Replacement of electrical communications

Both his hands to replace electrical equipment in the apartment

The condition of the wiring in the apartment or private house is crucial for comfort and safety. It depends on stable operation of electrical appliances and home appliances. Most fires happen because of problems with wiring, so timely replacement of electric utilities in the apartment with his hands is a responsible and necessary.

What you want to change the wiring

The need for a harness replacement is called for the following reasons:

• Parameter mismatch of the cable is small cross-section or insufficient number of wires.
• The poor condition of the transaction that were installed in Soviet times.
• The replacement of aluminum wires to copper.

For older apartments or houses is the most common reason is the dilapidated state of the transaction. In new houses it is often necessary to increase the power or change the material of the cables. In addition, modern electrical and household appliances require grounding electrode.

Methods of laying electrical communication

There are two basic methods of strip:

• In a prepared chase (groove in the walls or ceilings, where fit wire).
• Mounting on the ceiling or on the floor without breaking the surface of the walls (under the false ceiling or flooring).

Installation in the chase is the classic method, but it is not always desirable or possible. Modern methods of laying electrical communication allow to do without the extra time consuming and dusty work, making the installation under suspended ceilings, floor coverings, special channels, and moldings, etc.

This requires to use a special cable with double insulation or placed in a corrugated metal pipe. In the old panel houses the cable is laid in special channels laid in concrete slabs. You can try to stretch reason in them, using a rigid steel wire. It is passed through the channel and then tie to the end of the cord and stretch it through the channel.

Preparatory work

Before the direct work necessary to prepare:

To calculate power and loads.
• To make a diagram of the wiring arrangement.
• Clean all bearing surfaces of the facing or skin materials, to remove the hinged furniture, remove false ceilings or flooring.

Neglected preparatory procedures should not be.

Special attention should be paid to calculations and charting, which should be marked the location of outlets, boxes, panels and other components of the system power supply. It is important to comply with all requirements of the building regulations governing the number and location of sockets, switches and boxes.

Tools and materials

To replace the wiring you need:

• Cable.
• Connecting pads (terminals).
• Flaps with instruments off (machine guns, main breaker).
• Sockets, switches.
• A ruler, tape measure.
• Hammer drill, angle grinder with a diamond wheel.
• Pliers, screwdriver, tool for removing insulation.

May require other tools or materials. It depends on the complexity of the power supply system of the house, the capabilities of the owner and other factors.

Step by step instructions harness replacement

Consider the process of replacing the harness:

Step 1. Label the walls or ceilings according to a predetermined scheme.

Step 2. Full blackout of spaces. Remove old the old wiring (if necessary). The penetration grooves (if adopted hidden option wiring).

Step 3. Making holes for sockets and boxes.

Step 4. Laying of wires. Installation of switches, sockets, flaps.

Step 5. Connection machines.

Step 6. Trial supply of electricity and measurements.

Upon detection of any errors the system again, disconnect and eliminate all the problems. Final commissioning is possible only when you are completely ready to the transaction, without defects or defective areas.

It must be remembered that any problem can cause failure of electrical appliances, electric shock, human or animal, the source of the fire. To eliminate these dangers should at all production stages, from design, to the installation wiring.
