Chaos in the electric shield is not just an inconvenience, it is a direct threat to the safety of your home and appliances. When each circuit breaker performs its function, but none of them are signed, finding the right switch in an emergency becomes a dangerous lottery. That's why. shielding It is a mandatory stage of completion of installation work, which cannot be ignored.
There are many ways of identification: from simple stickers to complex mnemochems, but the most affordable and effective method is the use of standard mnemochems. signature-sheet. This allows any family member or electrician to quickly orient themselves as to which machine is responsible for what, whether it is a machine or a machine. rosette in the kitchen or lighting in the bathroom.
In this article, we will discuss how to correctly design a shield, what standards exist and where to get ready-made templates for printing. A properly filled out scheme will save nerves and time during scheduled maintenance or sudden maintenance. power outage.
Why do I need to mark automatic switches?
The lack of clear navigation on automatic machines can lead to serious consequences, up to electric shock or failure of expensive equipment. When you see a flashing light or smell a burn, you need to understand in seconds what kind of light you are looking for. switch-off It's responsible for the problem area. If the shield is not signed, chaotic attempts to turn off "at random" begin, which at best will lead to a complete shutdown of the house.
In addition, the marking is necessary for compliance rules of technical operation electrical installations. According to the rules, all switching devices must have (designation) indicating their purpose. This requirement is relevant not only for industrial facilities, but also for private households, where the load on the network can be significant.
⚠️ Warning: Never rely on memory or the “feeling” of the machine. Over time, even experienced electricians forget which switch is responsible for what, especially if the shield is assembled long ago.
Use of special use plate or printed diagrams allow you to structure information. You can see where the protection is. short-circuit It's air conditioning, and where it's boiler. This is especially important if the house is home to elderly people or children who may be confused in a stressful situation.
Use moisture-resistant paper or lamination for tables if the power panel is in a room with high humidity, such as a garage or boiler room.
Standards and requirements for group designation
When filling out a table, it is important to adhere to certain logic and standards so that information is read instantly. In a professional environment, it is used franchising and symbols that are understandable to electricians, but they must be deciphered or obvious to the owner of the house. For example, "C16" means an automatic machine with the characteristic "C" and a nominal current of 16 Amps.
There are several approaches to naming groups. The simplest - by room ("Kitchen", "Bedroom", "Hall"). More complex and correct - by type of load ("Rosetteki", "Light", "Air conditioning"). For powerful consumers, such as electric stoves or floor-floorIt is better to specify the specific name of the device.
- 🔌 Rosette groups - are designated as "Rosettes" or "Roses" with the indication of the room.
- 💡 Lighting Often labeled as “Light”, “Light”, or “Light”.
- ❄️ Climate engineering - Air conditioning, ventilation, split system.
- 🍳 Powerful consumers - "Stove," "Stove," "Boiler," "Brewing."
It is important to consider color coding if you use colored stickers or markers. Red is often associated with emergency or important chains, blue with ordinary outlets, and yellow with lighting. However, the best contrast text works on a white background, which is read even in poor lighting of the corridor, where usually located. powershield.
How to create and fill out a table for a power shield
Creating your own table is a creative process, but it requires accuracy. You can draw a diagram by hand in a notebook, but it is much more effective to use computer programs or ready-made templates in Excel. This will make it easy to edit the data and print a neat A4 or A5 document, which can then be embedded in a plastic file on the door of the shield.
The table must necessarily contain columns with the number of the machine, its nominal value and description of the load. It is also useful to add a column with the type of device (AB, RCD, Difavtomat). This will help to quickly identify the device if the shield is mixed-fitting from different manufacturers.
☑️ Filling in the marking table
Use clear abbreviations when filling, but avoid excessive detail. The phrase "Rosetteki kitchen left wall" can be too long, it is better just "Rosetti kitchen". If there are many machines, you can use the numbering of rows (A1, A2, B1, B2), which is especially important for large switchboard In cottages.
| No p/p | Nominal | Type of device | Appointment (Team) | The premises |
|---|---|---|---|---|
| 1 | C6 | AV | Lighting | Corridor, Kitchen |
| 2 | C16 | AV | Rosettes | Living room |
| 3 | C25 | AV | Air conditioner | Bedroom. |
| 4 | AC 40/0.03 | CCD | Protection of the group | Bathroom |
| 5 | C32 | AV | Electroplate | Kitchen. |
This structure allows to cover all the main parameters. Be sure to include the date of the last check or schema update in the corner of the document. Electrical networks tend to be upgraded, and updated materials are the key to your security.
Ready-made templates and programs for printing
There are many online solutions that will save you time. Electrical manufacturers, such as IEK, ABB, Schneider ElectricThey often offer software packages for designing shields, where marking is generated automatically. However, for the simple user, ordinary office packages are enough.
The most popular format is Excel or Google Sheets. You can download the template, enter your data and immediately send the file to print. The advantage of spreadsheets is that they are easy to scale and change the font, making it large and readable even for people with a high level of visibility. poor vision.
⚠️ Note: When printing, use only a laser printer with a quality toner. Inkjet printing can float from moisture or burn out in the sun if the shield is standing at the window.
There are also specialized online services and applications for electricians, allowing you to create a mnemochek shield. You just drag and drop virtual modules onto a rake, sign them and get a ready-made PDF file. This is the perfect option for those who love visualization and accuracy.
Where to look for free templates?
Search for files on the "excel" or "label template for circuit breaker" labeling templates. Many electrician forums share their experiences for free.
Materials for durable marking
The choice of material for tablets is no less important than the content of the text. Ordinary paper will quickly become useless: it fades, turns yellow and tears. For long-term use it is better to use a self-adhesive film or special label-printersThey are printed on heat-resistant tape.
If you use a regular printer, be sure to laminate the sheets or put them in transparent files with a hard base. This will protect the text from dust, dirt and mechanical damage. Professional shields often use engraved plates made of plastic or metal, but for a home this may be superfluous.
For temporary marking or testing of the scheme, special markers for electrical installation are suitable. They have a thin sting and persistent ink that is not washed with your fingers. However, remember that handwritten text is harder to read from a distance than printed text. font.
- 🖨️ Laser printing on thick paper (minimum 120 g / m2).
- 💾 Lamination - a mandatory stage for protection from burnout.
- 🏷️ Self-adhesive labels - convenient for sticking directly on the plastrons.
The durability of the label depends on the quality of the print and protection from external factors. Lamination is the easiest way to extend the life of your circuit.
Typical errors in the design of the shield
One of the most common mistakes is to use too small a font. In an attempt to fit everything on one sheet of A4, people write text that cannot be read without a magnifying glass. In an emergency situation, when the count goes on for seconds, this is unacceptable. Large print And clear headlines are your salvation.
Another mistake is the lack of reserve seats in the table. If you plan to add another machine in the future or replace a single-phase machine with a three-phase one, there should be space in the table for this entry. Otherwise, you will have to re-do the entire document.
They also often forget about enter-machine and general RCD. These devices are key and their position in the scheme should be highlighted. It is not clear which switch de-energizes the whole house, and which - only one branch, can lead to erroneous actions in case of fire or leakage.
⚠️ Note: Do not use abbreviations that are only clear to you. In a year, you may forget what the “R” means. gr. 2nd Room" and that will create confusion.
Avoid using complex technical terms where simple words can be used. Instead of "Differential automatic switch with a leakage current of 30 mA", it is better to write "Bathroom protection 30mA". Simplicity and clarity are the main criteria for good navigation in the electric shield.
Can I use regular Scotch to fix the plates?
Using regular stationery tape is not recommended. Over time, it turns yellow, dries and peels off, leaving sticky marks. In addition, under the influence of temperature inside the shield, glue can flow. It is better to use specialized adhesive bases or file pockets.
Do I need to sign the RCD and difautomats separately?
Yes, I will. UZO (device of protective shutdown) and difautomats perform a critical function of protection against current leaks. Their labeling should clearly indicate which group of consumers they are protecting so that when triggered, the problem can be quickly localized.
How often do I need to update the electrical circuit?
The circuit needs to be updated every time you make changes to the electrical wiring: add a new outlet, change the machine or connect a powerful device. The relevance of documentation is the key to safe operation.
Where is the best place to place a table with symbols?
The best place is the inside of the door of the electric shield. There, the scheme will always be at hand, protected from dust and not lost. If there is no room on the door, attach the file next to the shield on the wall.
