Electrical installation work is primarily a responsible measure, on the correct implementation of which the general fire safety and electrical safety depend. But in addition to the necessary knowledge, a professional tool is required to successfully complete the tasks.
Before carrying out electrical work, you need to familiarize yourself with the project and decide on the front of the upcoming work, the sequence of electrical installation of electrical equipment, then you need to choose what kind of electrical tool will be used for electrical installation. The quality of electrical work performed depends on the right choice of power tools, because if an electrician starts to gouge a hole to install an outlet with a hammer and chisel, then the efficiency of such work will be equal to zero.
In hardware stores there is always a set for electrical work . And even if the standard set of tools does not suit your bundle, you can make a list of the necessary tools for electrical work.
1. Combination pliers, or pliers - this is the most common type of hinged-tongue tool, which is used for fixing and fastening various objects. Pliers are also required when working with cables, when cutting or soldering wires. The quality of the material from which the pliers are made is the main indicator of their strength. Pliers are for different types of loads and differ in some features:
2. Tool for removing insulation, may have several constructive types. Its choice depends on the type of cable and its cross-sectional area. These types of tools are necessary when solving time-consuming cable laying tasks, since they significantly reduce the time spent on their implementation. Today, when you can buy a mini-tractor, a rider, or any other garden or construction equipment in a building supermarket, it is useful to remind you that a tool for stripping insulation is equally effective when conducting wiring in a house, and when repairing electrical wiring or household appliances.
3. Modern technologies of electrical installation have led to the emergence of fundamentally new tools, the use of which may indicate the level of quality of the work performed. In addition to several dozen types of sets for crimping cables , there are about a hundred types of individual tools for various pressing operations.
4. A set of screwdrivers and a screwdriver will be necessary when carrying out any electrical work associated with the installation of junction boxes, meters and switches.
Are there any differences between the tools used by professional electricians and the so-called household tools, that is, the help of which the ordinary man in the street does the simplest electrical work at home: replacing an outlet, a switch, connecting electrical appliances, and so on?
Let's start with the fact that no self-respecting electrician will not use someone else's tool - the fitter is simply not sure of its proper properties. Will the insulated pliers withstand the tension? Whether the hand will not slide off the screwdriver stop, - the importance of these issues is understood only by a professional who faces the danger of electric shock almost daily. The danger is real! The danger of electric current is that it is almost impossible to determine in advance the presence of voltage using the senses. If we smell gas or, for example, we can feel heat, then life-threatening stress is not.
Many will say that before the start of electrical work in the apartment completely cut off the power, having secured themselves in this way. But after all, there remains the possibility that the circuit will not be disconnected using a disconnecting device or the power grid is not correctly assembled, as a result of which the voltage will not be removed .
To determine the presence / absence of voltage using a pointer ("indicator") . Those devices of unknown production, which are sold everywhere at a symbolic price, do not hold water! Such a pointer may cease to function at any time, thereby deceiving the possessor and putting his life at risk, or break right in the hands even with a minor mechanical effect.
The difference of the professional voltage indicator is in its reliability. And in the ability to properly use it. Before starting, the electrician will necessarily perform an external examination of the voltage indicator, then check the correctness of his work on live parts that are under voltage. And only after that it will disconnect and re-check the absence of voltage at the installation site. If the voltage indicator drops during operation, you can no longer trust the data obtained with its help - it may be damaged. At first glance, all these actions and remarks are simple, but without skills developed to automaticity, the risk to life remains.
All tools with insulated handles, which is used for electrical work, refers to the main means of protection. In accordance with the Rules for the Safe Operation of Electrical Installations (ПЭЭЭП), a number of requirements are imposed on such an instrument and its use. The simplest of them is the storage of tools for electrical work in a separate bag or case, the purpose of which is protection from external influences. In addition, every six months the instrument undergoes a mandatory inspection, the purpose of which is to identify mechanical damage. Once a year, an instrument with insulated handles is subjected to special tests in an electrical laboratory, where it is tested for resistance to prolonged exposure to increased voltage. The test results are recorded in a special journal, where each protective tool corresponds to a specific number applied to the case.
The tool sold in the markets and in stores does not pass all these tests and inspections. Consequently, its use is associated with a certain risk - this must be realized. Are you ready to risk? Your life, the lives of others? If not, you have two options: to become a professional electrician, or resort to the services of companies in which professionals work. Believe me, there are no trifles in electrical work - the risk is always present!
As a conclusion, it should be noted that when purchasing any power tool (perforators, drills, screwdrivers, grinders, etc.) in the store of construction equipment, you should always ask in advance about the availability of a repair center for warranty service of tools.
