First, let's review the definition of the
Terminal Block: it is an electronic component product used to connect electrical equipment.
It has many types, models, and colors. We have universal single level terminal block, multi conductor Terminal block, PE type terminal block and so on , you can see the double level terminals , it can help you save the space and cost it seems 2 pcs
Universal Terminal Block.The product line of each terminal block manufacturer has different advantages.
Then, how can the terminal block be used together?
The terminal block is used to facilitate the connection of the wire. It is actually a piece of metal sealed in insulating plastic. There are holes at both ends to insert the wire, and there are screws for fastening or loosening, such as two wires, Sometimes it needs to be connected, and sometimes it needs to be disconnected. In this case, you can connect them with terminals, and you can disconnect them at any time, without having to weld them or entangle them, which is very convenient and fast. And suitable for a large number of wire interconnections, there are special terminal blocks and terminal boxes in the power industry, all of which are terminal blocks, single-layer, double-layer, current, voltage, ordinary, breakable and so on. A certain crimping area is to ensure reliable contact and to ensure that sufficient current can pass.
In fact, the terminal is also called the terminal block.
1. What is the purpose of the
Ground Terminal block in the
Distribution Box?
The grounding terminal is a dedicated terminal for the ground wire. Now the electricity used in China is a three-phase four-wire system. The neutral and ground are separated. The ground wire is generally connected to the ground wire of the socket to protect the safety of electricity use!
2. When should the terminal block be used?
The wire connection between different devices requires a terminal block, and some plug-ins (modules) also require a terminal block.
3. When is the terminal block required in the electrical cabinet?
With a mounting unit as the boundary, a line terminal block is required to enter and exit this unit.
4. What is the role of the terminal block?
It is convenient for wiring; for example, when installing a power distribution cabinet, the signal lights or meters on the cabinet door must be equipped with terminals. It is convenient to check the line; it is convenient to measure when a fault occurs. Node expansion; node expansion with the same wire number.
