FAQ:
1. Does it matter if you use a plastic or metal electrical box for outdoor use?
Yes, it matters for outdoor scenarios. BSUMWELL’s plastic cable junction boxes (made of high-quality new ABS material) have distinct advantages for outdoor use: they are lightweight, corrosion-resistant (suitable for humid/rainy environments), and have a temperature tolerance of -20℃ to +80℃. Metal boxes, by contrast, may rust over time outdoors and are heavier, increasing installation difficulty. Additionally, BSUMWELL’s plastic boxes meet IP55/IP65 waterproof/dustproof standards and CE/ROHS certifications, ensuring compliance with outdoor electrical safety requirements.
2. How to waterproof outdoor electrical connections?
To waterproof outdoor electrical connections, we recommend two key steps:
Use a dedicated outdoor waterproof junction box (e.g., BSUMWELL’s IP55/IP65-rated plastic boxes) to enclose the connections—these boxes come with PVC dustproof plugs to seal gaps and prevent rain/dust intrusion.
Ensure the box is properly installed: align the box’s mounting holes with outdoor fixtures, tighten screws to avoid loose seams, and avoid installing the box in low-lying areas where water may accumulate. For extra protection, you can wrap the box’s wire entry points with waterproof tape (compatible with the box’s ABS material).
3. How to run a small wire into a waterproof enclosure?
Follow these simple steps to run small wires into BSUMWELL’s waterproof enclosure:
Select the appropriate hole on the box (matching the wire diameter; refer to the “Hole Diameter” column in the product specification table, e.g., 25mm or 36mm holes).
Remove the PVC dustproof plug from the selected hole, pass the small wire through the hole, and strip the wire ends (if needed for connection).
After wiring, reinsert the PVC plug around the wire to fill the gap—this maintains the box’s IP waterproof rating. The box’s internal mounting posts also help fix the wire or terminal blocks, preventing wire displacement.
4. Can a junction box be plastic, and is it suitable for outdoor electrical projects?
Absolutely—plastic junction boxes are not only usable but also ideal for outdoor electrical projects, especially BSUMWELL’s plastic models. They are designed for outdoor use:
Compatibility: Suitable for outdoor projects like garden lighting, CCTV power connections, or shed electrical wiring. BSUMWELL also supports customization (e.g., adjusting hole positions) to fit specific outdoor project needs, and offers quick delivery with stock availability.
