Waterproof Junction Box 48mm x 26mm x 20mm

This surface-mounted plastic enclosure seals wiring connections against moisture and corrosion. It suits DIY electrical projects that need a compact, weather-resistant housing for switches or splices. The black finish blends into automotive, marine or outdoor installations. Buyers who need a larger internal volume or multiple cable entries should choose a bigger enclosure.

Thermals Noise and Power Draw

The sealed plastic body adds no active cooling and draws no power itself. It simply shields the connections inside from water ingress and environmental contaminants. No fan noise or heat is generated by the box. Installers who require active thermal management for high-current components must add their own ventilation or heat-sinking solution.

Upgrade From Open Terminals

This box replaces exposed terminal strips or taped splices that degrade in damp conditions. The upgrade is worth it when wiring runs through engine bays, bilges or exterior lighting circuits where splashing occurs. The 6 mm entry holes accept small-gauge cables; projects needing thicker conductors or conduit fittings will require a different enclosure.

Questions about this item

How do I surface-mount the 48mm x 26mm junction box and what step is often missed?

Drill 6mm mounting holes matching the box footprint, fix it with screws, then seal the cable entries; the step often missed is applying sealant around each gland to keep the IP rating intact.

What part will need replacement after long outdoor exposure?

The plastic enclosure and its sealing gasket can become brittle from UV and temperature cycles; inspect the gasket yearly and swap the box if cracks appear.

What thermal limit appears first when the box runs continuously in direct sun?

The sealed plastic body reaches its softening point before internal components overheat, so the enclosure itself is the first thermal limit under sustained solar load.
