The waterproof junction box, also often called an outdoor junction box, is used to integrate the connection of external wires and protect the wires from being damaged by rain or dust. This is a box for grooming and protecting wires.
Waterproof junction boxes are generally used for power distribution, shunting, and control of outdoor circuits. Based on its different waterproof and dustproof grades, as well as different sizes of space, the internal circuit can be more flexible and changeable and can be applied to many outdoor scenes.
Such as outdoor street lights, outdoor monitoring, aquaculture, outdoor charging piles, garden spraying, and some outdoor smart circuit systems. According to the use requirements of different scenarios, the material requirements for the outside of the junction box are different. We have plastic waterproof junction boxes and cast aluminum waterproof junction boxes.
The general level of waterproofness is between IP63 and IP68, which are divided into the following categories:
Waterproof junction boxes are available in various sizes, such as 100*100*75mm, 95*65*55mm, etc. Before choosing the size of the waterproof junction box, you can first confirm the purchase requirements through the installation location and the number of wires.
The Accessories of the waterproof junction box are specially designed, processed, and manufactured to ensure the waterproofness of the product and facilitate the actual installation of the product.
The Accessories of the waterproof junction box include the following:
Compared with plastic boxes, metal boxes are heavier and more expensive, but they are more resistant to high temperatures and impact than plastic boxes. If the electrical system has grounding requirements, that is, it needs to be grounded through metal conduits and metal boxes, then the junction box can only use a metal box, because the plastic junction box cannot conduct electricity.
In practical applications, plastic junction boxes are easier to install. When the needs are met, home decoration is more inclined to use plastic junction boxes.
In the electrical code, it is required that the wiring of all electrical equipment needs to be in a qualified electrical junction box. This electrical junction box is used to organize and protect wires from the environment and also protect living beings from electrical connections.
However, there are also some other electrical equipment, which have their own internal junction boxes and do not need additional junction boxes, such as water heaters, range hoods, and other equipment.
