Compared With The Alternatives
| Compared With | How This Product Differs |
|---|---|
| Metal junction box | Metal boxes conduct electricity and rust in damp conditions. This plastic box is non-conductive and corrosion-resistant, making it safer and longer-lasting in wet environments. |
| Standard plastic junction box | Standard plastic boxes may not have a sealed design or proper gasketing. The RA series is built for waterproof performance, not just basic enclosure. |
Use Guide
- Mount the box on a clean, dry surface before connecting wires
- Use the appropriate cable glands or seals for each entry point to maintain waterproofing
- Ensure all cable entries are tight and sealed to prevent water ingress
- Do not overload the box; keep wire splices and connections within the internal space
- Check the seal integrity before and after installation, especially in high-moisture areas
