Power supply of beauty salon

Explanation of the project

This project is performed on the customer's tasks, technical conditions issued by the Tiraspol Non-Profit Partnership "Textocom" and the architectural part of the project in accordance with the current norms and rules.

The project considers electric lighting and power supply of the beauty salon at the address Tiraspol, st. Odessa 145, apt. 89.

Project Master Data:

Thrust reverser = 12.6 kW

PP=7.5 of kW

IP = 14 A

Category of power supply reliability - 3.

Electricity metering is provided by the three-phase counter of live broadcast SA4UI678 20A installed in panel board in BZUM box on 1.5 m from a floor .

In the existing VR14810, install an additional group of fuses such as PN2100 from which to power the beauty salon.

The main consumers of electricity are:

Electric lighting.

Sockets.

Exhaust ventilation.

Air conditioners.

Installation of lighting fixtures and electrical sockets is performed according to design design. Lighting fixtures and electrical installation products are selected in accordance with the functional purpose of the premises, their degree of protection corresponds to the nominal voltage and environmental conditions .

All sockets are accepted for hidden installation on 16A with grounding contact. Lighting and power circuits are made by wire

PVA 3 × 1, 5mm2, PVA 3 × 2, 5mm2 and PVA 2 × 1, 5mm2. The wire is laid in a corrugated pipe with a diameter of 20 mm. The wire is laid in the voids of the floors, in the bars of the walls, behind the suspended ceiling.

The height of the switches installation is 0.8 m from the floor. Socket sockets are installed at a height of 0.8 m from the floor, socket sockets for air conditioners are installed at a height of 2 m from the floor.

The lead-in cable AVVG 5 × 6mm2 from the AVVG from the floor panel to the distribution board is laid hidden along the walls in the stroke, from the metering board to the AVVG storey panel 4 × 6mm2 in the plastic cable channel at a height of not less than 2 m from the floor, from the VRU and AVVG metering board at a height of not less than 4 × 6mm2 in the wall.

Protective safety measures.

In relation to the danger of electric shock, the premises of the object are referred to as rooms without increased danger.

To protect maintenance personnel from electric shock, all metal non-current-carrying parts of electrical equipment (boards, lamps, etc.), which may be energized due to possible insulation damage, must be grounded by connecting to a zero wire of the electrical network. As a grounding conductor, use special protective conductors (as part of the cable) with a section equal to phase, connected to the PE terminal.

To increase the safety level, it is provided to install the RCD before entering the RB with a differential leakage current of 30 mA shutdown, with built-in overcurrent protection.

Installation Instructions

All electrical installation works shall be performed by a specialized organization with the requirements of the existing PUE, PEEP and SNiP.

Protective conductor (PE) shall be connected to protective contacts of sockets, lamps and equipment with metal housing. When supplying sockets of one group line, the branches to each sockets must be made at the branch points in soldering boxes.

Connection to distribution board for common contact clamp of zero and protective conductor is prohibited. Wiring shall allow easy recognition along the entire length of the conductor by colors.

Built-in lighting fixtures with matte glass grade SV398 with halogen lamp 220V 10W are designed to illuminate the ceiling and are embedded horizontally in the side wall of the ceiling.
