Are you looking for watertight junction boxes for your electrical installations and work? Whether you need to power garden lighting, a swimming pool pump or a ventilation system in a damp grow room, safety is paramount. Culture Indoor we offer you a choice that's adapted to your installations, easy and practical to use, and above all, competitively priced.

You'll find everything you need to protect your connections from water and dust: standard junction boxes, IP55 waterproof boxes for sheltered areas, or IP65 fully waterproof boxes for direct exposure. We also supply the essential cable glands to guarantee hermeticity for cable passage, enabling you to create totally watertight branches or installations, ideal foroutdoor use.

Choosing the right protection rating: IP55 or IP65?

To guarantee the longevity of your electrical installation, it's crucial to choose the right level of protection:

  • IP55 waterproof box: These boxes protect against dust and low-pressure water jets from all directions. They are ideal for garages, cellars or sheltered outdoor areas.
  • IP65 waterproof box: This level offers superior protection. The box is totally dust-tight and protected against water jets from a hose. This is the mandatory choice for unsheltered installations in the garden or very humid greenhouses.

Cable glands and connection accessories

A watertight junction box is only really watertight if the cable entries are properly sealed. This is the role of the cable gland. This accessory is screwed onto the box and clamps the electrical cable via a rubber seal, preventing any water infiltration along the wire. On Culture Indoorour boxes are often supplied with adapted nipples or cable glands for quick installation.

FAQ - Frequently asked questions about Waterproof Boxes

What is the purpose of a watertight junction box?

It is used to centralize electrical connections (dominos, terminals, etc.) Wago) at a secure point. It can be used to divide an electrical line into several outlets (branching), while protecting bare wires from humidity, rain and accidental contact.

Can a standard junction box be buried?

No, a standard waterproof box (even IP65) is not designed to be immersed or buried directly, as water will eventually seep in under pressure. To bury connections, you need to use special boxes filled with two-component insulating gel.

How do I install a cable gland?

Simply drill the box to the required diameter (if it's not pre-drilled), screw on the gland body, pass the cable through, then tighten the compression nut (the cap) until the seal firmly grips the cable.
