HOW TO MAKE AN ELECTRICAL SYSTEM ON PLASTERBOARD WALL
How to outline the system.
1. Inside the metal structure that composes the plasterboard wall, at the rear of the slab, trace, with a construction pencil, the lines that will indicate the passage of the corrugated pipes. (N.B: in the case of adhering false walls, the traces must be made on the wall with a special marker).
2. On the lines just drawn, place the tube-blocking rings that will serve, together with the clamps, to fix the "corrugated" by mapping the project.
3. During the mapping phase it will also be established where the holes will be made on the slab for the subsequent assembly of the electrical boxes (drill with a circular hole saw diameter 63) and for the assembly of the junction boxes (drill with a hacksaw for plasterboard).
Fixing of corrugated pipes
1. Pass the corrugated pipes through the previously positioned pipe clamp rings and secure everything with the clamps.
2. Near the exit points established on the project for the positioning of the electrical boxes, cut the pipes with scissors. This operation will subsequently facilitate the assembly of the system. (N.B: it is suggested to abound with the length of cables and pipes so as to avoid having to lay everything down again or create dangerous joints during processing).
Creation of exit points
1. First of all we will proceed with the fixing of the plasterboard sheets, with some 3.5x25 black phosphated self-tapping screws, nail tip, on the aluminum structure to close the created wall (or counter wall).
2. Using the map-project previously drawn, the access points for the insertion of the electrical boxes will be identified by indicating them with a pencil on the plate.
3. On the points just marked, mill the slab with a hole cutter with a diameter of 63 or, in the case of junction boxes, with a simple hacksaw for plasterboard.
4. Now take the previously cut pipes in abundance from the inside of the wall to the outside.
5. At the end of this operation we should have about 10/15 cm of corrugated pipes protruding from the wall.
Assembly of electrical boxes
1. Pass the pipes coming out of the wall, inside the electrical box.
2. Now insert the electrical box in the recess created on the wall and if the cable length is correct, there should be about 10/12 cm of protruding cables to be able to work comfortably and at the same time avoid waste by making patches or last minute additions .
3. Screw the steel fins on the electrical box with a screwdriver with depth adjustment, making sure that they are fixed to the plasterboard sheet. N.B: not all electrical boxes on the market have screwable steel fins and therefore it is advisable to pay attention during the purchase phase.
Finishing the electrical boxes
During the phase described above, it may be necessary to reinforce the points around the well with polyurethane foam before inserting the electrical box. This operation mainly has two functions: the first is to improve the tightness of the steel stains of the boxes on the slab and the second is to strengthen the stiffness and mechanical strength of the plasterboard in an area that could be critical due to the hole created for the entrance electrical supports.
Passing of electric wires
1. Once the previous point has been completed with the creation of the holes and the subsequent assembly of the electrical boxes, the work is essentially finished.
2. Having created a new electrical system, it will be necessary to pass the electrical cables inside the corrugated pipes and then proceed with the wiring by connecting the appliances to the conductors by cutting the electrical cables to the correct length (NB: do not leave wires protruding outside the closing terminals).
3. It will also be important to evaluate the insertion of a new control unit that can house a multiple circuit breaker and that has multiple exit points, compatible with the needs of the new system.
Completion of the work
1. We will now proceed with the finishing touches by installing sockets and switches in the boxes, checking their stability.
2. Fill and repair any parts of the plate that may be damaged during the box fixing operations.
3. Complete the work by evenly painting the wall.
Tips Tuttocartongesso:
Working on the electrical system is complex and articulated both because it is made up of several elements and because it is "potentially" dangerous work.
In the face of this, the rules governing its creation and installation are rigid and safety-conscious.
We therefore recommend that you do not do it yourself for this type of intervention.
The installation must be done only by companies registered with the the Chamber of Commerce who will then issue the "Declaration of conformity of the work performed" which will certify that the circuit is in compliance.
To regulate the construction of electrical systems are the rules:
• CEI 64-8 (Italian Electrotechnical Committee) - entered into force on 1st March 1993 - and variant V3 of the standard itself, which came into force in September 2011.
• Decree of the Ministry of Economic Development n. 37 of 22 January 2008 (published in the Official Gazette no. 61 of 12-3-2008), which replaced law 46/1990.
In the event that you wish to proceed with the private construction of the system, the following are some basic tips:
1. Use standard materials:
2. pipes and cables of a certain thickness based on the electric current passing through them.
3. approved and above all insulating and fireproof sockets and switches.
4. Before performing any type of work, disconnect the house power supply.
5. After completing the installation work on the system, before completing the closure of the plasterboard wall, it is recommended to have everything checked by a plant engineering expert and / or qualified personnel.
