How to install a box under outlet

box for the installation of sockets - is not only a convenient way to hide the internal components of the wall, but also a mandatory safety item premises wiring.Next, let's talk about what the Escutcheon and his mount technology.


Appointment Escutcheon and types

to better understand, what is needed under the outlet box, look at the device itself outlet:

  1. inner housing, performed either ceramic or plastic.The first option is preferable, since it does not burn, but the cost of such outlets above.
  2. electrolytes.Metal plates that transmit current from the electric cable to plug the appliance plug.
  3. Circuit ground.There are many models of sockets used to connect the ground.It is expedient to do in the event that the supply voltage is unstable.
  4. plate for the clamping screws.Aluminium plate with holes for screws.Used to secure the s
  5. faceplate.Closes internal elements of the socket.


Except for the sockets are placed in the wall and the cable.Usually they are taken with a small margin, in case, if the contacts burn out and will need to replace the outlet.

The result is a lot of elements that are not protected against inclement weather.Direct hit on the condensate contacts causing their oxidation leads to a short circuit.On the other hand, fully vbetonirovat the inside of the socket in the wall can not be, since it will immediately burn the entire wiring.

Tip: sometimes used instead podrezetnikov alabaster.The material conducts electricity poorly.In 50-80 years of the last century, the load was not large, so the grid does not sboila.With the present power consumption of 6-12 kW.The use of any protective circuits except Escutcheon not allowed.


problem with fixing socket steel Enclosures.This box round or oval, made from non-flammable plastic varieties.In addition, they are equipped with a hollow core holes for mounting socket screws for easy installation and makes it more reliable.On the sides are made Escutcheon holes for cable entry.In a factory sealed plastic holes that need to squeeze or cut.

Types boxes beneath the outlet:

  • under concrete,
  • under the drywall.

Enclosures for concrete suitable for installation in any monolithic walls, whether brick, foam or any other solid material.They are fixed with putty or cement.

materials without the array, such as drywall, plywood, OSBplity, etc., do not have sufficient depth for tight fit Escutcheon.Therefore, improved crimp design legs.Using screws legs pressed against the surface of the sheet, resulting in a reliable fixation, excluding the possibility of a shift Escutcheon.


How to install a socket box in a concrete wall

To begin, consider the installation Escutcheon in a monolithic structure.Installation is carried out only after the channel shtrobleniya under electrical cable.The first thing you will need some tools:

  • punch,
  • chisel and a hammer,
  • studs 10 mm,
  • putty, construction adhesive or cement,
  • level,
  • screwdriver slot 4 mm,
  • screwdriver Cross 2mm.

Instructions shtroblenie channels Escutcheon:

  • draw power plan premises,
  • consider the placement, height and number of outlets, which are required for the room,

Tip: to reduce the load on an underwater electrical cable is carried out several lines,which are intended for specific purposes: first line - connecting household appliances with constant consumption of electricity, the second - to connect appliances with occasional use, for example, iron, vacuum cleaner, etc., and the third - the connection of lighting fixtures, including floor lamps, table lampsetc.Thus under each line requires its own Enclosures, height and number of which depends on the specific features of the room.


  • Stroebe on a cable in a place marked on the plan to drill a hole puncher,

Tip: drilling a special circular saw attachment, which makes a hole specifically for Escutcheon.If you complete this attachment was not, then drilled a few holes otdelnyh the thickest drill, and then the hole is made by using a chisel and hammer.For concrete and red brick is better to buy the same nozzle.

  • purify the resulting hole from debris,
  • podrezetnik insert, if necessary, to expand the hole.

At this stage of the preparatory work is finished.Now you need to turn off the power and proceed to the immediate installation Escutcheon.

installation boxes under the outlet includes the following items:

  • if the cable is not laid in advance, then it is connected to the counter and fixed in Stroebe to the place of the first break.The stock must be at least 10 cm,
  • in podrozetnik squeezed or cut holes for cable,
  • trimmed end of the cable insulation from the individual wires and slips into the Escutcheon,
  • podrozetnik fixed in the hole and lay cement construction glue or putty.The choice of material depends on the size of the hole, if the gap is large, more suitable glue or cement, if small - putty.

Tip: podrozetnik must be installed flush with the wall.If during shtrobleniya channel Escutcheon hole got deeper than necessary, it should be pre-fill with cement.Hollows should not be left on the side or rear of the box under the outlet.


further connected socket or switch, and after application of decorative materials set their front part.

Installation boxes for sockets in drywall

Since drywall is treated much easier to concrete, you will need to work only:

  • building knife,
  • Cross screwdriver 2 mm,
  • level.

If podrozetnik mounted in the plate based on wood chips, is added to the list of tools drill and jigsaw.Since wood as cladding material for the false wall is rarely used, in detail, this process will not be described.


Installation Escutcheon in drywall:

  • draw a plan diagram of the electrical circuit,
  • places where should be set the box under the outlet, note on a sheet of drywall,
  • attach to point a box under the socket and cut around itthe back of a pencil,
  • if you plan to install multiple Escutcheon, the level to hold the upper and lower limits to the resulting strip fasten podrozetnik and to finish the required number of holes,
  • cut construction knife channel, it should be as close as possible tailored to the diameter of the Escutcheon,
  • try a box under the outlet, if the side of the crimp screws bad pass, especially for them to penetrate the recess,
  • deduce from the cable channel and remove his isolation,
  • hold the wires in a box for mounting socket and insert it into the canal,
  • presscrimp Escutcheon screws to drywall sheet,
  • plug outlet or install a switch,
  • outer part is mounted only after all other construction work.


Useful tips

Although the process is not complicated, inexperienced builders admit many mistakes, in consequence of which outlet heated, burn, or simply fall out of the wall.Consider a typical situation:

  • sparks when switching on or off the appliance to the network.Often, due to the fact that the used or insufficient cable cross-section, or contact badly plugged.In the first embodiment, or it requires replacement of the entire line or to decrease the load outlet.In the second, enough to reconnect the socket, cut off the worn contacts.Much less the cause becomes inattention.When the mortar gets on the contacts and prevents the normal passage of current.This leads to a fine short and sparks.When installing under the outlet box is important that the contacts are clean and insulated.
  • Heating plug, socket fusion.It causes excessive load on the cable.It eliminates the replacement of the entire line.Since the cable from the meter to the first node on the technical standards set with a cross section of not less than 2.5 mm, then there are no such problems in the first outlet.But then, in order to save using a thin cable, which absolutely can not do.


  • falling through the outlet or sagging.Caused by defective installation Escutcheon.Each switching on and off of the appliance to the network creates a mechanical load on the fasteners.If not enough podrezetnik crimped or have space for it, sooner or later he will leave his seat, and socket fails.In the case of concrete, enough to lay the building empty glue and re-install the Escutcheon.The plaster is much more complicated, as the same will not be opening the box and will need to make a new one.
  • Another problem is the residual current.When you turn on or turn off the appliance happens mild electric shock or audible crackling.This indicates the presence of static electricity.It is not dangerous to health, but also the elimination of all subject.We solve the problem of connecting the ground.
  • most rarely encountered trouble - hit the wall current.By and large, this is possible only in reinforced concrete structures.Usually the voltage in the wall does not exceed 20-40 B and is not dangerous for life, but if the box is installed under the socket next to the armature voltage reaches 180 V. The cause is quite simple - when mounting the box in the pocket of her solution.It is therefore important to pay attention to in addition to wires and the inside of the outlet or switch to podrozetnik there were no other items of debris and, especially, of the solution.
