them to function as planned. This implies that you will want skilled electrical wiring installation around the pool. The wiring should prevent water from reaching the exposed pool installation components and ensure that no exposed wires enter the pool. Swimming in the pool could result in injury or even death if the electrical current comes into touch with the water. This is the rationale behind the adoption of waterproof electric enclosures.

Water Docks

Your water dock most certainly has dock wiring to let you accomplish some tasks, depending on the model you have. Electrical wires and switches are certain to be present together with such wiring. There is a real risk of water getting into the equipment or coming into contact with cables on the pier due to the vast volume of water that surrounds these docks and the waves that raise them high above the surface. Electrical enclosures can be installed next to the dock to protect the dock wiring as well as to guarantee that no one using the dock or swimming in the nearby waters will get electrocuted.
Boat Applications
Any boat’s intricate systems depend on electricity to perform several different tasks. Boats are utilized on water, therefore any exposed portion of the circuit is likely to come into touch with water. If this occurs, the boat might not operate as intended or its occupants might get electrocuted. For this reason, it’s crucial to keep any boat applications dry and away from the water. For usage in such circumstances, watertight electric enclosures are available. Such box enclosures ought to be employed to keep the area secure at all times.

Other Outdoor Power

You should make sure that electric enclosures are erected wherever there is outside electricity so that the circuit is well-protected. This covers telecommunications tools and internet connections. Electrical box enclosures should be used to protect outdoor equipment and products from the weather.

Factors to Consider in Choosing the Right Electrical Enclosure

The following are the most crucial considerations when choosing an adequate electrical enclosure:

IP Ratings and Engineering Applications

The size and purpose of your electrical circuit are key considerations when choosing an electronic enclosure. Depending on the electronic requirements of your circuit and its technical applications, the design of electronic cabinets may alter. The requirements for Ingress Protection ratings (IP ratings) also play a significant role in the selection process because they specifically address the requirements for the level of protection against contact with live parts, damage control from mechanical impact, and other mechanical factors like the opening of water and other solid foreign objects.

Environmental Conditions

Making the right choice of an electronic enclosure requires knowledge of the operational environment and weather conditions to which the circuit will be subjected. Clarity on the enclosure’s intended location is essential, especially when selecting the appropriate material. The material and other requirements of an electronics enclosure can be determined based on whether the enclosure will be walled in indoor or outdoor spaces, exposed to harsh heat temperatures or chemical pollutants, or in extreme weather conditions.

Thermal Requirements

When selecting cabinets for delicate electrical components, thermal conditions and electronic circuit standards must be taken into account. This is yet another crucial factor that has a big influence on the material selection for electronic enclosures. Plastics work well as insulators and can be utilized to create casings for electrical circuits that don’t require a lot of heat dissipation. However, metallic enclosures may be more suitable for circuits with high voltage and high current demands, which may potentially reflect in very high power density and heat dissipation.

Industry Standards for Performance and Design

To define and develop industry standards for electrical, electronic, and associated technologies, governing organizations, international standard committees like the International Electro-Technical Commission (IEC), as well as government policymakers, and regulators, were involved. These specify the product requirements that must be met, and they must be taken into account while selecting the appropriate electronic enclosure.

Types of Materials

The availability of numerous types of materials to precisely meet the requirements for electronic enclosures in diverse applications has expanded thanks to recent developments in material sciences and technology. Price, size, weight, and aesthetics are other elements that could affect the material selection for electronic cabinets in addition to the thermal, electrical, and environmental criteria. One of the most economical window materials is acrylic. Acrylic is a common material choice since it is flexible, lightweight, and more impact resistant than glass. These factors combined with its lighter weight make acrylic one of the most popular alternatives.

Cost of Ownership Overall

Making the best choice of electronic enclosures requires an understanding of the value of cabinets, which is mostly based on the cost of acquisition as well as ongoing running and maintenance expenses. By taking into account the potential maintenance and downtime costs associated with various kinds, which ultimately affect TCO, an optimal enclosure can be chosen.

Size of Equipment

This is one of the most fundamental yet crucial considerations that must be made while selecting the right enclosure. Although smaller enclosure sizes are favored in contemporary electronic equipment, the depth of the finished product must be taken into account when choosing a cabinet to make the installation procedure more practical and convenient. Additionally, the size of the electronic enclosure needs to allow for proper power distribution and cable management in the circuit.

Adaptability to Design

The enclosure should provide adequate flexibility in terms of depth, height, and width based on the circuit’s design. Additionally, the enclosure should be adaptable enough to incorporate different controls for routers and other IT equipment with the emergence of sophisticated technologies like information technology (IT), big data, and the internet of things (IoT).

Electromagnetic Compatibility

The issue of electromagnetic interference (EMI) has emerged as a major worry due to the increasing use of innovative technologies and the current electronic gadgets becoming faster than ever. As EMI becomes a more common problem, it is necessary to choose an enclosure that can provide EMI protection while using equipment in EMI-containing situations.

Future Modification Potential

It is likely the most crucial aspect that must be taken into account when selecting an electrical enclosure. When choosing a cabinet for your equipment, consider the possibilities for modification and cutouts for a variety of reasons, such as adding a weather control to the roof, making room for a Human-Machine Interface (HMI), or adding a cable entry.


As the ambient temperature can undoubtedly affect the operation of the equipment enclosed within a cabinet, it is important to take into account where the enclosure will be put. You should be aware of the equipment’s temperature tolerances as well as the minimum and maximum acceptable ambient temperatures.


With the development of technology, we are beginning to use electrical equipment in a range of unconventional settings. Selecting the appropriate electrical enclosure for the application at hand is essential to ensuring sufficient protection of electrical components.
