Buying Guide: Non-Metallic Enclosures — What To Consider
Material matters. Non-metallic enclosures like ABS and UPVC or UV-rated plastics resist corrosion, minimize heat conduction, and keep electronics insulated. Size and mounting options should match your device footprint and installation space. IP and NEMA ratings indicate how well enclosures resist water, dust, and impact in real-world conditions.
What rating do you need?
IP ratings measure ingress protection for dust and water. IP65 means dust-tight against most dust and protected from water jets, good for outdoors. IP67 allows immersion in water up to 1 meter, ideal for harsh weather. NEMA ratings assess performance in different climates and mounting scenarios; higher numbers typically indicate stronger protection.
Is size important?
Choose a box that accommodates your equipment with space for wiring, cable glands, and future upgrades. Allow for ventilation or heat dissipation if your devices generate heat inside the box.
How important is accessibility?
Lockable latches, padlock compatibility, and hinged or easy-access doors improve security and maintenance. Consider whether you need quick access for inspections or routine wiring checks.
What about installation features?
Look for mounting plates, cable glands (NPT sizes), and included brackets. Quick-release hinges and robust latch hardware can simplify long-term use and reduce maintenance time.
FAQ
What is the difference between IP67 and IP65 in outdoor enclosures?
IP67 provides immersion protection up to 1 meter for 30 minutes, while IP65 protects against water jets. IP67 is better for environments with heavy rain or temporary submersion risks.
Are ABS plastic enclosures suitable for outdoor weather?
Yes, ABS is durable and UV-resistant in many models. It is preferable for light to moderate outdoor exposure and insulated electronics, but ensure the rating matches your climate.
Can non-metallic enclosures support high-amp disconnects?
Non-metallic enclosures generally support many disconnects, but ensure the material and mounting meet safety standards for your amperage and installation. For high-access disconnects, metal boxes can offer extra rigidity.
How do I choose the right size for a junction box?
Measure all components, wiring, and terminals. Add space for cable glands and future expansions. A box that’s too tight complicates wiring and heat management.
What maintenance is required for non-metallic boxes?
Regularly check seals and gaskets for wear, inspect for cracks after impacts, and ensure latches remain secure. UV-rated plastics resist sun damage with proper models.
Do non-metallic enclosures provide electrical insulation?
Yes, most ABS and UV-rated plastics offer good electrical insulation properties, reducing stray current risks and improving safety for exposed wiring.
