ELECTRICAL PLAN
Power supply
The connector, cable that ends in the cable home metering cabinet with appropriate fuses.
For the introduction of the cable into the building lay-self-extinguishing flexible corrugated tube inner diameter f 48 mm, continuing to service entrance cabinet.
The feed lines are performed in plastic tubes of standard diameter, placed under the mortar or concrete with inset copper conductors or cable insulation P PP. Cross section pojnog water is determined by the load (heating and voltage drop) and the degree elektrificiranosti – standard and type of load per household.
Installation
Overall el. installation of high voltage perform copper conductors in P thermostable plastic tubes (1.5 mm2 to 2.5 mm2 and lighting for the division of power).All installation accessories and supplies be installed in parallel with the development of the construction of the building. Cross section of lighting is 1.5 mm2, while the connectors and special thermal loads, use the guides section of 2.5 mm2. Power cord is (10 mm2).The entrance hall is built as a product distributor, equipped with the necessary number of fuses (circuit).
On the wall below the separator is installed square junction box PS 50, which were concentrated all the circuits.
The bathrooms need to perform bonding of all parts that do not belong to electrical installations such as metal trays, metal drain pipe, metal conduit central heating etc.Potential equalization is done so that all these materials together galvanically connect the water P6 mm2 on a separate bus equipotential which are placed in suitable plastic box.Sockets and switches to turn lights are flush mounted type of micro performance. They are used exclusively connectors with protective contact.
Protection from indirect contact
Protection against indirect contact will perform the TT system.
It must prevent the maintenance of excessive touch voltages on the parts of electrical appliances or installations that do not belong to a circuit, and is achieved by connecting all conductive parts of electrical apparatus with a special protective conductor, which is the main distribution cabinet connects to neutral.
Under current regulations, the protective device which provides protection against indirect contact electric circuit or equipment in case of failure of insulation between live parts and other structural metal parts (casing) must automatically shut off the power supply circuit in such a time that does not allow voltage greater than 50 V RMS, which could pose a risk of physiological effects on people in contact with these parts.Under the terms of the dealer network to which the object is connected applies TT protection system and the application Disconnecting the circuit with an electrical fault that is. energy with breakers RCCB 40 / 0,3 A. Protection against indirect contact for consumers in the bathrooms of residential space, will be performed by breakers RCCB 40 / 0,03 A.
Impendance circuit must be chosen so that in the event of insulation failure anywhere in the installation of automatic power-off occurs within the set time.
The longer the time off that does not exceed 0.5 times the power supply allows for circuits or final circuits feeding the only non-transferable equipment when connected to the switching block that are not connected str.krugovi who require time off 0.2 or 0.4 s.
In accordance with the technical standards for electrical installations of low voltage, in order to protect against electric shock, it is necessary to perform the installation of bonding. For this purpose, will all metal surfaces of building hardware, mechanical and hydro installations and equipment mutually galvanically connected.
In addition to the above provided the equalizing potential of the direct grounding of metal masses, such as metal mass in the toilets that are connected by a specially laid on ground water protection in a box for bonding (TRC), guided P / Fy 6mm2 Cu. Box equilibrium potential to connect to the PE bus tours in the cupboard P / Fy 16 Cu.
Equipotential is bringing the same protective potential (zero) of water and pieces of metal, various installations in buildings.
In order to prevent occurrence of excessive touch voltage installations in buildings due to the introduction of dangerous resources necessary to implement measures in buildings POTENTIAL EQUALIZATION.
The effectiveness of measures to examine the potential equalization measurement. Equipotential is successfully carried out, if the measurement of contact resistance between protective wiring and metal parts of other installations gain value is less than 2 W in any room of the building. For larger buildings it is enough to make measurements in areas that are farthest from where he made galvanic connection, for example, measurements on the top floor of the building.
The effectiveness of measures to examine the potential equalization measurement. Equipotential successfully carried out, if the measurement of contact resistance between the protective wiring and metal parts of other installations gain value is less than 2 Ω in any room of the building. When measuring the resistance I / O method of measuring the voltage does not exceed 50 V, with the current measurement must be greater than 5 A.
Earthing
As the electrode will be used FeZn steel strip 40×4 mm. Tape to lay the foundation of the building.When laying strips, joints leads to perform in critical cases.If determined by measuring the resistance failed, fix it necessary grounding strap length.Measurement of resistance in the run in – and method in relation to a distant electrode.
Equipotential bonding
Equipotential bonding is a central point of the potential adjustment of individual systems. Placed on a suitable location (for
cable connector near the cable connecting the closet or in the composition of the cabinet building (service entrance).
The bathrooms must be done through bonding terminals K-1891 (“Contact”). With these clamps protective line to pass to the installation panels, which are protective bus connects to the central bus bonding.
