Matters needing attention when installing the distrinution box
Many people do not know what to pay attention to when installing the distrinution box, mainly the following.
Taboo 1: The lighting distrinution box enters the site without inspection.
Consequences: The lighting distrinution box is not inspected when entering the site. It is often found after installation: its second-layer board does not have special grounding bolts, the cross-section of the protective ground wire is small, and the openable door equipped with electrical appliances does not use bare copper cords Reliable connection with metal frame, weak connection between wire and appliance, reverse loop phenomenon, screw nut does not need galvanized parts, wire diameter does not meet the requirements, not marked by color code, no card cabinet and electrical circuit diagram, appliance layout, spacing It is unreasonable, no N and PE terminal blocks are set, and the delayed construction period will also affect the quality.
Taboo 2: Use wooden materials that have not been flame-retardant for lighting distrinution box.
Consequences: If the lighting distrinution box is used in a humid and dusty place, it is easy to mold and leak; in addition, if the wooden box (board) is not flame-retardant, it is easy to cause fire and is an unsafe hazard.
Taboo 3: The lighting distrinution box is not installed firmly, and the elevation does not meet the requirements. When concealed, the edges of the panel are not close to the wall.
Consequences: The installation elevation of the lighting distrinution box does not meet the requirements, the installation is not firm, the box body is not vertical, when the panel is concealed, the surrounding edges of the panel are not close to the wall, which affects the use function, and the look and feel is not good.
Taboo 4: The lines in the lighting distrinution box are crossed and messy, and are not tied into a bunch.
Consequences: The wiring in the lighting distribution box (board) is messy, and the two-layer board in the box tightly presses the nozzle, which affects the wire entering the box. If it is reluctantly squeezed in, the wire insulation will be damaged for a long time, which may easily cause a short circuit. And make maintenance inconvenient and affect perception.
Taboo 5: Do not install N and PE busbars in the lighting distrinution box.
Consequences: N and PE busbars are not installed in the lighting distrinution box, and the safe operation of the line cannot be guaranteed.
Taboo 6: The wiring of the spiral fuse installed in the lighting distrinution box is incorrect.
Consequences: The screw fuse installed in the lighting distrinution box is incorrectly wired. Connect the power cord to the screw terminal, which affects the replacement of the fuse, and improper operation may also easily cause electric shock.
Taboo 7: The protection line of the lighting distribution box (board) is not in place, and the wire diameter does not meet.
Consequences: The protective wires of the lighting distrinution box are not arranged from the terminals, but are connected in series by the box structure. The wire diameter is not set as required. The devices with ultra-safe voltage on the door of the distribution box are not equipped with protective ground wires. It is easy to cause safety accidents.
