Gniazdko francuskie czy schuko – który typ wybrać?

Have you wondered why we find different standards for plugs and sockets in different countries? What type of socket you choose doesn't just depend on technical performance, but also has an impact on safety of use and compatibility with appliances. In today's article we will compare the two most common types of sockets used in Europe: French (type E) and schuko (type F).

Electrical sockets - what are they actually?

Electrical sockets, or more commonly known as contacts, are a key component of any electrical installation, allowing electrical appliances to be connected to a power source. Although they may look similar at first glance, sockets differ depending on the country in which they are used. In Poland, French sockets (type E) and schuko sockets (type F) are most commonly used; although they perform the same function, they differ in design and the way they are earthed.

French sockets, or E-type sockets

Type E sockets, also known as French sockets, are the most popular type of socket in Poland. They have two holes for the phase (L) and neutral (N) conductors, as well as a grounding pin, which is positioned above the holes.

Characteristics of E-type sockets:

  • Earthing: These sockets have a pin which is used to connect the earthing (PE) wire. Earthing is a key element to ensure safe use.
  • Load: French sockets are compatible with a current load of up to 16A.
  • Fitting plugs:
    • Type C (CEE 7/16 and CEE 7/17): The wide version (CEE 7/17) supports up to 16A, while the narrow version (CEE 7/16) supports up to 2.5A. Both versions fit ungrounded sockets.
    • Unischuko (type E/F): These are dual plugs that fit both French and German (schuko) sockets, having a pinhole and side plates.
  • Mismatched plugs: Plugs that do not have a grounding pin hole will not be compatible with a French socket.

E-type sockets are not only used in Poland, but also in the Czech Republic, Belgium, Slovakia and France.

Schuko sockets, or F-type sockets

F-type sockets, also known as schuko sockets, are the standard in many European countries, including Germany, the Netherlands and Croatia. They differ from French sockets mainly in the way the earthing is implemented.

Characteristics of F-type sockets:

  • Earthing: In F-type sockets, earthing is implemented by means of two spring-loaded plates placed on the sides of the socket. The earthing works similarly to type E, but does not use a pin.
  • Load: Like French sockets, schuko sockets work with loads up to 16A.
  • Symmetry: Schuko sockets are symmetrical, meaning that the plug can be turned 180° and the socket will function correctly.
  • Fitting plugs:
    • Type C (CEE 7/16 and CEE 7/17): As with French sockets, these plugs fit into ungrounded sockets.
    • Unischuko (type E/F): Dual plugs that fit both types of sockets (E and F), fitted with a pinhole and side plates.
  • Mismatched plugs: Plugs that do not have suitable recesses on the sides for the earthing plates will not fit schuko sockets.

Comparing French and schuko sockets - what to look out for?

The choice between a French and schuko socket depends mainly on local standards and the compatibility of electrical appliances. Here are some aspects to consider:

  • Compatibility with appliances: In most cases, modern appliances have unischuko (E/F) plugs, which fit both types of socket. However, older devices may require specific sockets.
  • Technical issues: E-type and F-type sockets have the same technical characteristics in terms of current load and safety. In practice, they differ mainly in the way earthing is implemented.
  • Usability: F-type sockets are more versatile as they allow the plug to be connected in any direction (180° inversion) without affecting performance. In contrast, French sockets (type E) with a grounding pin offer a secure connection so that the plug fits precisely into the socket, but do not have the same flexibility in installation as type F sockets.

How do you safely connect an electrical socket?

Whether you opt for an E or F type socket, it is important that the connection is made according to safety rules. Here are some key steps to follow:

  1. Switching off the current: Before starting any installation work, make sure that the current has been switched off on the circuit where you will be working. This can be checked using a voltage tester.
  2. Wiring connection: Standard sockets have three wires:
    • Brown/black (L) - phase wire.
    • Blue (N) - neutral wire.
    • Green/yellow (PE) - earth wire.
  3. Connection of wires to terminals: Connect the phase wire to the left terminal, the neutral wire to the right terminal and the earth wire to the terminal on the earth pin or plates (depending on the type of socket).
  4. Assembling the enclosure: Once the wires are connected, carefully fasten the socket enclosure, making sure that all components are tight and secure.
  5. Testing: Once the socket has been assembled, switch on the electricity and check for correct operation using a tester or connecting a simple device such as a lamp.

Choosing an electrical socket: French or schuko?

The choice of the right electrical socket - French or schuko - depends mainly on the country's standards and the needs of the user. Both types of socket have their advantages and disadvantages, but what they have in common is a high level of safety and compatibility with a wide range of appliances. Regardless of the choice, it is worth paying attention to professional installation to guarantee safe use of the electrical installation.

Interpower Connections: How to Design for France and Belgium

This month in Interpower Connections we are continuing our series on designing for export. We have discussed designing for Australia, Germany, the United Kingdom, and Denmark. France and Belgium use the CEE 7/VII plug, also known as the Continental European plug, which is used in Germany and many other European countries. The CEE 7/V socket is used in France and Belgium, along with other countries including Poland, the Czech Republic, and Slovakia. We will discuss the requirements and resources needed when designing for France and Belgium in this Interpower Connections article.The CEE 7/V socket is rated at 16 amps, 250 volts and has a male grounding pin on the face of the socket. In addition, France and Belgium require safety shuttering on all their sockets. The CEE 7/V socket is not compatible with the CEE 7/IV plug due to the male grounding pin. The CEE 7/VII plug can be used for the CEE 7/III and CEE 7/V sockets as it offers grounding clips on both sides to mate with the CEE 7/III socket and a female contact to accept the grounding pin on the CEE 7/V French/Belgian socket. The French/Belgian socket is not compatible with the CEE 7/IV plug which does not incorporate the female contact. See illustration below. The French/Belgian socket is pin polarized. It is notable that the CEE 7/VII plug is polarized when used in the French and Belgian electrical system. There are two types of polarization: physical and electrical. The illustration above demonstrates physical polarization, i.e. the ability to allow or stop a connection being made with the plug in one or more positions. Electrical polarization occurs when each line or connection of the supply is connected to a specific contact on the plug or socket, which is dictated by either a specific standard, or common practice. France and Belgium have no standard for wiring connectors; therefore, electrical polarization is non-existent.LCIE is the standards testing agency for France. When designing your product for export, you should contact the testing agency for the country you are designing for. Below is the link for France’s testing and approval agency.

When you have the appropriate standard numbers, you can purchase the standards. The standards contain the information you need to design your equipment and gain the appropriate approvals to export to France and Belgium.
