FAQ

Quick answers about selecting and using a waterproof distribution box. If your question isn’t covered, contact us for help.

What IP rating do I need—does IP65 cover outdoor rain?

For general outdoor exposure, an IP65 waterproof distribution box is suitable for rain and dust. Projects with heavy spray or temporary immersion may specify IP66–IP68. Always confirm local codes and test conditions before installation.

AT vs HT—how should I choose?

AT focuses on compact, value-driven builds for straightforward cabling. HT offers more internal room for cleaner routing, extra terminals, or DIN-rail modules. If unsure, share your circuit count and cable entry plan via Contact Us.

ABS or polycarbonate—what’s better for a plastic enclosure?

ABS provides good strength–to-weight at lower cost; polycarbonate improves impact and temperature resistance. Both can be UV-stabilized. We can recommend a plastic waterproof distribution box material based on your site (sun exposure, temperature, vibration).

Can I mount DIN-rail devices inside?

Yes. Selected sizes accept short rail sections for breakers, relays, or terminals—effectively making a DIN rail waterproof electrical distribution box. Verify clearances and heat dissipation.

What accessories should I pair with the enclosure?

Use PG/M glands with strain relief, vent plugs to reduce condensation, and labeled terminals for serviceability. For protection and isolation, see DC FUSE, DC SPD, and DC SWITCH DISCONNECTOR.

How do I size the box (ways / circuits / rows)?

Count present circuits plus 20–30% spare. Check device height and bending radius for your largest cable. If the DIN rail is required, confirm row spacing and label area before finalizing the model.

Do you support customization or pre-wired assemblies?

Yes—drilled entries, special gaskets, labeling, and pre-wired kits are available through our DC Distribution Box Manufacturer service. Share your BOM and we’ll propose a build.
