An electrical enclosure box serves a vital role for any property, be it a residential home, a commercial space, or a large factory. If you are in need of an enclosure box, careful thought and planning will help you find the best fit for housing your electrical equipment and connections.
What is an Electrical Enclosure Box?
An enclosure box safely contains electrical equipment, including circuit breakers, sensitive electrical devices, and other related equipment. On occasion, it is also referred to as an electrical box, junction box, or breaker box. The enclosure box is a simple yet reliable storage compartment that shields electrical components from various environmental hazards, including moisture, temperature fluctuations, chemicals, and physical damage. You can find these enclosures in multiple forms that meet specific requirements across different environmental conditions.
Types of Electrical Enclosure Boxes
Metallic Enclosures
Made from durable metals such as stainless steel and aluminium, these enclosure boxes offer significant durability from physical harm as well as impressive corrosion resistance. These properties make them suitable for most residential, commercial, and industrial settings.
Non-Metallic Enclosures
These enclosure boxes are made of non-metallic materials, including polycarbonate and fibreglass. Lightweight and cost-effective, these are typically used indoors, where the boxes are not exposed to various environmental factors that could compromise their electrical contents.
Custom-Built Enclosures
Some enclosures may require custom-built solutions based on unique specifications to meet specific regulatory standards or use cases. These are not often seen, except in particular settings where standard metallic or non-metallic enclosure boxes are unable to adequately shield the stored electrical components from harm.
Essential Considerations For Your Electrical Enclosure Box
Materials & Durability
The right materials can ensure the enclosure box sufficiently shields its contents from damage, whether due to moisture, chemical exposure, or physical harm. Aluminium is a common material used for its low cost, decent durability, and impressive corrosion resistance, making it ideal for homes and commercial buildings. Stainless steel affords substantial protection and a sturdier build, but can be fairly expensive. Meanwhile, non-metallic materials are non-conductive to protect against potential electrical faults, but may not be very resistant to physical damage.
Size and Dimensions
Considering how businesses may need to upgrade existing equipment, vital considerations regarding an enclosure box’s size can be necessary to prepare for future additions to your electrical infrastructure. As such, prudent positioning of the enclosure box ensures there is sufficient space for expansions and can also facilitate smoother maintenance cycles when replacement parts are needed. Custom-built boxes may be the ideal option for very specialised needs.
Installation & Maintenance
If you or your team are capable of setting up an enclosure box, consider opting for one with clear instructions on how to install and maintain it throughout its use. Once it reaches its end of life, easy removal procedures can also make enclosure replacements much easier. It helps to plan an optimised layout to maximise internal space for current equipment and future expansion. If you need a box for small, tight spaces, measure your space twice to ensure you purchase an accurately measured enclosure box.
Environmental Ratings & Compliance
There are two core environmental ratings to consider. Specific environments or use cases may require particular ratings, as outlined by local or international regulatory requirements, to ensure the enclosure box is safe for use. Adhering to these standards is mandatory for general health and safety.
Ingress Protection (IP)
This rating system, monitored by the International Electrotechnical Commission (IEC), measures an enclosure box’s protection against foreign objects and liquids. It employs a two-number rating system: the first number reflects the protection level against solids, while the second number represents the protection level against liquids.
National Electrical Manufacturers Association (NEMA)
This separate enclosure rating system defines a box’s protection against other factors not covered by the IP system. This includes physical damage, corrosion, and even watertightness.
Additional Certifications
Certifications by other professional or government bodies ensure that an enclosure box has been rigorously tested and meets set standards that attest to the box’s overall quality.
Cost vs. Value
High-quality enclosure boxes are built to last and can come with hefty price tags. However, the value proposition that a well-built enclosure provides makes it a good investment, especially considering its high build quality, ratings, certifications, and regulatory compliance.
Be mindful of an enclosure box provider’s credentials and quality, as a professional technical team and enclosure box can ensure a smooth-sailing, high-quality installation. You can also be assured that maintenance cycles will be conducted to rigorous standards.
