For the functioning of the wiring, you need to ensure the correct wiring diagram for it, but the assembly of the circuit does not do without connecting the wires. There are many connection methods, from twisting to welding, but perhaps the most convenient and serviceable is connecting wires with terminal blocks. In this article we will talk about what they are.

The main difference in the terminal blocks is the connection method, there are two main types. Terminals with spring or lever clamp (contact). These terminal blocks can be attributed to all the famous Wago. The veins of the conductors in them are clamped using a spring or lever mechanism, and the contact, due to its elasticity, fits snugly against the clamped vein. They are very convenient to use for connecting chandeliers, sconces and other fixtures, as well as for installing electrical wiring in distribution boxes.The main difference in the terminal blocks is the connection method ...

A heat shrink tube is a material for insulating electrical connections. It is used instead of electrical tape, but paired with it provides reliable and durable insulation. The principle of operation of the heat shrink tube is to change its size when heated. It is also called shrink or shrink cambric.

Shrinkage replaced the classic cambric. Previously, pvc cambric was used for marking and insulation of wires. For marking purposes, it was actively used in automotive wiring and relay circuits, in switchboards. On it inscriptions well kept marker or felt-tip pen. When installing household wiring in junction boxes, they were also used. In this case, cambric was put on a twist, its end was heated and squeezed with pliers, after which it was glued, and the part that was on the side of the wires was wrapped with electrical tape.Shrink is available in different colors. ...

According to clause 2.1.21. PUE, connection of wires and cables should be carried out in one of the following ways: by welding, crimping, using screw or bolt connections, or by soldering in accordance with applicable instructions approved in the established manner. As you can see, the "twist" is not mentioned here at all. We can safely conclude: twisting is practically prohibited by PUE.

However, let's see why the official attitude to twisting is so unambiguous, what could be the reason for its exclusion from the list of permitted methods of connecting wires, because it is completely clear that this was done for a reason. Allowed: crimping, soldering, welding and screw connection. To begin with, we will consider what are the features of the allowed connection methods, and what is their difference from twisting. Soldering and welding require solidity and the highest possible conductivity of the created permanent connection ...

When purchasing a new induction cooker, do not rush to plug it into one of the free sockets.
