The round aluminum junction box is another geometric shape of electrical junction box that is abundantly used in various structures. In terms of installing and connecting terminals inside this aluminum junction box, there are no limitations. Therefore, you can determine the number of connections and the number of terminals based on the size of these boxes. A metal cover is placed on the round aluminum junction box, which is responsible for protecting the inner compartment of the box as well as protecting its internal connections.
To prevent these covers from easily detaching from the box surface, they are usually attached to the main body of the junction box using two screws. Their manufacturing material is aluminum alloys. The type of metal used in the manufacture of the round aluminum junction box has a very high density, so it can resist environmental stresses such as impact and pressure. As much as possible, they do not suffer structural breakage due to the application of force. For this reason, you can install them with confidence in high-stress spaces and at the heights of a structure. In the continuation of the article, we will discuss this type of specific junction box in detail so that you become fully familiar with them.
To create branches in wires and cables safely and achieve the best performance in electrical installations, it is necessary to use various equipment. One of these pieces of equipment is the junction box. The round aluminum junction box is designed in such a way that, in addition to creating electrical branches, it can protect various cables and branches and also conceal the cables from view. This matter, while providing support for the electrical cables, can also minimize the risk of cable tearing and create greater aesthetics in electrical installations when creating branches, because a large portion of the cables is hidden from view.
This type of junction box, due to being covered, increases the possibility of convenient access to various branches for repair technicians. Repair technicians and electricians can have simple access to the branches inside these junction boxes. The terminals used in these junction boxes can give them better organization and, at the same time, create more beauty and order inside the junction boxes. Therefore, this type of junction box, with its superior features, is usable not only for electrical installations but also for electrical repair technicians and can hold a special place.
This product, due to its round, circular structure and having 4 outlets, has very numerous applications. The specifications and features of this product that buyers should pay attention to before obtaining it include the following.
High resistance to rust: This junction box is manufactured with a rust-resistant coating and has high resistance to corrosion and rust. Therefore, they can be used in humid environments or those with high moisture sensitivity.
Resistance to moisture: The round aluminum junction box has high resistance to moisture. Besides being rustproof itself, it can effectively protect the cables and wires placed inside it against moisture and demonstrate a resistant structure. Therefore, installing these junction boxes also leads to increased durability of the cables inside them.
Absence of threads: Round aluminum junction boxes either have no threads, or their threads are very narrow. Therefore, they can be connected to electrical steel conduits and other conduits with the help of brass bushings.
Sheet thickness: The sheet thickness of the round aluminum junction box can be changed and customized according to the customer’s request. However, these products can be ordered with a thickness of 0.7 millimeters and 0.9 millimeters, each having acceptable performance.
Cover: To achieve the best features and prevent dust from entering the junction box, a thin aluminum or galvanized cover is placed on these junction boxes, which increases their strength.
Support for steel conduits: Due to the variety of sizes, the round aluminum junction box can support a wide range of steel conduits. Therefore, by considering the punch size of the body and its cavities, customers can obtain the best type of these junction boxes.
Many customers, when purchasing the round aluminum junction box and other available types such as the 10×10 aluminum junction box, the 15×15 aluminum junction box, and larger sizes, raise the question: can these junction boxes be used exposed to environmental weather and in humid spaces, or not? In response to this question, we must say that it is possible. The reason for this is the presence of a protective coating known as electrostatic powder paint on these parts.
Of course, there are also other types, such as the galvanized junction box, which are mainly used in industrial environments such as sheds and workshops, that have a different protective coating. This is the hot-dip galvanized coating, where the metal parts are immersed in a molten zinc bath. Electrostatic powder paint is at a high level in terms of resistance degree. Although parts with a hot-dip galvanized coating have relatively greater resistance, the various types of round aluminum junction boxes coated with electrostatic powder paints have also been able to maintain their structure without rusting in open, humid environments.
As mentioned at the beginning of the article, there is a metal cover on the round aluminum junction box, which is attached to the main body by two screws. The connection type of these covers is such that it can create a very fundamental seal on the surface of the junction box enclosure. Of course, some types of round aluminum junction boxes as well as square types and other geometric shapes have a rubber sealing strip placed on the cover of these parts. Therefore, when you attach these covers to the junction box body using the two mentioned screws, not only are fluids unable to penetrate into the junction box, but other damaging environmental elements such as dust also cannot enter the junction box enclosure.
This valuable feature is not only present in the cover part of these parts, because you can also see their sealing in the cavity part, precisely the area where the conduits and cables enter the junction box. The glands used on the conduits and cables when entering the junction box can create a completely sealed and watertight connection in the cavity part present in the junction box body. In fact, this is precisely one of the main functions of glands.
Terminals or connection terminals are relatively small parts usually used inside various types of junction boxes. These terminals are responsible for creating safe connections inside the junction box. When cables enter various junction boxes such as the galvanized junction box and other types, in order to create safe and correct branching, they are placed inside rows of terminals.
The terminal structure is such that it can be made of polymer material or in ceramic form. Of course, this type of material is present on the external part of the terminal, because its center, for creating the branch, is made of metal. Connection terminals, in addition to creating electrical connections inside the boxes, also act as an electrical insulator. Any connection made in any terminal must not come into contact with the next terminal beside it. Preventing this type of contact, as mentioned, will also be achieved due to the presence of a plastic or ceramic wall.
Therefore, if for any reason you intend to create cable connections and branching inside the junction box, you must definitely use the correct rows of terminals, because without this very important element, you cannot connect the cables to each other scattered inside the junction box and without electrical insulation, as this will certainly cause damage to the cables as well as to your complex. It makes no difference whether you use a round aluminum junction box or square types and other geometric shapes. In all these parts, the presence of terminals is among the essentials for creating a safe cabling network.
