Rozrahunok rethread the dart

⁰

Peretin drotu respectfully pick up the team, who independently conduct electricity to the booth.

Depending on the correctness, it is necessary to lay down the uninterrupted supply of strum, the risk of victorious failures, the stability of the work of outbuildings, as well as the safety of the sack bag, which is important for human life.

If you take an inconsequential wire, so that you incorrectly choose a resection, you can blame the following remarks:

the cable is overheated;
high temperature leads to melting of the insulation;
є risik viniknennya;
it is possible to burn;
attachments, which are used in the form of a fence, can burn out during the process of exploitation.

How to choose darts?

Trivale admissible strumov navantazhennya - tse smut, on shlіd zvіd zadati vagu pіd an hour to choose a dart in the store.

The leather look of the dart is to be delivered from sales with a passport, all data must be specified.

What is a long-term admissible ambition? Tse is the maximum constriction of the tensions of the outbuildings, yakі spozhivayut strum.

If the boundary is overdrawn, the operation of the wiring is unacceptable.

Also, it is logical to admit that for the repair of the necessary repair, we will need to replace the tightness of the accessories, attachments and other items, as they work out of the energy savings (it is necessary to replace the main chargers for telephones).

It is quicker to mount the wiring with a margin of maximum throughput capacity, and the repairs will be more difficult, imovirno, not for one river, but every year and fit tighter, and buy more, sing-song, if you want.

Speaking about the efficiency of midi or aluminum in the choice of cables for electrical wiring, it is safe to say that aluminum can have a greater number of advantages on aphids midi. On yoga, the melancholy can be recognized:

st_yka to mechanical poshkodzhen;
when peregina does not lamae;
mitzna;
gnuchka;
daily oxidation;
If you mix copper and aluminum in operation, then two different darts with the same tread can let through a different energy supply. Zvichayno, I play against the opposition for the right of the superior component of the medium.

If the most powerful extensions are planned to be connected to different sockets, then the cut of the darts may be 2.5 mm when navantazhenni, as we were wired on the butt.

For any high-voltage display, attach to one outlet (or put it in one room, then 4-6 mm is an ideal solution).

However, for kіmnati, de not pratsyuvatimu nadto strong prilady, sufficient 1.5 mm peretina for all applications.

So you deserve a rose. Do you need help with the scheme:

As a rule, the main thing is that an apartment has two rooms, that it is possible to live with electricity, tse:

boiler. The most advanced accessory, but not all. If you have a gas water heater installed, but in the future you are planning to switch to a boiler, rather than immediately check that the wine is close to 2000 W;
prask. Even if it is turned on infrequently, but it saves a lot of 1700 W, which is a significant increase in the volume of energy flow when it is turned on;
electric kettle. Save 1200 watts. Kitchen attribute of a practical leather apartment;
dirty car. Mabut, one of the leaders in the energy fence. Spozhivaє 2500 W;
mikrohvilova pich - the intensity varies, but in the middle it becomes 700 W;
gunpowder Approx 650W;
computer. 500W;
light. 500W;
fridge. 300W;
current TV. 140 W.

Important: є energy-saving attachments, but zvichaynі. The radiators, which look the same, can be significantly charged for the equal reduction of energy, but on the box or the passport, before the accessories, the data of the shoes are indicated as a rozrahunka;

Rozrahunok peretina dart for phase merezhі

For single phase

sumuёzhnіst vsіh pristroїv, yakі vikoristovuvatimutsya near the apartment;
multiplying the amount by the one-hour coefficient (the whole display is corrected, based on the average data about the one-hour inclusion of a number of outbuildings, and becomes 0.75);
otrimane the number is divisible by the voltage in the measure (ours has 220).

Rozrakhovuyemo in such a sequence:

Zagal formula looks like this:

Wire cut table

In order to determine the admissible interest for the singing dart, it is necessary to carry out an examination of the resection of the dart, it is enough to compare the data taken from the already prepared tables.

Well, it’s true, it’s rich to lay a lot of money, depending on what kind of wire is victorious.

For medium darts:

For aluminium:

Important: if the cable is made up of 4 or 5 cores, the result is multiplied by a factor of 0.93.

On you you can find out all the help of the right professionals.
