Junction boxes provide a safe and organized connection of wires. They protect switching points from external influences, prevent short circuits and fires, and provide access for maintenance and repair of electrical wiring. A properly selected junction box guarantees the durability of the connections and meets the requirements of electrical safety.
Types of junction boxes
Junction boxes differ in the type of installation: for concealed wiring and for open installation. The manufacturing material determines the scope of application:
- plastic (PVC, polypropylene) - for most household spaces;
- metal (steel, aluminum) - for industrial facilities.
Key parameters include the degree of IP protection (from IP20 for dry rooms to IP68 for outdoor conditions), the shape (round, square, rectangular), the number and type of cable entries, as well as the internal volume, which determines the convenience of installation.
Selection recommendations
When ordering a junction box for electrical wiring, consider the following criteria:
- For indoor living spaces, you can buy inexpensive plastic products IP20-IP54 with snap-on covers.
- IP54-IP68 metal boxes with seals are optimal for industrial facilities.
- For wet rooms and outdoor installations, sealed models with oil seals are purchased.
Pay attention to the type of connection technology you plan to use (terminal blocks, sleeves, soldering) to ensure reliable contact and safety. For complex objects, it is important to combine junction boxes into groups.
Common mistakes during purchase and installation
- Incorrect choice of IP protection degree (for example, installing an IP20 box in the bathroom or outside the house).
- Insufficient depth of the product, which makes it difficult to install connections.
- Installation of plastic boxes in high temperature zones.
- Incorrect connection of the wires in the box, which leads to poor contact and risk of fire.
Placing junction boxes for electrical wiring in inaccessible places complicates subsequent repairs and diagnostics.
