As you make a spin-off from the wire ?

squeezing nut

When we looked at the basic ways of connecting wiresin the terminal box, particular attention was paid to the special terminal type nut.The product has a fairly simple design, but despite it allows you to tap a reliable and durable.It consists of karbolitovogo szhimnoy nut shell, a steel die and plate, which actually pushes the wires with four screws.

compact size nut, as well as the low price makes it one of the most popular couplers for the power line.In turn, product defects is low tightness (protection class IP 20), as well as the inability to tap live wires.It should also be noted that a very important advantage of "nuts" is the ability to combine high quality copper and aluminum wires with section from 1.5 to 150 mm2.

All you need - to lay bare the contacts in a special plate and carefully tighten the screws with a screwdriver, and then snap the body.

Piercing Clips

upgraded model of cable compressing the nut are piercing clamps.Disposable articles, however, do allow the branch wire without cutting, and even without scraping the insulating layer by bonding.Clip design presented hexagon, which pulls together strands, as well as contact plates with teeth, which actually pierce the insulation material.

The advantage of these products is as follows:

• be branched wires from the overhead line (VL) can even live without fearing for their safety.This is due to the fact that the contact plate isolated reliably from the clamping bolts;
• body products sealed and protects the connection from the bad weather;
• clips easy to use and have a long life;
• low cost of production;
• opportunity to bond copper and aluminum conductors.

As for the drawbacks, the main thing is just a "one-off" products, but this time is very controversial, given the longevity of this method of branch wires without breaking.

Installation is as follows:

clamp type OB

When repairing or replacing the electrical wiring in the apartment it is fashionable to use another pretty good option splice - using type clampsRH.The products have a simple structure and at least a simple principle - the cable is laid in a special latch that brass connector pierces the layer of insulation.As a result, in a matter of seconds you can make a good branch from the mains cable, the main thoroughfare (for example, at the outlet).

Regarding the shortcomings of latches, the main application is limited to conditions - a cross-section of cables must not exceed 6 mm2.In turn for home wiring this section should be sufficient even to connect a powerful electric cooker.

Terminal block ABAC

more outdated way of branch wire - use terminalDCS pad.Compact terminal blocks are not recommended, becausein this case, without cutting the main conductor and the gap is not enough.In addition, the terminal block has more disadvantages such as poor sealing and the need to periodically tighten the clamping screw, especially if aluminum conductor.As a result, you do not get any significant advantages splice and at the same time get some serious shortcomings.

antiquated twist

Well, the last branch wiring method, which can be used - a new twist to the line passing backbone without additional soldering or welding.In this case, you must first clean up the insulation, and then branch off the line well screwed on the backbone (as shown in the picture).

Please note that when creating a twisted prohibited from joining aluminum and copper conductors.Conductors must be made of a metal.Rules of the SAE to use such a method is not recommended because of its unreliability.To learn how to make twist the wires, see the provided article!

Here, actually, we have provided the most popular ways to tap the wires without breaking and cutting.Now you know what you can do high-quality splicing two electrical lines.Our advice - use the piercing clips that among all the options cause the greatest trust!
