surface mount distribution box with mounting plate Introduction:
Made of strength ABS and PC material, the enclosure has beautiful appearance, high plasticity and doggedness. LWHA series distribution box is suitable for terminal boxes, distributionpanels nstrument boxes. electrical equipment boxes and control boxes. Moreover, it is simple and easy to use.
(1) surface mount distribution box with mounting plate Fixed panel switch cabinet, often called switch board or distribution panel. It is a kind of open switch cabinet with panel block, the front has protective effect, the back and the side can still touch the live part, the protection level is low, can only be used for industrial and mining enterprises with low requirements on the continuity and reliability of power supply, for centralized power supply of substation.
(2) Protective (i.e. closed) switchgear refers to a low-voltage switchgear with all sides closed except the installation surface. The electrical components of the cabinet, such as switches, protection and monitoring control, are installed in a closed housing made of steel or insulation, reliably wall or wall mounted. No isolation measures can be taken between each circuit in the cabinet, or a grounded metal plate or insulation board can be used for isolation. Usually the door is mechanically interlocked with the main switch operation. In addition, there are protective platform type switchgear (console), the panel is equipped with control, measurement, signal and other electrical appliances. Protective switch cabinet is mainly used as power distribution device in process site.
1. Wiring diagram of household distribution box:
1, first of all, home distribution box wiring, to see the wiring diagram of home distribution box design, do not confuse the live line and zero line, if the two lines once connected wrong, there will be no power supply, easy to cause a misunderstanding. Whether connected or opposite, will let the neutral line and live line action, because many of the zero line in the leakage switch is together with the inside, so after opening the gate, disconnect only live line. The way to distinguish the neutral line and the live line is very simple, you can look at the leakage switch, which is usually marked, if it is the letter N for the zero line.
2. The application range of household distribution box is different, and the wiring method is different. Household household distribution box wiring diagram is relatively simple, generally people who have learned physics can understand, if it is building and other places of household distribution box wiring diagram, then it is more professional, ordinary people can not understand. If the installation of household distribution box, need to buy into the line, choose 4 square meters can be, through the leakage switch in the live line connected to the household distribution box total switch, and then through the live line connected to the switch in each room, because the zero line is public, only need to separate to each room.
Before 3 distribution box, installation of household, will be involved in the equipment is ready to complete, and then measure the household rated current of the circuit and the working voltage is how much, again according to the household circuit of power supply into line configuration a similar domestic distribution box, and then design a household distribution box wiring diagram, through the domestic distribution box installation wiring diagram into line, according to the process to step by step, You'll get twice the result with half the effort. About the installation of circuit equipment, or need to find the electrician cook amen to install, after all, electricity is a very dangerous thing, can not be touched casually.
