How to Choose a Waterproof Connector for Street Lighting Projects?
For street lighting projects, the minimum specification is an IP68-rated waterproof connector with PA66 flame-retardant housing, rated at 450V and 41A. Use M25 screw connectors for main supply cables (2.5–6mm²), M20 screwless connectors for luminaire branch feeds (0.5–2.5mm²), M16 screwless connectors for LED driver output (0.5–1.5mm²), and IP68 junction boxes at branching points. All components must carry CE and TÜV certification for infrastructure project compliance.
