A characteristic feature of the bathroom, in comparison with other rooms of the apartment, is that it has an increased level of humidity, and it is also possible that the elements located on it, including electrics, can splash water onto the wall. Based on this, the installation of electrical wiring in the bathroom is somewhat different from the installation of electrical wiring in other rooms of the apartment. Below, we consider the features of installing electrical wiring and connecting household electrical appliances in the bathroom.

It should be remembered that errors in the installation of electrical wiring in the bathroom, as well as the wrong choice of protective devices, can lead to negative consequences - a person is shocked by electric shock, since electricity and water are incompatible things. Therefore, do not neglect the recommendations and it is better to make the wiring in the bathroom reliable and safe to use ...

Fireproof soldering iron tips require a delicate attitude. In no case can they be cleaned with files or sandpaper, since the protective layer is quite thin, and its damage will lead to an early burnout and wear of the tip. Such stings can only be periodically wiped on a special sponge (sold with other soldering accessories), or on a wet piece of cloth.

Instead of a special sponge, a dishwashing sponge is quite suitable. Naturally, the sponge should be moistened with water. You can moisten the sponge with glycerin (sold in pharmacies), then the sponge will not dry, always remain wet and ready to work.

To clean a non-combustible tip, among other soldering accessories, special tip cleaners are available. This is such a net, not to say a washcloth, made of brass chips in the shape of a ball, into which the sting should be periodically immersed. In this case, excess solder and oxides remain inside the coil...

Modern electronic technology is improving very quickly. The degree of integration of modern microcircuits is such that millions of transistors fit in a single case, but the cases themselves are becoming smaller and smaller. Discrete parts - transistors, capacitors, resistors are also small-sized, lead-free. All this is mounted on boards by SMD surface mounting. The parts are so tightly arranged that it is simply impossible to solder something with an ordinary forty-watt EPSN electric soldering iron.

True, some experts from the soldering iron claim that you can solder anything you want even with an ax. Maybe this is so, but, as they say, not everyone is given. Therefore, it is better, nevertheless, to use a soldering iron, since now there is a very wide selection of soldering tools. And you need to be creative in purchasing this tool. First of all, it is necessary to determine for what work an electric soldering iron is bought ...

In solar energy, batteries occupy a special place, which play the role of an intermediary in the transfer of electrical power to end-users. This can be explained by the fact that the maximum amount of electric energy is generated by the solar battery during intense light exposure that occurs in the daytime.

However, its greatest consumption is carried out with the onset of darkness, when lighting with household appliances is massively used. Batteries allow you to save surplus electricity generated during the day for evening and night use.

Of course, as an option, in the daytime you can turn off part of the working solar modules in the reserve, but this will not solve the issue of evening electricity shortages.Any electric batteries are considered as reusable direct current sources ...

If you have not heard about the COCO home appliance remote control technology, then it's time to get to know it! After all, this is the most affordable and simple system for radio control of electrical appliances and "smart home".

The heart of the simplest version of the system is the AYCT-102 remote control. It contains a radio transmitter operating at a frequency of 433.92 MHz and allows you to control both individual electrical appliances plugged into sockets through radio adapters, or lighting, using miniature built-in receivers, and groups of electrical appliances. For example, simultaneously with several electric blinds or a group of spotlights located in different parts of the site.

The AYCT-102 remote control is designed to operate on 16 channels, divided into four subgroups. This makes it very easy to manage appliance groups ...

A person cannot perceive with his senses: the rustle of electrons running through wires, see the speed of their movement, smell them. We cannot detect electrical energy without special devices, but it can cause great harm to our body. Indeed, a current of 0.05 amperes, with a tragic set of circumstances, causes cardiac fibrillation.

Manufacturers of electrical equipment with energy supply organizations do a lot for the safe operation of electricity. However, it also depends on the owners of the apartments. An example from the life of children. A little boy walked around the room, holding a female hairpin in his hands - an ordinary steel wire. In front of his parents, he stuck it into the openings of the electrical outlet so quickly that they did not have time to react. What happened ...

Everyone knows that the fugenfueller is ideal for leveling walls, sealing joints of drywall sheets, filling various cracks and grooves in the walls, as well as sealing strobe when laying hidden electrical wiring.

Everyone knows that the surface of the walls before puttying must be cleaned of dust. But there are at least two mistakes that even experienced professionals make when using this wonderful material.

The first mistake is made when sealing large grooves and strobe with electric cables having a depth of 15-25 millimeters. Trying to save time, they close the stroba immediately to “zero”, filling the entire volume of the cable groove. When dried, the fugenfueller increases its volume and along the strobes there is a tubercle 2-3 mm high, which in a day to clean off is already very problematic.Since this putty material has a high hardness. Fill in groove...

Various alternative sources of electricity are increasingly interested in homeowners. They are attracted by the low cost of using solar energy. But the mass introduction of devices operating from the solar light flux is constrained by the high cost of equipment and the complexity of its selection and installation. In fact, to assemble with your own hands and operate a solar power station is within the power of a home master, even a senior student. To do this, you need to: familiarize yourself with the principles of operation of the circuit, determine the tasks of the equipment, select the most suitable equipment for the station, conduct mechanical installation of all elements, assemble the electrical circuit, verify operability and correctly operate it.

Numerous practical experiments allow us to recommend a universal scheme for solving the problems of a solar power plant for the home. It includes: solar module ...

There is such a profession in the energy sector: to protect people and equipment from short circuits and other malfunctions in the electrical circuit. The work is complex, highly paid, prestigious.

Only persistent, purposeful and competent people master this profession. They are usually called by profession - relay workers. This is explained by the fact that a very long time in the algorithm of protection and automation circuits uses an element base based on relays, although recently microprocessor devices using computer technologies have begun to appear in large quantities.

Just want to give an example from the life of the substation team with equipment operating under a voltage of 330 kilovolts.How relays cope with their duties can be learned from the sad example of an accident. A repair team led by ...

Electric heating elements are used in household and industrial equipment. The use of various heaters is known to all. These are electric stoves, ovens and ovens, electric coffee makers electric kettles and heaters of various designs.

Electric water heaters, often referred to as boilers, also contain heating elements. The basis of many heating elements is a wire with high electrical resistance. And most often this wire is made of nichrome.

The oldest heating element is perhaps the usual nichrome spiral. Once upon a time, homemade electric stoves, water boilers and goat heaters were in use. Having at hand a nichrome wire that could “get hold of” in production, make a spiral of the required power ...

As often happens, everything turned out quite by accident. A friend asked me to deal with the high power consumption of garden lighting in a country house and its reliability. If necessary, I asked to put a separate voltage regulator for lighting, since the mains voltage is unstable and often low.

About a year ago, an acquaintance already began the struggle for energy savings. He replaced incandescent lamps in garden lights with compact fluorescent energy-saving lamps. The energy savings turned out to be significant when compact fluorescent lamps were installed instead of 21 pieces of conventional 60-100 W lamps. The company did not stint and put "OSRAM" 24 watts. The homeowner arranged a saving result. But over time, the disadvantages of the new lamps became noticeable. For example, a base with electronics for an energy-saving lamp ...

By acquiring property in the secondary market, we are always at risk. Two famous market fools from the saying - the seller and the buyer - are constantly trying to get the most out of the deal. Of course, the benefit is possible only at the expense of a vis-à-vis: the seller suddenly forgets about some of the shortcomings of the goods, and the buyer diligently knocks down the price, hoping to get a worthwhile item for nothing.

And the more expensive the acquired property, the sharper the hidden conflict of interests between the seller and the buyer, the more irresistible the desire to deceive the neighbor becomes and the higher the price of the error. Therefore, the situation becomes extremely extreme if the subject of bargaining is real estate.For example, if an apartment is for sale, then the buyer does not have the opportunity to find out all its flaws for certain. Let's say it's summer in the yard, and in winter it turns out ...
