External retro wiring - design techniques and features

First of all, you should correct the misconception that retro wiring is performed exclusively with an open cable. Laying in electrical pipes made of painted metal and copper-like plastic is allowed. Such pipes, in addition to decorative, also perform a protective function. In addition, they make it possible to use a regular cable. This method of external laying is used in scandinavian style (wood interior decoration) or loft (brick and concrete walls). Also, according to the requirements of the PUE, cable laying in pipes is carried out in rooms with high humidity: bathrooms, showers, saunas, etc.

Antique open cable laying is typical for interior Provence styles, country and shabby chic. In addition, some elements of vintage wiring, such as sockets, switches and external junction boxes, are also used for concealed installation in Art Nouveau and Victorian styles.

Advantages and Disadvantages of Retro Wiring

Before deciding on the use of external retro wiring, you should find out about its advantages and disadvantages:

  • operational installation. As practice shows, it will take 2-3 days for the owner of a two-room apartment to lay wires in an open way and install sockets and switches without any experience. The master will cope with such a task in 6-8 hours.
  • Dusty and time-consuming processes of wall chipping and drilling of sockets for electrical fittings are excluded. In addition, in some panel houses, damaging the walls with strobes is strictly prohibited.
  • availability. Open-cut cables are always available for repair, replacement or modernization.
Important! It is better to entrust the connection to the switchboard and the wiring to professionals!

Of the negative aspects of retro wiring, the user should be aware of the following:

  • high price... Despite the exclusion of such costly and time-consuming works as wall chasing followed by closing the chase, retro wiring can be an order of magnitude more expensive than the usual, hidden method. The main factor behind the high cost is expensive electrical fittings and cables;
  • technical features... In rooms with high humidity, vintage wiring should always be done in hermetically sealed metal pipes. Switches and sockets must have additional protection of at least IP 68;
  • design restrictions... Vintage electrical wiring looks harmonious in a limited list of not very popular interior styles. The most common of them are: country, loft, Provence. Techno, steampunk, classical are considered less popular.

Retro wiring, especially in a wooden house, requires a more thorough approach to fire and electrical safety. When buying cables and accessories, you need to pay attention not only to design and external data, but also to quality, manufacturability and reliability of performance. It is most advisable to purchase products from branded manufacturers. Leading products of Italian companies:

Russian manufacturers are much less represented. Worthy companies include Lindaswhose products are not inferior in quality to elements of retro wiring Bironi... Chinese goods are widely represented, but the quality of their products leaves much to be desired. The most worthy (albeit mediocre) reviews were awarded to products Salvador.

Twisted retro wire

The cable for retro wiring is produced in the form of stranded copper wires with a cross section of 1.5 and 2.5 mm². Other types of sections are very rare. The wires are polymer-insulated from the following materials:

  • Pvc - elastic, but with low strength, it is used only stationary;
  • elastomer - during operation it can stretch, therefore it requires more frequent fastenings;
  • polyurethane - durable, has mediocre elasticity, requires bending along a large radius.

The outer decorative insulation (braid) is made of technical cotton or silk. Brand manufacturers impregnate the braid with fire retardant compounds or fill it with varnish.A wide range of colors and patterns on the surface of the wiring are very diverse, which allows you to choose the right option for any design solution.

Retro sockets and switches for open wiring

Sockets - overhead, often have special installation frames (1-3 places) made of wood, plastic "metal" or ceramics. For devices that are often used, it is best to use ceramic, as they prevent heat.

"Some landing frames have a radially curved base and are designed for retro wiring in a wooden (log) house, although the price of such products is significantly higher than usual."

The switches have several options for mechanisms:

  • tumbler - more reliable and more familiar to use;
  • turning - there are one, two and three-contact, thanks to which it can switch several circuits.
Typically, sockets, switches and junction boxes are selected from the same collection

Holders, passages and rollers (insulators) for retro wiring

Outdoor retro wiring in a wooden house is fixed to the walls with special insulators. They look like small relief cylinders with a base diameter of 18-22 mm and a height of 18-24 mm. The upper part - the "head" can be narrow for mounting a two-core cable and wide for a three-core cable. Manufacturing material - plastic or porcelain. Wall mounting is carried out through a hole in the center with regular or decorative screws.

Rollers are produced in different colors, often complete with other elements of electrical accessories

Passages refer to decorative and protective electrical elements. They represent a decorative sleeve with a collar covering the hole through which the cable is led out of the wall. Manufacturing material - porcelain.

Vintage cartridges are made from brass, aluminum alloys, copper, carbolite or metal-painted polymer materials. As a rule, their design provides for a switch, as well as technological holes, threads and washers for fastening lampshades etc.

Lighting fixtures in vintage style

Professional designers, when developing a retro interior, as a rule, create original lighting fixtures. You can try to create them yourself, combining vintage sockets and decorative light bulbs with unusual shapes with a base. An electric cable fixed on several rollers is used as suspensions. It is much easier, but more expensive, to purchase ready-made lighting fixtures "for retro" like ceiling lamps and chandeliers, and wall sconces.

DIY installation of open wiring in retro style

First of all, as in conventional electrical work, a plan is created for laying cables and the location of the main elements of electrical fittings.To do this, you need to have a large-scale apartment plan or a floor plan of a private house.

Calculation of the amount of retro cable for outdoor wiring

As a rule, the amount of cable is determined by the diagram. 10-15% is added to the received footage. However, the price per meter of retro wiring is very high, so it is more advisable to take measurements with a tape measure directly at the facility. To the resulting footage, add 10 cm to connect each switch and socket, 5 cm for the junction box and at least 15 cm for each lighting fixture.

An expert's point of view
Alexey Strakhov

“To save on expensive retro cable, part of the wiring can be done with ordinary VVGng wire, laying it hidden under a layer of plaster. The visible part of the wires is led from the junction box directly to the connection points. "

Installation of retro wiring in a wooden house

DIY installation of retro wiring is carried out in the reverse order from peripheral devices to the junction boxes and further to the terminal blocks of the shield. There are special recommendations for laying outdoor wiring lines:

  • the first roller (insulator) should be fixed no further than 5 cm from the outlet (switch, junction box);
  • if the wire is not allowed to bend at right angles, 2 insulators and an angle of 45º can be used;
  • if two pieces of cable need to be connected in the middle of the wall, a junction box is used;
  • when using a three-core cable, it is necessary to strictly observe the order of fastening to the insulator. Two veins on one side, one on the other;
  • the horizontal step of installing insulators is no more than 40 cm.
Important! Considering the maximum cross-section of the vintage cable of 2.5 mm², it is strictly forbidden to connect powerful electrical appliances such as an oven or hob to it.
