Thorough check and binding in the apartment is the most important stage of repair. It is also recommended to perform this procedure in a situation where there are certain issues regarding its serviceability.
Of course, the easiest method of verification is the appeal to a qualified electrician. However, everyone knows that utilities do not work regularly, and private craftsmen require too much amounts for such assistance. That is why the check can be done independently.
Checking a new wiring
The degree of quality of insulation of electrical wires with increased voltage will depend on the condition of the cable. In other words, you should not regret and buy good material with which there will be no problems in the future.
If there is no confidence in a state of isolation, then the verification is performed by means of a megommeter. It is worth noting that in some construction stores such a service is provided direct before buying.
The further stage of the audit is considered visual insulation control. Any damage should certainly be eliminated until the cable is closed by finishing building materials.
What is required for calling?
This procedure is often carried out through a specialized device – a multimeter. He is responsible for the registration of various characteristics of the electrical connection (voltage, resistance, current strength, etc. p.). At the moment, several varieties of this device are being released:
Digital.
Analog.
Despite the chosen model, the principle of their functioning always remains unchanged.
The process begins with the connection of connections. First of all, the device sets the appropriate mode on the device. In most cases, it is noted using the LED. In the future, you need to go to the call area, in other words, to the distribution box. It is here that you can see several wires that do not have a marking.
It is necessary to find the phase – start the machine, perform a check of numerous wires by means of an indicator screwdriver. It is worth noting that each wire found must be labeled. To do this, just use the ordinary insulation tape.
Then you need to find to find zero. To do this, the device turns on to determine the voltage. When 220V is indicated on the device, this indicates that the desired wire was found. It must be marked.
