How to ground computer

Not in all apartments or houses are modern sockets, which are equipped with a third side contact for grounding. In this case, when connecting the system unit to a regular outlet, there is a risk of injury when the device malfunction or the equipment will suffer from voltage jumps. The computer needs to be ground to protect yourself and components. Let's look in detail how to do it.

The role of grounding PC

Grounding is required for several reasons. All of them are important and help preserve in preservation not only the condition of the equipment, but also their lives. Here are a few moments for which this process is worth performing:

1. Most computers have a metal housing or block with such inserts. If suddenly there is a short circuit or another malfunction, the current will take place on the grounding wire, the man locking from getting an electric shock.
2. Often in apartments or houses occur voltage jumps. Because of this, almost all household appliances suffer. The grounded computer remains unharmed after such drops.
3. Any electrical device emits electromagnetic waves and static voltage. It sometimes accumulates in the metal case of the PC, which leads to a harmful effect on a person. The protective circuit takes the current, making the device safe.
4. When using a microphone, frequent phenomenon is the appearance of background noise. When conducting grounding, they should disappear.

Invalid grounding methods

Sometimes some users are trying to manually carry out a protective contour not the most reliable methods, which leads not only to raising the risk of a computer breakdown, but also increases the level of danger to humans. Consider several prohibited grounding methods:

1. Fastening the wires on the heating battery. If you welcome the grounding cable directly to the heating pipe, it will lead to a breakdown of the computer.



2. Connection with a gas pipe. This type of ground is even more dangerous, since the risk of explosion of the entire gas system increases, which carries terrible consequences.
3. To the thunder. Connecting the protective circuit to the lightning resulting will damage all your components.
4. Connection with zero cable. This method of connection is not safe for the user, because at any time the phase with a voltage of two hundred twenty volts can get to the system unit, which is deadly for a person.

Ground the computer in the apartment

In many high-rise buildings, the distribution of electricity occurs on the same scheme that you can observe in the picture below. Conduct voltage with four wires, one of which is zero. It is grounded on a separate substation. Install the ground in such a system is the easiest way to use the installation of an additional conductor. This is as follows:

1. Buy the grounding cable of the required length and pave it from the apartment to the distribution shield. It is best for carrying out such work a wire with a large cross section, stranded and made of copper.
2. In the shield you need to find the area where many conductors are screwed to the metal plate.



3. In a free place, fasten your cable with a bolt or self-tapping screw. Before this it is more correct to clean the end of the wire, it will be more reliable.
4. It remains only to attach the other side of the cable used to the computer case or the contact of the socket. When connecting to the system unit, use a threaded connection.

It is important not to connect the copper wire to aluminum - so contact will quickly collapse and wiring can occur.

Ground a computer in a private house

If the same electricity supply system is implemented in a private house, as in the apartment buildings, then the algorithm for the grounding is no different. However, most often in such real estate the transmission of current is made according to a single-phase diagram. In this case, you need to mount a separate protective circuit. Now there are already ready-made sets in many stores, so this process should not be called difficulties.

We just need to stick in the ground a metal pin to the depth of about one and a half meters and secure the ground wire on it. The second end of the cable is moving to the system unit and connect one of the methods described in the instructions above.

Of course, it's not so difficult to ground, but if you do not have any knowledge of electronics and are not sure about your abilities, it is better not to try for this business. Trust it with a professional, so everything will be successful.
