Electrical wiring: the details you need to know

There are subtleties in any case, and wiring is not an exception, but rather a rule. And this is a case in which rules have a special meaning, although many experts treat them with disrespect. Let’s consider details of power lines in an apartment or house, it will help to estimate work of professionals.

Colour marks and the basic scheme are obligatory details

Any electrical wiring starts with a circuit diagram, the first one being the flat panel. It is desirable that this circuit be glued to the door of the panel. 

  • While the separation of circuits is one of the rules, of which there are many:
  • Separate circuits are recommended for lighting (1 room – 1 circuit) of powerful consumers. Another type of contour is recommended for the bathroom. Separate circuits for room sockets are also recommended;
  • If no electrical wiring boxes are used, the lines are laid in horizontal and vertical directions with deviations from the ceiling and skirting board lines;
  • The brush, divider and junction boxes shall be located in places convenient for inspection and repair.

As a matter of fact, this is a squeezing, before the wiring diagram is made in the apartment, the rules are usually read. We agree that this is not the most entertaining reading, but with all the nuisance these rules contain a lot of useful information. In addition, understanding the employees that the customer knows the rules will make them do a lot more thorough. There is also a pipe for electrical wiring crossing the walls and much more. For example, a shield is marked, with indications of what kind of automatic protection for which circuit is responsible. Colour markings will be observed. By the way, ignoring the color coding is almost the main mistake of non-professional electricians.

Before you create a schematic diagram, you need a schematic device

A good wiring diagram in the house begins with a sketch (project) of the arrangement of furniture and placement of electrical appliances. This approach allows you not only to get a schematic diagram, but also to accurately determine the number of materials, length of lines and assess the required input power. The point of entry and the allocated power is the second main point before the creation of the schematic diagram of electrical wiring of the house or apartment. None of the electricians are interested in how many or what devices you will have to work. They are interested in quickly drawing lines, connecting dots, handing over the object and getting money.

It is important for the owner that the lighting does not blink, the devices work without malfunctioning and the automatic protection system does not engage in false shutdown circuits. Without a “consumption card” at hand, it is impossible to assess how reliable the power system of a separate apartment or house will be. The lack of a clear plan of action does not even cause errors, but terrible misunderstandings, otherwise it can not be called in any way.

One of the reasons for the lapses in physical laying of lines is the owners’ attempts to save money. Unhealthy agiotage of demand for work with electrical wiring can cause not only a desire to make money, but also creative findings in the formation of amateur estimates. The basis of such “creativity” and inflating the cost of works is our illiteracy and a certain piety in relation to the electrician. Therefore, we can easily be convinced that the “company with experience” guarantees quality. Then the plastic degrades, condensation is formed in the voids and the cable insulation starts to break down. So if you need the service of light installation nyc, it is important to involve experienced professionals.
