Grounding a private house: how to make grounding, choosing the most effective system

Building a home without a projected grounding is at least reckless. If there is a problem in the wiring of household appliances, it will harm the residents of the house. The insulation problem will lead to the passage of electric current inside the building to the electrical installations, and this threatens with unpleasant consequences. How to properly make grounding for the safety of your home can be found on the website .

How to make grounding in a private house according to PUE and why you need grounding

In your home’s electrical wiring system, grounding is one of the main safety functions. And many do not know what grounding is for at objects. In the event of a breakdown, the power system provides the path of least resistance, it ensures that the current flows back to ground. This reduces the likelihood that a short circuit will cause a fire or life-threatening shock.

The final and important part of a home’s power system consists of a metal ground rod driven deep into the ground, a wire that connects this rod to the ground lug of the service panel or utility meter base, and a connector clip between the wire and the rod. How to make an energy system in a private house – you can see in the picture.

The grounding of electrical installations is an essential part of the electrical system. It is this that ensures the safety of residents, electrical equipment and appliances. Grounding of a private house according to the PUE – the resistance is set to no more than 25 ohms. This will require more than one ground rod. They are the same electrodes used to connect the power system with electricity. They are made from a variety of materials, however copper is the most common raw material used for residential applications. Ground rods are good conductors of electricity; they allow current to flow into the ground, eliminating danger from you and the electrical panel.

The ground rod that connects the home power system to earth is a copper metal rod combined with galvanized iron or stainless steel.

Ground rods come in lengths of 2.5 meters and 3 meters, the former being the most common size used in residential applications. As a rule, grounding rods should not exceed the established rate. In dry soil, which provides more current resistance than wet soil, the ground rods are folded and clamped together so they can extend deeper into the ground.

Another option is to add a second ground rod. As a rule, this is the best option, according to the PUE, to place the grounding of the rods at a distance of at least 1.8 meters. If possible, they should fall into damp ground around a private house.

It is unwise and unsafe to install short ground rods that are sold to ground TV antennas and other devices. Their use is not legal for household power supply, as it causes a power failure.

DIY modular and portable grounding of a private house

To avoid electric shock to occupants using the device, each outlet must be connected to a power outlet. But this only works if all the sockets are connected to a special circuit that is submerged in the ground outside the residential building.

There are two types of grounding in a private house, which differ in function. An equipment power system is a network of bare wires that are routed through a house as part of a wired, branched circuit. They connect to a transformer outdoors and protect homeowners from electrical shock in the home.

The power system connects your home’s electrical system to the ground. Modular grounding helps to safely dissipate unexpected electrical charges from other sources.

Power grids also help discharge static electricity. Their accumulation in electronic equipment such as home computers can create operational problems. This is a less important function of the grounding conductor, protecting equipment and not people. Therefore, the answer to the question whether grounding is needed in a private house is unequivocally positive. Since without it, you will be protected from the effects of current. How grounding works on equipment can be seen in the figure.

Modular grounding is used for the installation of grounding equipment:

It is a set of prefabricated structures, which consists of interconnected steel pins one and a half meters long. Benefits of grounding include the ease of installing the electrode to a depth of thirty meters without special equipment. Installation is carried out by one person. If you do not have experience in how to make grounding in a private house, contact a specialist.

Portable grounding includes a special product that is used to install the grounding of individual sections of installations. The main function is to ensure the safety of specialists during repair work. The portable grounding structure consists of the following elements:

Installing grounding in a private house is a serious business and requires responsibility. Most home owners can handle the installation of a power system. If you do not know how to make protective grounding with your own hands, we recommend that you contact a specialist .

Do-it-yourself grounding is difficult to install without knowledge, experience and details.

  1. The ground wire is the link between the ground rod and the power system. They are usually made of copper.
  2. Grounding clamps are used to connect the electrode conductor to the rod.

The acorn clamp is an oval bolt clamp used to attach to a ground rod. It is a commonly used grounding rod clamp and is approved for use in direct disposal sites.

The brass barb clamp is a two-piece clamp with set screws, they are used to attach to the bar. It has a center point with a hole for attaching the wire and a set screw for tightening the wire. The clamp type is used to install the power system around water pipes.

Grounding and grounding has one purpose, which is to force electricity to be absorbed to the ground. This is done by connecting a ground wire to the electrode. There are several ways to do this:

Not everyone knows why grounding is needed. Without it, the risk of electric shock to residents of the house increases thousands of times. It is necessary to protect people and equipment from electric current.

Do-it-yourself grounding of a house with a contour involves the use of a structure made of metal blanks bursting into the ground at the same distance and closed with a corresponding strip. The PUE grounding diagram is shown in the image.

Before installing an energy system for a private house, it is necessary to clarify some important points.

  1. The best electrical conductivity is clay soil. This land is a great place to install a protective loop. Sandy soil can be treated with saline, it improves current conductivity, but reduces the life of the structure.
  2. A closed loop connected by a metal strip is safer than a straight one. In case of corrosion of one of the supports, the entire structure will continue to function.
  3. The place where the grounding is located is dangerous for people and animals! The outline should be enclosed or covered with decorative design elements.

A properly connected power system provides a grounding and bonding function as an integral protection system. The grounding of a private house plays an important role in the safety of residents.

Before grounding your home, check with the competent authority for electrical requirements or regulations in your area. If you need to build a turnkey house, contact the specialists.
