Reliable ways to connect electrical wires

Knowledge of modern technologies and methods of working with electrical accessories, is it necessary? Yes, it is necessary to know how to properly connect electrical wires.

This can be useful when installing, laying any power supply systems. Has the wiring burnt out, replacement of the lighting fixture or the completion of new equipment is needed. This knowledge may not be needed, but it will be better to know all the common ways of connecting the electrical wires

Application in the terminals of the

terminal blocks The terminal blocks are electrical products made of non-conductive material inside which is inserted a conductive sleeve that has a pair of screws from opposite ends. They serve to fix the wire. An excellent choice for the implementation of a modern method of connecting wires.

Tip: When choosing a reliable wire connection, it is important to remember: the terminal blocks are released with different holes, for many sections.

This method is almost always used for connection in junction boxes of any type, for installation, installation of wall and other fixtures. It is suitable for mounting most devices, switches and sockets. It is easy to mount the network with such accessories, just insert the bare ends into the holes and apply moderate force, reliably tighten the screws. The wire itself should not be transferred. Having disassembled how to connect electrical wires correctly with the help of terminals, it is worthwhile to study other equally reliable methods.

Evaluation of the terminal method: Excellent fastening quality. The price is acceptable. Pretty quick and easy installation. A good opportunity to connect different conductors, for example, aluminum and copper.

Sometimes the terminal blocks are sold in an inadequate quality of execution, which threatens to break them during installation. The possibility of connecting no more than two cables of the same cross section into one socket. Be sure to read how to correctly connect the wires in color.

Advice: It is not recommended to connect aluminum and multi-stranded circuits with shoe. This is due to the high brittleness of aluminum wires and the great flexibility of the conductors themselves of the stranded wire. But in general, a worthy method.

Spring terminals

Fast installation of electrical systems is sometimes necessary. For example, hold temporary lighting on the balcony, terrace, gazebo. Wago spring terminals, an excellent product for carrying out similar work. A modern and certainly a reliable way to connect the wires. Although they are recently in the market of electrical fittings, it is convenient to mount the installation with spring terminals quickly and which is important.

The main difference between the use of the terminal blocks of the wagon: they are more convenient to connect any wires in electric boxes than twisting. Here, for a quality installation, a unique clamping mechanism is used, and not a simple screw. Manufacturers produce both disposable and reusable wago systems.

• In normal performance this product is used for one-time use, during repair work it can not be restored in the future. It is removed, and a new one is put instead.
• Reusable wago terminals are slightly more expensive, but they can be used to disconnect the assembled contacts several times, remounting the circuit for your needs. This speeds up the process of repairing or mounting permanent and temporary networks. A simple lever-type mechanism gives an advantage in that it is possible to carefully and accurately fix any wire without damaging or transmitting it.

With the help of the wagon itself, the fastening is simple, it is necessary to peel the insulation and insert the necessary strands into the mounting hole. Tighten the lever. It is important to correctly calculate the load on the wires by calculator online.

Evaluation of wago clamping system: Unique possibility of combining any, aluminum, copper and other conductors. There is a variant of connecting multicore cables simultaneously( two or more).

Universal wago clamps allow, without damaging, to fix any thin stranded conductor. Another plus, compact size pads.

Excellent quality and durability. The Vago type connector has a technological hole that gives access to a screwdriver with a voltage indicator. The operation of any power line can be checked at any time. Perhaps one disadvantage is the considerable cost of the terminals themselves. But this type of wire connection is the most modern and fast.

Insulation with caps PPE

The interpretation of the product is not complicated, connecting insulating clips( PPE).They are ordinary nylon or plastic caps, which have an internal retainer.

The simplest kind of connection of wires, it is carried out after the twisting of the conductors themselves, veins. Caps are often used to connect wires in junction boxes, to mark the connections with the right color.

Evaluation of the use of such products: Quite low cost of PPE.The use of a safe material precludes ignition of the wiring. Easy installation, put on a twist of wires and everything is ready. Such caps have a large color gamut, which is convenient. Of course, if the wires are not marked in color, color PPEs have the ability to determine or simply note, zero, phase and other necessary power lines.

There are also disadvantages: Insufficient level of fixation. Stranded wire type can be mounted, only after propaque.

Installation of networks using

sleeves This option claims to be the most reliable connection method. Any of the loads and the quality of the wires.

sleeves. The conductors are inserted into a special tube - the sleeve, and crimped with a certain force. There is one thing, but. The cross-section of the wires should not exceed the cross-section of the installed sleeves. After inserting and clamping the casing, the sleeve is carefully insulated with heat-shrinkable tubing, or with the help of other insulating materials.

Overall score: Excellent way to securely connect the wires. The direction of the conductors can be from different sides of the tube or from one side. The sleeves are quite inexpensive. A good way how to securely connect the wires together.

There are also disadvantages: One-time use of cartridge cases, they are not collapsible. To produce such work, a tool will be needed: press mites, which are also used as a special tool. They remove insulation. They have a crimp device in their arsenal, and electrical work takes a little longer.

Soldering or welding wires

This method is reliable. Usually this method of connection in the junction box implies first the stripping and twisting of the ends, after they are dipped into the heated solder. The connection of aluminum wires with aluminum is preferably carried out by soldering. Then they are insulated with a thermal tube or an insulating tape.

It is strongly recommended not to immediately cool the soldered wires in water, the microcracks that occur with this kind of cooling affect the quality of the connection. They are not durable.

Evaluation of the soldering method: It gives strong circuit contacts and excellent quality, is not expensive, it is most reliable with the way of connecting the electrical wires in a torn box.

Technological flaw: Without a soldering iron here not to manage. The speed of work is not high. The connection is not naturally detachable. From this it follows that soldering is done in extreme cases, using more modern methods of connection. Among the masters, he has long been not popular, because it takes more time.

There is also not a common method of connecting electrical wires, welding. The process is similar, but requires the use of a special welding machine, of course, and certain skills.

Method of twisting contacts of

Not new, it is possible to say "grandfather's" method, it consists of spiral twisting of wires between each other. The essence of all the works is that the stripped wires are twisted with pliers, and the place of twisting is covered with insulation. Here, perhaps, and all ways of twisting wires.

Evaluation of this connection method: High speed of all installation works. The cost part is minimal.

Disadvantage: It is forbidden to join together twisted strands of different composition, copper and aluminum wires , inevitably oxidation. According to the normative base, the wires are secured with twists in the junction box, it is not recommended to use it in rooms with combustible materials, high humidity, basements, or in any house built of wood. More about the method of twisting electrical wires. Be sure to check out a video about the best twisting or terminal blocks of Vago.

Clamping device for walnut wires

This device is simply a cable clamp having two plates inside and several screws for tightening, usually at the corners. It is enough to screw the wires to the plate itself. After that, put on top the carbolite shell.

Score: An excellent option is how to connect any electrical wiring in a junction box, large and medium-sized. Certainly, these types of products are quite convenient and have a high degree of protection. It makes it possible to quickly connect the wire to the track in a thick section and not tear it apart.

Disadvantages: Dimensions allow mounting only in large junction boxes, shields. The screws loosen over time.

Tip: When choosing the fittings and the method, remember the following:

• Work is only necessary with an insulated tool, use protective equipment.
• On the trip board or counter, it is necessary to hang a warning sign, "do not switch on".
• Connect the appliance according to the attached instructions.

After considering the main types of wire connection, you will easily select the right option. And having a simple tool and a tool at hand, you can mount it yourself. In more detail how to mount the electrical panel correctly.
