❓ Frequently Asked Questions
How to choose the IP protection level of Outdoor Distribution Boxes?
IP65: Completely dustproof, can resist low-pressure water spray.
IP66: Resistant to high-pressure water spray (heavy rain scenarios).
IP67/IP68: Short-term immersion or long-term underwater protection.
Selection suggestions: Choose IP66 or above for coastal areas, and prioritize IP65 for dusty environments.
How to ensure sealing during outdoor installation?
1. Use waterproof cable glands (PG/NPT thread) with waterproof mastic.
2. Use double-layer silicone sealing rings with a labyrinth waterproof structure.
3. Reserve drainage holes at the bottom or use an inclined top cover (≥5°).
How to balance sealing and heat dissipation?
You can install a breather valve to adjust internal/external air pressure while remaining waterproof. For high-load components, forced heat dissipation solutions like temperature sensors linked with cooling fans are recommended.
What maintenance is required for outdoor boxes?
Check the sealing ring elasticity and clean vents quarterly. Test grounding resistance annually and tighten all screws. In coastal areas, clean surface salt deposits every six months to prevent corrosion.
Can these boxes be used in highly corrosive environments?
Yes, while the standard material is high-quality steel plate, for highly corrosive or coastal environments, we recommend specific surface treatments or stainless steel variants to ensure long-term durability.
Are custom sizes available for specific project requirements?
The standard model shown is 500-400-200mm, but the structural design allows for modifications in dimensions and internal mounting plate configurations to accommodate different electrical components.
