Industrial Junction Box or Enclosure - How to select the correct enclosure

Enclosure selection must be based on the industrial purpose, location and environment.  Of course, most industrial factories and large facilities might have hundreds, or possibly thousands of critical electrical power & network signal connections that require dustproof, waterproof and submersible protection from indoor dust or harsh outdoor environmental conditions including submersion from overflow storm water. Therefore  engineers and maintenance crews should the selection on the actual enclosures and how often they need access the equipment.  Nemaco offers many different types of performance class junction boxes, enclosures  and cabinets to protect electrical equipment. The enclosures are designed to safeguard everything from communication cables to splicing standard solid-wire and multi-strain wires in outlet boxes to large cabinets.  Nemaco offers waterproof electrical junction boxes that are durable and provide long-lasting performance in any environmental or industrial setting including heavy moist humidity, soggy wet storm rain, or including submersion underwater environments.

Here's the key quality & performance factors for submersible enclosures:

  • Enclosures must be strong & durable for any industrial environment: water, tools and boots.
  • Enclosure must be Stainless Steel, heavy wall Aluminum or heavy duty FRP Fiberglass.
  • Gaskets must be designed and tested for icy cold temperatures to 400 degrees Fahrenheit

Standard Materials & Protection Ratings forSubmersible Junction Boxes & Enclosures

There are industry standards for performance classwaterproof submersible enclosures for industrial applications. The enclosures must be fabricated fromstrong materials and not cheap plastic designs that will be prone to be easilydamaged in most industrial environments. Projects engineers and designers shouldspecify only strong, heavy duty waterproof enclosures with quality durablegaskets.

Waterproof Submersible Enclosure - Key Specifications

  • Heavy-duty materials: stainless steel, heavy wall aluminum and FRP (fiberglass).
  • Gasket Seal: Flame resistant UL Listed Silicone Rubber design for cold & hot environments
  • NEMA 6, 6P and IP67, IP68-Rated for application & depth of submersion

Waterproof Submersible Enclosure Applications

Waterproof enclosures fulfill a wide range of purposes. They can guard sensitive electronic equipment, or they might serveas electrical outlet boxes or electrical junction boxes inharsh environments. Many are designed to work as either indoor or outdoorelectrical boxes, with features that allow them to excel in either role. Anywhere that water hazards such as wet weather or hose spray threatenelectrical and electronic equipment, waterproof enclosures are must-haves.

NEMA 4X vs NEMA 6P (IP67,IP68) Waterproofing Comparison

There are other forms of waterproofing options for example NEMA4X enclosures that are manufactured primarily from stainless steel. The NEMA 4X enclosure are rated from waterspray resistance but not water submersion. NEMA 4X enclosures are useful and provide protection for most electricalswitch gear and telecommunication network server rack applications. Sometimes customers prefer NEMA 6P (IP67,IP68) enclosure and junction boxes because the enclosure materials and design construction provide better sealing capability then the NEMA 4X rating. TypicallyNEMA 4 / 4X enclosures have softer seals (closed cell foam) and the NEMA 6P (IP67,IP68) gasket seal are solid rubber. Therefore the hard rubbers are more durable for all applications.Therefore, customers prefer the submersible enclosure designs since theenclosures provide more water resistance and much more protection for criticalelectrical equipment and network systems.

Enclosure Customization & Hardware Options

Nemaco can offer the following hardware and water sealingoptions for customers.

  • Conduit Hubs (NPT, FPT, FF, etc.)
  • Cable Glands (NPT, Jam Nut Design)
  • Piping & Fittings (Misc. pipe connections)
  • Door Floating Hinges (for NEMA 6P Enclosures)
  • Roxtec Industrial Seals (NEMA 4, 4X, 6, 6P)
  • Alternate Gasket Solutions (for other chemical resistance)
  • Door Screw Captive Hardware (for bolts)
  • Clear Windows (for non-UL applications)
  • Dual Rated N6P-N4X Seals for Enclosure & Cabinets
