Safety of placing a floor panel on an adjacent wall

It is perhaps impossible to imagine a new building today without ShchE floor panels. They are responsible for receiving and distributing electricity with a voltage of 220V. They also prevent current leakage to the ground (in the presence of a grounding system). In addition, floor boards protect apartment lines from overloads and short circuits. The floor shield ShchE is necessary for:

• implementation of distribution and metering of electrical energy of three-phase alternating current with a frequency of 50 Hz. And voltage 220/380 V. in networks with solidly grounded neutral
• to protect outgoing lines during overloads and short circuits
• for necessary operational switching on and off
• for installation of low-current equipment.

About floor panels

Structurally, the shield is a welded metal structure with a partition that forms three compartments:

• subscriber;
• distribution;
• low current

Each compartment has a door, and inspection windows are provided on the front side.

There are three types of shields:

• distribution - for connecting apartment registration and group panels;
• accounting and distribution – for connecting apartment group panels and apartment electricity metering;
• accounting-distribution-group – for connecting group circuits of apartments and apartment-by-apartment electricity metering.

Shields are classified according to the following criteria:

1. Design related to the type of installation

1.1. Wall mounted.

1.2. Built into a niche.

2. The presence of a low-current compartment

2.1. With compartment.

2.2. No compartment.

3. Method of protection against electric shock according to GOST 12.2.007.0-75

3.1. Class I.

3.2. Class II.

4. The presence of a device at the input panel

4.1. With the device.

4.2. Without a device.

5. Number of input phases into the panel

5.1. Single-phase with estimated power at the apartment input <=11 kW.

5.2. Three-phase with a calculated power at the apartment input >11 kW.

6. Number of phases of distribution circuits

6.1. Single-phase.

6.2. Three-phase.

7. Number of phases of group circuits

7.1. Single-phase with estimated power at the apartment input <=11 kW;

7.2. Three-phase with a calculated power at the apartment input >11 kW.

8. Availability of a device for protecting and disconnecting the supply circuit (riser)

8.1. With the device (or a designated place for its subsequent installation by the consumer);

8.2. Without a device.

9. Availability of instruments and devices for remote data acquisition and/or remote control and/or remote (automatic) control of power consumption mode

9.1. With instruments;

9.2. No instruments.

At the first stage, when installing floor panels and creating an installation diagram, it is necessary to adhere to the plan for the location of the circuit elements. This will help make the device compact and less expensive.

Create a schema

It is best to entrust it to an electrical engineer or a specialized organization

The unit of measurement is one module. The module is equal to the area occupied by a single-pole circuit breaker. The width of one module is 17.5 millimeters. This standard is international.

Pipelines

It is not recommended to lay pipelines (plumbing, heating) through electrical rooms.

Pipelines (plumbing, heating), ventilation and other ducts laid through electrical switchboard rooms should not have branches within the room (with the exception of a branch to the heating device of the switchboard room itself), as well as hatches, valves, flanges, valves, etc.

Laying gas and pipelines with flammable liquids, sewerage and internal drains through these premises is not permitted.

Doors to electrical rooms must open outward.

7.1.30. The rooms in which the ASU (input switchgear) and main switchboard (Group distribution board) are installed must have natural ventilation and electric lighting. The room temperature should not be lower than +5°C. 7.1.31. Electrical circuits within the VU (Input device), ASU (Input distribution device), Main switchboard (Group distribution board) of distribution points, group panels (apartment panels) should be made with wires with copper conductors.

That's all about installing an apartment electrical panel according to the rules! Good luck to you in your endeavors!

6. Hacksaw for metal
7. Hammer
8. Screwdriver with different attachments

Installation of floor board

The installation of the electrical panel should be carried out by a specialized electrical installation organization. In some cases, it is possible to carry out work using an economic method, but at the same time it is necessary to allocate additional human and material resources.

Stages of installation of floor panels:

1. Mounting the housing on a wall or in a prepared niche
2. Installing Electrical Wiring into the Housing
3. Wiring stripping
4. Installation of mounting rail (DIN rail)
5. Fastening all components to the tire
6. Installation of ground and zero buses
7. Cutting wires for jumpers
8. Connection of installed equipment according to the diagram
9. Inspection of the shield and visual quality control of connections
10. Sealing and connecting the electricity meter in the presence of a regulatory organization
11. Test run.

Anti-vandal cabinet KMA

Most often, expensive equipment is installed in floor panels. Therefore, there is often a need to protect it. A simple floor panel will not be able to cope with such a task, since the lock that protects against unauthorized access is too weak. To ensure maximum protection, you will need to use a vandal-proof cabinet. They can also be installed outdoors or indoors. The door in such devices can be retractable or hinged. Special brackets should be used to secure wiring or telephone wires.

KMA floor anti-vandal shields are made of metal with a thickness of at least 0.8 mm. Subsequently, the body is painted with powder paint, which is resistant to corrosion and external influences. A padlock is used as a locking device, which has a high level of security. After purchasing this shield, you can be completely confident in providing reliable protection against dust and moisture.

Sometimes it may be necessary to purchase a KMA with individual sizes. In this case, you should contact the manufacturer and indicate the dimensions you would like to receive. When ordering such a shield, you must immediately decide on the number of electrical devices that will be installed.

Now you know what the floor board looks like, which is installed on the landings of most multi-storey buildings.
We remind you once again that it is not recommended to carry out electrical installation work without experience. It is best to contact professionals who will quickly complete the installation. We hope this information was useful and interesting. No tags for this post.

Selecting a contracting company

When planning any work, people need cooperation with a company that they can trust to resolve issues that arise during the work.

When choosing a contractor company, you need to follow some rules.

1. Conclude an agreement

Companies operating legally must themselves offer to draw up an official document that confirms the existence of an agreement on the scope of work, delivery dates, cost, guarantee and other conditions. Having an agreement will help avoid protracted and complex resolution of problems that arise.

2. Study information about the timing of work in the market and the experience of the organization. Companies with extensive experience in the same field probably have a large portfolio, which means that you can safely trust this organization.

Information about completed work is posted on the official website, in the company’s office, and you can also communicate directly with the organization’s employees.

You can also check a company by TIN. Just enter the TIN number in the search engine.

Example from our organization: TIN: 18311693 82

3. Read customer reviews

It is important to remember that people can be mistaken in good faith or deliberately distort reality. Try to remain neutral and evaluate information objectively.

4. Prepare your costing/budget carefully

The estimate describes in detail the work that is expected to be performed, as well as their sequence. Based on the calculation/estimate, the final settlement between the customer and the contractor will be made.

5. Ask what guarantees the contractor is willing to provide

When a company provides a guarantee of work, it means that the contractor is confident in the quality of the result, and is also ready to eliminate defects that arise after completion of the work.

Warranty obligations protect the customer by providing a chance to legitimately contact the contractor in situations requiring the elimination of deficiencies. The legislation establishes that the period given to the client to exercise his rights is at least a year (from 12 months).

6. Cost of work

When considering company offers, consider the market price. The price conditions specified in the document must be clear and the cost fixed.

In this article, we briefly talked about the functional purpose, structure, types, classification, stages of installation and connection of the floor panel. An approximate list and cost of equipment for a floor panel for 4 apartments is given. Some rules are also highlighted when choosing a contractor company.
