How to make grounding in the Khrushchev

Additional grounding may be required in order to get rid of low frequency hum at 50 Hz. A roar "leaks" in the audio path and interferes with the normal perception of sound mixing console, guitar or computer. In addition, grounding is required when installing household appliances – washing machines, electric cookers, etc.

You will need

• - thick multi-strand cable;
• - screws;
• - washer;
• - metal rod or crowbar;
• - drill;
• cutters;
• - pliers;
• - screwdriver;
• key from the electrical panel.

Instruction

1. If you live in a two - or five-story house built in the mid-twentieth century (the so-called "Khrushchev"), try to find near the landing Board. He may have closed. In this case, consult your responsible for the flap to residents or electrical housing Department and take the key.
2. If the shield is grounded, reaching for him out of the apartment. Take a thick stranded cable and route it from the appliance (or sockets) to the electrical panel. Open the shield and find the place where the body is bolted a lot of wires.
3. Strip the cable end 2 to 3 cm, divide the braid into two pieces, insert between them a screw (for a tighter contact can get him the puck). Using the pliers twist the ends of the braid, creating a tight circle. Screw the screw into the hole located in the electric panel so that it sat tightly enough.
4. The other end of the cable is also clean. In the computer, washing machine, cooker or other equipment, find a place to ground back to the metal chassis, and attach it to the wire by a small screw. Generally, the location of grounding is indicated by the inverted "T" with an additional hatch at the bottom or Ground (GND). Perhaps next to the icon you'll see a clip or special attaching bolt.
5. In order to ground the outlet, connect the cable to special third contact intended for this purpose (it is in all European sockets).
6. If you are found in the entrance of the electrical panel with the possibility of grounding, go down to the basement. Often grounding in the Khrushchev is at the opening switchboard, located in the basement. In this case, route the cable from his apartment to the shield (the keys to the basement and Board-ask in the office).
7. To the first floor there is another option – remove the ground wire through the window. Take a metal rod with a length of 1.5-2 meters, for example, scrap, with one side drill a hole for the screw. Hammer the rod into the ground with sledgehammers, and in the remaining part of the screw the screw with the twisted wire. To improve the conductive quality of the earth, dissolve in a bucket of water, a pound of salt and pour it into the place where I buried the pin.
