Establishing electricity in homes
(Part 1)
Electrical installations and stages of establishing electricity
Plastic transit chart.
Electrical work (increments) goes through a few stages, and these stages are considered to be alternate with each other.
The basis of the electrical installations in the house, for example, the quantity of electrical circuits of the house, the areas of switchgear, the power plug, the concentration of ceiling and wall lighting, the quantity and concentration of electrical wires per circuit, the type of circuit breakers and the estimate of the entire electrical limit of the house. ask us
We reach the stages of work towards the proper steps for electrical installations for once in a lifetime, not to return to anything that has been mastered through some steps, and it is basically the stage that we will reach upon completion of the work, so the arrangement is our best assistant because it shows us the beginning and end of the work .
First, the plastic pipes: - through which the electrical wires will pass later, it has not been completely settled in this plastic organization or the places for ceiling lights will be formed, and this organization will be dispersed and these points will be according to what is in the arrangement because it is the beginning, so this is the most vital stage in the implementation, It is the primary stage, and the subsequent stage, which is the foundation, vital, and basic to supplying electricity.

Stages of incorporation of electrical installations:
1- Preparing the paths of the plastic pipes
2 - strapping boxes
3 key boxes
4 - circuit breaker box - dashboard. Ask us
Plastic pipe support stage:
And the plastic cylinders should be placed evenly or in an upward direction, realizing that we can roll the tape because it is adaptable, but it is better that the bends are not too much and this organization should be connected to each other starting from the transfer plate pass through the interstitial boxes, then the switch boxes. Drawing Diagrams electrical
The gauges for plastic cylinders (tees) should be chosen with a width similar to the amount of wire that will pass through any of the raceways for the plastic tubing.

Outline stages:
This is known from the outline diagram, where the amount of wire per circuit or the amount of light fixture per unit is indicated.
Supported plastic pipe sizes for electrical installations (13 mm - 16 mm - 18 mm - 21 mm), and there are larger and more modest sizes as needed.
Secondly, electrical junction boxes (magic boxes):
They are plastic or metal cans of square shape and different sizes as needed.
Among the normal sizes of junction boxes (10b1 0 - 12b10 - 15b17 9), there are larger sizes than that, and there are also circular molded boxes and they can be used for the requirements of many tasks depending on the preferred decoration of the finishes.
These boxes are placed on the walls and the bearings are attached to them, which reduces the distance of the bearings on the one hand and electrical wires are attached to them.
Detailed measurements of standard dimensions for placing magic cans:
The good ways to prepare the house or room are 30 to 40 cm from the surface of the ground, depending on the level of the room, and all the link that confines the house is connected to each other through the plastic tape and feeding the switch boxes and at the end it reaches the electrical panel that will take care of the relative number of corners of the house.
Depending on what is displayed on the arrangement, to keep away from pointless irregularities.
Thirdly, the intersection boxes and switches designated for electrical circuits (light current boxes)
With regard to the impeded flow, which is telephone lines and the Internet (TV), there will be regulation of expansions and plastic boxes. Electrical wire boxes and switches bound to set the telephone attachment and receiver wire inserted at a level of about 60 cm to 70 cm from the outer layer of the tiles; Rectangular in shape, they are presented at a level of about 160 cm from the outer layer of tiles, and they are of few sizes and according to the number of circles (cutouts), and some of them have a maximum of 8 shapes.

Fourth, the main case for breakers Some of them have a limit of 12 breakers, some have a limit of 16 breakers, some have a limit of 18 breakers, and some of them are larger than that and more modest than that, and they are selected according to the quantity of circuits and they have a cover plastic that includes many structures, and this is the stage of starting work in the electrical installations and it is a network Expansion plastic that is screwed into the wall and before the cladding system of the house (cement mortar).
The plastic net is finished and taken care of (bonded together) and stretched well and neatly.
For the interface - switching boxes - circuit breakers (dashboard) and the next stage for that and following the completion of the rest of the house work. Ask us
Fifthly, extending and pulling the electric wires for feeding :
It is the stage of extending the electrical wires, several things that we will implement, remembering to calculate the limit by respecting the load for lighting, and the household appliances of the house, and here we will discuss that, but in an improved way, and what we notice here are models through which the specialist can distinguish work strategies for the limit, and by knowing this limit, he can Choosing the appropriate part of the conveyor and the appropriate safety preform, for example:
We have a private house consisting of a few rooms, a kitchen, a bathroom and a nursery. We need to carry out electrical wiring for this house. Single-phase strain (220 volts) We start from the electrical panel and quantify the electrical circuits of the house with the following steps:
1- Lighting circuit for each room
2- The circuit plug for a similar room, thus isolating the lighting circuit from the circuit
3- Electrical circuit for the kitchen
4- Circuits, except for household electrical appliances, model (electric stove - electric water heater - atom, electric washing machine), and many high-load electrical appliances.
