Simple technology of building wire and cable

There are several basic situations when you need to perform a build-up of electrical wiring.Most often, the need arises if the broken aluminum conductor in the socket, but there are cases when it is necessary to extend the cable from the appliance to connect the power.Next we will look at all of the most frequent and tell readers site itself Electricians how to increase the wire in the outlet, the water, and to connect the powerful appliances.

main methods of increasing

First, consider how you can extend the cable or the electric cable in the home.If both wires spliced ​​conductors from one metal (copper or aluminum), you can use the following ways of extension:

  1. With WAGO terminal blocks.The most convenient option is not only increasing, but also the connection of electric wires.It is recommended to use even in the situation where core conductors of different metals.Terminals wago
  2. Budget connection terminals, allowing to extend the wiring.Connection terminal
  3. Stranding.Antiquated method, which is one of the most dangerous, but at the same time, popular even experienced electricians.To increase the twist via the wiring necessary that a broken end was not less than 30 mm (for reliable splicing).To learn how to make twist the wires, see the corresponding article.Twisting Insulated
  4. Pike.Another option extension wiring - using soldering lived.If you know how to use the welding machine, the method allows to increase the quality even large conductor cross-section (4-6 mm.kv.).Pike wiring
  5. sleeves.Capacity perebitogo cable sleeve portion, actually, as the clamp nut can be used when installing electricians, but nevertheless are not appropriate method.Walnut take up much space and obviously not together in Enclosures, and crimp sleeves need to spend more time.

Please note that lengthen the aluminum core copper can only be achieved if special terminal will be used for splicing.All other options to increase line use is strictly prohibited!

So we looked at what are the methods of increasing the electrical conductors in the home.Next to your attention will be given typical cases, when you need to own to extend the wiring, and now we recommend to view a graphic video instructions:

SoNow we proceed as follows: look at each specific case, which may occur in the home, and immediately give instruction on how to properly build up a wire and cable.

  • Broke lived in the wall.If you have decided to move the outlet or switch to a different location and electrical work you broke off one of the cores, then you need to act depending on the situation vozniknuvshey.The lengths of the lead-in wire is enough to build up - install the terminal block and extend a short guide on the same cross section and material of manufacture.If in Stroebe was very short wire - break section of the wall, free long enough to build up the power cable, strip the wire to metallic colors and extend the site.This technology is also suitable in the event that you need to increase the wiring in the junction box or on the ceiling to connect lamps or any other lamps (eg, wall to wall).Lengthening the wiring in the wall
  • necessary to build the cable in water.Such a situation occurs, if desired the feed line portion extend for downhole submersible pump.In this case, experts advise to perform a portion of the conductor capacity is the same brand.Extension cable of different brands is prohibited by regulations.All you need - to make a connection through a matched residential terminals, then insulate extension location using heat shrink tubing, as shown in the photo below.It is recommended to insulate the exposed portion using a heat-shrinkable tube, even if there was a need to increase the wire in the bathroom or on the street, to protect the wiring from the high humidity.Insulation site The use of heat-shrinkable tube
  • necessary to extend the cable to power large appliances in the apartment.One of the situations to which should be taken seriously - lengthening lead-in wire to connect powerful appliances.For example, if you decide to connect your oven, air conditioning or electric stove and on entering you broke some copper conductor (its cross section must be at least 4 mm2), there's terminal block is not suitable, becausecurrent load of the appliance will be significant.In this situation, it is recommended to increase the soldering wire, then carefully insulate the tape portion.Capacity introductory wiring in the wall
  • necessary to increase the cable (or rather cable) to connect home appliances small capacity.If you have a not so brilliant idea - to perform extension cord from the washing machine, hood, microwave oven music center or to do so it is strictly prohibited.Firstly, you can by mistake during building skomutirovat properly wire and connect the introductory phase conductor with the ground, as a result can lead to dire consequences.Secondly, in this case, it makes more sense to make an extension cord with your hands and hide it along the baseboard that is safer and faster than extend a cable.Photo splicing copper wires The cable insulation shrink tube
  • lengths of wire temperature-sensitive floor heating system is not enough to connect to the thermostat.In this case, we recommend that you read the instructions attached to the product, and if no restrictions are stipulated, boldly using PVA can lead to extend the cable to the thermostat, using all the same terminal block.
  • necessary to increase the lead for LED strip lighting concealed ceiling.There were no complications in this situation should not arise.There are special connectors, which enable to perform sequential elongation LED lamp.The main thing to take into account the requirements that we have provided, when considered advice on connecting RGB tape his hands.Connectors to connect the tape segments
  • damaged twisted pair cable.In this case, perform a build-up area of ​​the new twisted pair, you can use twisted or soldering.The main thing - carefully isolate place each extension to the bare wires are not touched each other.Capacity twisted pair

That's all that I wanted to tell you how to build a wire in the socket, under water and in other unusual situations.We hope that now the extension of electric cables and wires will not cause you difficulties when installing wiring your own hands!
