The terminal block is a kind of accessory product used to realize electrical connection, which is divided into the category of

connector in industry.   As the degree of industrial automation becomes higher and the requirements for industrial control

become stricter and more  precise,   the amount of wiring terminals is gradually increasing.    With the development of the

electronics industry, the scope of use of terminal blocks is increasing, and there are more and more types.

In order to ensure reliable and convenient wiring in electrical circuits, use special crimping pliers to connect the crimped

copper terminal to the wire at the end of the wire. Generally, there are OT type or UT type; for example, OT2.5-5 is a 2.5²

wire, the screw is 5mm, and the other models are analogous.

Copper Tubular Lugs Calculation of wiring

1. First, separate terminal wiring and terminal-free wiring, generally 10MM² and below are connected without terminal

(except when there are special requirements to use wire terminals, in this case, it is calculated according to the actual

situation); Soldering or crimping copper wire terminals with terminal wiring is considered.

2. Cable terminal heads of   10MM²  and  below  are not made according  to  the  requirements  of  the terminal head.

Installation, just stripping the wire head and directly crimping the connection, can not be regarded as the cable head,

only without terminal connection; such as the crimping nose, press with the terminal Calculate.

3. For all distribution boxes, cabinets, panels and junction boxes, the incoming and outgoing wires of the terminal box

are calculated according to the specifications of the wires and the number of wires. And sub-sets without terminals.

There are terminals or pressure (welding) copper terminal related quota sub-items.
