Buying Guide
Key purchase considerations
- Dimensions and fit: Ensure the internal clearance matches the equipment you plan to install. Variations around 16×16 inches are common, but actual internal dimensions can differ.
- Material and durability: Steel enclosures deliver high strength and vandal resistance; ABS plastics offer lighter weight and corrosion resistance. Choose based on exposure, impact risk, and weight constraints.
- Waterproofing and sealing: Look for IP ratings (IP65, IP66, IP67) and sealing strips or gaskets that resist dust, water, UV exposure, and temperature cycling.
- Hinges, locks, and hardware: Reinforced hinges and robust lock cores improve long-term security. Stainless steel hardware often resists corrosion better in harsh environments.
- Mounting options: Check for backplanes, pre-drilled holes, mounting plates, and wall brackets to ensure straightforward installation and stability.
- Accessibility and maintenance: Consider enclosure access, lid design, and whether components can be serviced without removing the entire box.
- Code compliance: Confirm compliance with local electrical codes and any industry standards that apply to outdoor or industrial installations.
Material comparisons
- Steel enclosures provide superior rigidity and durability against impact and corrosion when coated or treated. They’re ideal for demanding outdoor use.
- ABS plastic enclosures are lighter and resist corrosion and chemicals; they’re often preferred for indoor or less aggressive outdoor environments.
- IP ratings indicate protection levels against ingress; higher ratings generally translate to better weatherproof performance but may come with higher costs or increased weight.
Installation considerations
- Plan wall placement to minimize exposure to direct sun and extreme temperatures that can affect seals and plastics.
- Ensure cable entries and knockouts are sized for your cables and that knockouts are properly sealed after installation to maintain IP rating.
- Maintain a clear open area for hinges and locks to prevent bending or jamming due to debris or accidental impact.
