you need
  • - Screwdriver indicator;
  • - regular screwdriver;
  • - insulated wire with two probes at the ends.
plugged in a table lamp and make sure that it glows.When inserting the plug a desk lamp, do not touch the ground contact sockets, because you still do not know whether it is connected.
Disconnect in the shield machine.Make sure you turn off just the machine that you need, for the extinction of the lamp.
Unplug the table lamp.Remove the outlet cover.
look that is connected to the terminal.If it is connected to one of the terminals of the socket, so you use vanishing.If a separate line - grounding .If it is not connected anywhere - outlet is not grounded.In the latter case, it is possible to include only electrical applianc
es with double insulation.
Put the cap on the outlet tightly secure it, and then turn on the machine.
If a vanishing, check that it is carried out.After all, if you install the socket to the terminal, instead of zero mistakenly hooked phase mains voltage can get to any body incorporated in appliance.This situation is very dangerous.
Using a screwdriver indicator, check to see if the grounding terminal phase voltage.If it is, use this outlet should be stopped immediately and consult a qualified electrician.Even if the vanishing implemented correctly, you should alert the fact of its existence.The fact that not all types of wiring allow its implementation.Therefore, consult an electrician is necessary anyway.
If you find that the outlet is grounded, check whether this is so.First, make sure that the third wire connects the ground contact is not a phase.How to do this and that to take when it detects this contact phase voltage, described above.Then a screwdriver indicator locate the outlet phase.Now, leaving the screwdriver in the phase socket, remove your finger from the sensor.Instead of finger push him one of the insulated wire probes.Neon lamp either lights up at all, or lights up very slightly.Now, without removing the probe from the sensor, press the opposite probe to the terminal.Fingers at the same time, do not touch any metal parts of the screwdriver and sockets.Neon lamp should light up brightly.This means that the ground pin is really grounded.But finally make sure the connection of the contact with the ground is really done safely, is possible only with the help of special devices, so to be sure to contact an electrician still zhelatelno.Esli the bright glow of neon lamps in the screwdriver is not observed, the ground wire is not connected towhat.In this case, should be considered as an ungrounded outlet, and connect it only to devices with double insulation.
