Species

As you already understood, there are several types of electrical boxes today.As a rule, the separation takes place on the following characteristics:

• manufacturing material (metal or plastic);
• installation method (open or hidden);
• product shape (rectangular, round, square);
• size.

Metal and Plastic

Metal junction boxes used in the last century, when there was not invented a plastic version.

not rare metal product variant is used at the moment.In most cases the installation of junction boxes made of metal perform when installing wiring in the bath or the wooden house.This is because the metal when spontaneous combustion cable will prevent the spread of flames.

plastic version is more modern.There are products like the outer and the hidden type.Their advantage is low cost, user-friendly design and attractive appearance.By the way, there are fire-proof junction box of self-extinguishing plastic.

External and hidden

If rasklyuchenie wires in the room is carried out by open method is used outdoor junction box.When installing the product is used under the plaster hidden type.

For recessed mounting For outdoor installation

Both option does its job quite well, but still repair and maintenance of the wall of the object to perform better.

In addition, there are boxes with terminals that allow quality to connect the wires to each other.Such products are usually made in the external design.

Rectangular, square, round

junction box is also available in a variety of geometric forms.The reason for this - a different purpose.If it is fed little veins, a circular shape is enough.With a large number of wires necessary to use rectangular or even square capacity, asthey have a greater capacity.

draw your attention to the fact that the installation of the junction box of the round form in the concrete takes less time becausethere is no need to put the product on the level!At the same time to open the wiring will look beautiful square-shaped product.

regard to size, they may be different, depending on what you selected cable section.Immediately we recommend you read the article: the calculation and the cable cross-section selection for electrical work.

Instructions

connection As we said earlier, assembling the junction box can be open and hidden way.Consider the basic steps of each method.

Outdoor installation

This type of installation more simple and not time consuming.

To your attention all the step by step instructions that will help to set yourself a junction box in the wall:

2. Mark fixing points with a lead pencil.
3. Attach box in the concrete wall with dowels.Product design includes 2 holes for the screws.
4. Cut the tips of the seals for the input of all the groups of wires.Sections must have a diameter slightly smaller than the cross section of the cable to protect the wiring from dust and moisture.
5. Connect the wires to each other.To do this, be sure to check the color-coded wires.All you need to properly connect the phase to phase, zero to zero and land with the land (for the female group).To join an introductory group with a group of switches and lighting, read the article: how to connect a light switch.
6. Insulate the junction of PVC insulation, if required.
7. Close the lid.

That's the whole installation technology distribution box into the concrete with their hands.I would also like to note at once that the most reliable way of connecting wires and a soldering terminals Vago.

Flush mounting

Installing hidden way more time-consuming, but still under the power of the novice electrician.

1. You must first create a product Stroebe fit in the concrete wall.To do this, use a drill with a special nozzle crown.Pay attention to the important requirement - Stroebe diameter must fully comply with the size of the junction box.If the landing place will be little need to align the contour, if too much - more than impose a solution.
   

   Create Stroebe

2. Move the line to the place of connection of the junction box.The height of the installation - 10..20 cm from the ceiling.
3. Dissolve plaster solution and place it in Stroebe, after moistening with a little water.You can also Stroebe repaired plaster solution.
4. Put the box flush with the wall and hold a little while to get to grips solution, then with a spatula, remove the remnants of plaster.
5. Connect the wires to each other.
6. Install protective cover.
7. Cover the installation location or apply wallpaper to cover a thin layer of plaster (finish).If you could not disguise the electrical point, carefully cut out the wallpaper on the circuit (plastic cover will not stand in the bright wallpaper).

Finally I would like to give one good advice - at the time of wiring sign each group (eg, sockets, switches, chandelier, etc.).This will allow you to quickly find a vein during repair works in the apartment.

Here and all installation junction box technology with concealed wiring in concrete.This option takes a little more time, but the appearance of the room will not be spoiled.It remains only to provide you with some useful instructions and video circuits.
