Industry news
Ordering a custom Waterproof Junction Box or Waterproof Distribution Box ensures that your electrical system is safe, efficient, and reliable, even under unique conditions. By specifying size, material, IP rating, internal layout, and additional components, you can create an enclosure that ideally meets your needs.
Unique Size and Layout Requirements
Standard boxes may not accommodate all wiring, terminals, or additional components such as surge protectors or circuit breakers. Custom boxes allow engineers to define exact internal layouts, mounting points, and spacing for efficient organization and future expansions.
Environmental and Operational Conditions
Outdoor installations, industrial plants, or high-humidity areas may require enclosures with higher IP ratings, specialized gaskets, or corrosion-resistant materials. Custom boxes ensure reliable protection in extreme conditions, whether exposed to rain, dust, chemicals, or temperature fluctuations.
Integration of Additional Components
Some projects require pre-installed components such as terminal blocks, DIN rails, relays, or cable management systems. Custom junction boxes can be configured to include these components, reducing installation time and ensuring proper placement.

Define Project Requirements
Clearly specify the number of circuits, voltage levels, internal dimensions, mounting type, and environmental conditions. Include details about wire sizes, load, and future expansion plans to ensure the box meets operational demands.
Select Material and IP Rating
Choose the appropriate material—polycarbonate, ABS plastic, aluminum, or stainless steel—based on environmental exposure and mechanical stress. Select the IP rating that matches water, dust, and debris protection needs.
Provide Design Specifications
Share CAD drawings, sketches, or sample boxes to communicate design expectations. Precise specifications allow the manufacturer to produce an enclosure that fits ideally and meets technical standards.
Manufacturer Consultation
Collaborate with the engineering team at Pulte Electric Technology (Wenzhou) Co., Ltd. to optimize design, layout, cable entry, and sealing. Experienced engineers can recommend solutions that improve reliability, simplify installation, and maintain safety compliance.
Prototype and Testing
Request a prototype or sample unit for verification. Test for fit, accessibility, cable entry sealing, and environmental performance. Adjustments can be made before full production to ensure good functionality.
Final Production and Delivery
Once approved, the manufacturer produces the complete batch according to the custom specifications, ensuring consistency in quality, performance, and IP protection.
Proper Gasket and Seal Placement: Ensure all gaskets are correctly seated and lids are evenly tightened to maintain waterproof performance.
Cable Management: Use compatible cable glands and ensure no loose or oversized entries compromise the IP rating.
Regular Inspection: Periodically check gaskets, screws, and internal wiring, especially in harsh environments or high-traffic areas.
Future Expansion Planning: Leave room inside the box for additional wiring or components to facilitate upgrades without requiring a new enclosure.
Safety: Properly designed enclosures reduce the risk of short circuits, water ingress, and electrical faults.
Efficiency: Pre-configured layouts and integrated accessories save installation time and labor costs.
Reliability: High-quality materials, precise IP ratings, and secure cable entries ensure long-term durability.
Flexibility: Custom boxes can accommodate future expansions or modifications without requiring major rework.
