When it comes to protecting electrical and electronic systems, selecting the right enclosure is only part of the equation. Electrical boxes and enclosures protect wiring, switches, outlets, and electronic equipment from damage, weather, and environmental hazards.
To achieve peak safety, efficiency, and accessibility, it’s also important to choose the appropriate mounting accessories. Whether you’re installing equipment in an industrial facility, utility space, or outdoor setting, the right accessories can significantly enhance performance and reliability.
1. Consider the Enclosure Type
Every enclosure type is designed for a specific need and purpose. Likewise, the accessories should reflect those differences. Material compatibility, space constraints, and design elements impact how the components will perform.
- For polycarbonate enclosures, it’s best to use non-metallic or corrosion-resistant accessories to avoid material incompatibility.
- When working with clear or hinged cover boxes, look for accessories that compliment the quick internal access or easy visual inspection.
- Deep enclosures should be paired with rails or panels to maximize the usable internal space for larger or more complex setups.
2. Review Material Compatibility and Any Weight-Bearing Considerations
When installing internal components, it’s not just about where things go — it’s about whether the enclosure and accessories can support them. Both material compatibility and structural integrity are critical to ensuring long-term reliability. Keep the following points in mind to avoid premature strain or failure:
- Always check load ratings for each accessory
- Use enclosures with reinforced mounting bosses
- Select metallic panels or rails for heavier components
- Match polycarbonate accessories with polycarbonate enclosures to maintain insulation and corrosion resistance
3. Think About the Location of Your Enclosure
It’s important to consider the environment of your installation. Exposure to the elements, moisture, and temperature extremes can all impact long-term performance. Be sure to account for:
- Outdoor or UV Exposure: Use UV-stabilized polycarbonate or stainless steel brackets to withstand exposure to sun and weather.
- High Humidity or Washdown Areas: The corrosion resistance properties of stainless steel are ideal for environments where moisture or harsh cleaning chemicals are present.
- Extreme Temperatures: Select materials with similar thermal expansion rates to prevent stress damage from temperature fluctuations.
Why Accessories Are Essential for Electrical Boxes
Mounting accessories secure both external and internal components and play a key role in optimizing the overall system by:
- Improving internal component organization
- Protecting internal wiring, switches, and electronic equipment from damage and environmental hazards
- Reducing wear and stress on the enclosure
- Supporting long-term system reliability and ease of maintenance
- Maintaining compliance with safety and installation standards
What Are the Different Mounting Accessory Options?
Knowing the various functions and types of mounting accessories and selecting the right one can have a direct influence on the performance and protection of your system. Here are the most common options and what each offers:
Mounting Brackets
Used to mount your enclosure to the wall or other flat surface, these brackets provide strong external support. Available in polycarbonate or stainless steel, to meet your application and environment.
Back Panels
Back panels offer a secure base for mounting internal components such as relays, circuit breakers, and terminal blocks. Choose from steel, aluminum, or non-metallic materials to balance conductivity, weight, and corrosion resistance.
DIN Rails
DIN rails are essential for modular and scalable setups. They allow standardized, tool-free mounting of control and automation components and are ideal for organized, serviceable systems.
Common Accessory Selection Mistakes
Even with the right enclosure and components, small mistakes in accessory selection can lead to major issues, from equipment failure to safety hazards. Many of these problems are easy to avoid with careful planning and awareness. Below are some of the most common missteps to watch for:
- Installing metal panels in non-metallic enclosures without proper grounding can lead to electrical hazards and equipment damage.
- Overloading back panels without checking weight capacity may lead to structural failure or mounting issues.
- Choosing accessories that aren’t compatible with the enclosure’s size or depth can impact functionality and complicate maintenance.
- Ignoring heat dissipation and spacing for DIN-mounted devices can cause overheating and premature failure.
- Using hardware that lacks proper environmental protection increases the risk of corrosion and shortens your installation’s usable lifespan.
Get the Most from Your Enclosure with the Right Mounting Accessories
When selecting accessories for your enclosure, don’t just ask what fits — think about how it needs to perform. Consider your installation environment, internal component weight, and material compatibility. Done properly, your enclosure will provide reliable protection, simplified maintenance, and long-lasting performance.
