230V sockets: Everything you need to know


230V sockets are a basic element of the electrical infrastructure in most homes and buildings around the world. They are used to connect electrical devices to the power grid, enabling the use of electricity in everyday life. Regardless of whether we use a refrigerator, a computer or a bedside lamp, we always rely on these inconspicuous but extremely important devices. Below we present the most important information about 230V sockets, their types, rules of safe use and installation.

Types of 230V sockets

230V sockets come in various types to meet the various needs of users. Here are some of the most popular types:

  1. Single sockets: The simplest and most common type of socket, allowing you to connect one device. Perfect for home applications, such as connecting a night lamp or a phone charger.
  2. Double sockets: They allow you to connect two devices at the same time, which is especially useful in places where we need more power sources, for example in the kitchen, where you can connect an electric kettle and a mixer at the same time.
  3. Sockets with grounding: Equipped with an additional grounding cable, increasing safety of use. They are especially important in kitchens and bathrooms, where there is a risk of contact with water. Grounding protects against electric shock if the device is damaged.
  4. Sockets with switch: They have a built-in switch that allows you to cut off the power without having to remove the plug. They are convenient and help you save energy because you can easily unplug the device when not in use.
  5. Hermetic sockets: Provides protection against moisture and dust, ideal for outdoor use or in humid rooms such as garages or bathrooms. Thanks to this, we can safely use electrical devices in places exposed to difficult conditions.

Safety of use

Using 230V sockets requires following some basic safety rules to avoid the risk of electric shock or fire:

  1. Avoid overloading the sockets: Plugging too many devices into one socket can overload the socket and pose a fire hazard. Use splitters sparingly and pay attention to the maximum load on the socket.
  2. Check the condition of the sockets regularly: Damaged sockets may result in electric shock. If you notice any damage such as cracks, loose connections or burnt holes, replace the socket immediately.
  3. Use grounded sockets: In areas exposed to water, such as kitchens and bathrooms, always use grounded sockets to increase safety and protect against electric shock.
  4. Do not handle sockets wet: Never touch sockets with wet hands to avoid the risk of electric shock. If necessary, use sockets in wet conditions, with dry hands or with dry tools.

Installation of 230V sockets

The installation of sockets should be performed by a qualified electrician to ensure correct installation and safe use. Nevertheless, it is worth knowing the general assembly steps to better understand the process:

  1. Power off: Always turn off the power at the fuse box before starting electrical work. This is the most important step to ensure your safety while working.
  2. Preparation of the installation site: Select a suitable place on the wall where the socket will be mounted. Make sure it is a dry and safe place with easy access to electrical wiring.
  3. Connecting the cables: Connect the wires to the appropriate terminals in the socket (L – phase, N – neutral, PE – earth). Accurate connection is crucial for the proper functioning of the socket and the safety of users.
  4. Socket installation: Fix the socket in the prepared place and make sure it is firmly attached. Check that all connections are secure and that the socket is not loose.
  5. Testing: After installing the socket, turn on the power and test the socket operation with a voltage tester. Make sure the socket is working properly and there are no power issues.


230V sockets are an integral part of every electrical installation, enabling safe and convenient use of electrical devices. Remember to choose the right type of socket for your needs, follow safety rules and commission the installation to qualified specialists. Thanks to this, you and your family will be able to safely use electricity every day. Correctly selected and installed sockets guarantee safety and comfort of use, which is extremely important in every home and workplace.
