Guide box is a metal box that protects electrical or telecommunications connection. The boxes have many different names such as intersections, electrical cabinets or side dishes. Within the pipes there are wires that combine local power or communication systems to the main system. These gray or green boxes are common in many low density populations; High density areas usually have underground boxes to create another layer of protection. These boxes are also common inside the factory, power plant and other industrial areas, as well as some commercial and residential buildings.
The main purpose of the box is to protect the wires inside. These boxes are usually made of robust reinforced steel, which is insulated against electric discharges from inside or outside the box. They usually have seals around the access panel that creates a waterproof interior. The doors often have an interior and an outer lock to further prevent tampering.

Using this system, the repair shop can selectively turn on and off local systems without interrupting other users.
The most likely place to run through these boxes is on the street, but that's not the only way. Many industrial machines require a huge amount of energy. Since these systems need access to greater than a normal energy system, it is not an unusual individual to end up connected similarly to the house.

commercial and residential buildings can also have internal connecting boxes. They are most common in buildings with several groups of unconnected people, such as an apartment or an office building. These pipes of boxes divide internal systems and provide each subgroup with their own approach to strength and communication. This helps in billing and provides basic protection against energy overload. The most common places for pipes in this situation are technical room or basement.
