How do we send an electrician to a banyata
Day, once in a banyata imash, the lamp itself with a lit chick and a single contact from an electrical outlet, sa sank into oblivion. Tazi flock in the present time, performing a few functions and yama enough to pass, for the sake of having an armor on a bitovite uredi, install it in it. Ty kato area on banyata e Malka, ty vinagi ima high humidity. Therefore, the electrical cable is in the banyata trebva and dissuaded by strict research on the rules and disperse.
Containment: 1. Choice for mounting method 2. How can we choose cable and other consumers 3. Wiring diagram 4. Where and install contacts, keys and extensions 5. How yes osigurim electrical safety - RCD and other methods 6. Conclusion
Choice per installation method
Let us first choose the method for installing on the electrical cabling, we will analyze which categories of danger from currents, the blow includes a bath in accordance with the regulatory documents.
Namirame in PUE paragraph 1.1.13. Then say:
Figure 1. Point 1.1.13 from PUE
Spore tazi classification banite sa classification kato dangerous zone. Therefore, when the planer is electrically cabled, it is laid in the walls, on the tavana, etc., to assess the electrical safety of the device. For now, see paragraph 7.1.40 of the PUE. Here, write for start on the cables.
Figure 2. PUE p 7.1.40 back kjm sdzharzhanieto ↑
How can we choose cable and other consumers
Point 7.1.48 of the PUE defines the exemption for contacts in baths and similar rooms.
It is also necessary to install a lighting device in a shower cubicle or in a bathhouse, it uses lamps that do not exceed 12 V voltage.
Switch and contact the switch and protect the water flow from different levels: IPx4, IPx5. All metal surfaces in bathhouses, which, when the conditions are determined, can be subject to voltage (the body is electrically protected, the body is for a bathhouse, mivki, shrangov for supplying fuel and cold water and similar communications), and the earthing bus is a ripple and a system for leveling potential.
Figure 4. System for leveling the potential
It is necessary to take all foreseen research on SP 256.1325800.2016.
Figure 5. Research on SP 256.1325800.2016
In order to organize a system for equipotential bonding, choose a multi-stranded single-stranded conductor PV-3 with a cross section of 6 mm². Toy ima is a necessary gavkavost when connecting to electrical goods.
Wiring diagram
Once you repair the bathhouse, own it at the right place, in the first place, they will draw up a diagram on the cabel. For yes, send a friend, tryabva and decide which consumers for electricity should be installed in flocks and how clarification is organized.
Figure 6. Scheme on the wire
Next, draw up a diagram for the design on the electrical circuit and electrical conductors, try and leave on the diagram for the connection to the conductors in the diverter section.
Behind the electrical contacts of the circuit on the connection of the ripple, yes, it is somehow shown in figure 7.
Figure 7
When tied to the lighting of the body, it is cabled in the deflector cutia and tied in accordance with figure 8.
Figure 8.Scheme on the connection for the connection on the body lighting
In figures 7 and 8, phase the conductors of the marking with the letter L (byala), the conductor is zero working - the letter N (syn), the conductor is zero protected - PE (yelt or yellow with green ivitsi).
Where and install contacts, keys and extensions
Shower or banite sa division into zones for electrical safety. Ima generally 4 types of zones. Abstracts of the citation for reference to section 701 on GOST R505071.11-96.
Figure 9.GOST R505071.11-96
The zoning in the PUE is not described in accordance with GOST R5057.11-96. At the moment e from the value of the other version is GOST R 50571.7.701-2013. Here zone 3 is not included in the regulatory document. Regardless of the tov, that presence in the statute, for yes exclude contradictions.
Zoned e is shown in figure 9.
Figure 9. Distribution by zone per bath
Depending on the zone for electrical safety, the choice is made for protection for cables and other electrical equipment. Theses for the search for a garden for a day at point 7.1.47 from PUE. For the sake of clarity, those are generalized in the table.
Masa 1. Used electrically uredi depending on the zone
For yes, an electrician can be banned and dissuaded from asking for safety, tryabva and all the time, follow the arguments:
- Distribute kutia se montirat from outside banyata.
- Nay-dobriyat option for the location of the switch for clarification is from the outside, close to the entrance.
- For each group of electrical consumers, there is a separate prekvachi or RCD.
- It is necessary to put an electric cable in the wall under the tavana. It is heavy on the hearth, but line, water to get out, and strictly perpendicular to the hearth.If you plan to install it on a cabled or open cable, you can also use all precars electrically wired.
- Vsichki kontakti or klyuve in the banyata sa montirani at least 60 cm from the water source. Depending on the location, it will be subject to the foreseeing the examination of the normative and technical documentation regarding the distribution of electrical equipment in the area. Te sada give in the beginning to the statiyata.
- If necessary, electrically connect the wires to protect the cable, do not let them crawl into zones 0 and 1. If you fall into a banya, you may receive a shock.
How yes osigurim electrical safety - RCD and other methods
For yes, the security guarantor is safe, tryabva and if the correct cable is chosen. Tova beshe discussed at the beginning of the article. Priority in choosing a method based on a cable is given to a method.
Without open cable lines in zones 0 and 1 for banyata.
Once you install the electrical cables in the bathhouse, open them first, pull the cables in order to protect them from mechanical damage. Do not use metal pipes and rakavi. For the prevention of damage, they will use rakavi or corrugated pipes.
Illuminate the lines and line, where you make contact, to protect against various interruptions. All foreseeing the installation on the power of consumers for electricity, they will also be connected through separate lines. Contact, mount in a bath, connected via 30 mA RCD or isolation transformer.
When installed on a 12V lighting line, all devices are cabled separately from the 220V conductor. It is allowed to install a 12V switch in the bathhouse. 12 V will protect the hood block and if it is located outside the banya.
In the apartment, there is a separate prekvach for zahranvane for banyata.Trace tasi machine tryabva and install separate machines, which protect the power and chains, lightening, contacts. If it is necessary, comrades, allow me to remove it from storage in a ban in case there are problems with the cable.
Conclusion
Whenever you rule the electrical cable in the banyata, you own it, tryabva and remember for osigurevaneto for electrical safety. Not by yourself, but if you are a member of the family, then you can get a current blow. Checking on the apartment from the supervising authority for electrical safety is not all perverted, therefore, there are excuses for the rules of this organization on the electrical cabling, carry it from the negotiators.
For yes, prevent irremediably, tryabva and se spazvat izkvaniyata on the regulator and technical documents.
