What type of plugs and sockets are used in Poland?

In Poland, plug and socket types C and E are the official standards. Unlike almost all other European countries, Poland and its neighbouring countries the Czech Republic and Slovakia have standardized on the French plug and socket system. Fortunately, this does not pose a problem since the French standard is fully compatible with the German type F system, which is used in the rest of Continental Europe.

Type C

  • commonly used in Europe, South America & Asia
  • 2 pins
  • not grounded
  • 2.5 A, 10 A & 16 A
  • almost always 220 – 240 V
  • socket compatible with plug type C

What is the mains voltage in Poland?

Just like the rest of Europe, the voltage in Poland is 230 volts and the frequency is 50 Hz.

Background information

Type C Bakelite wall socket (1950s)

Poland has standardized on type E sockets and plugs. Type C and type F plugs can also be used thanks to their compatibility with type E sockets. However, it is not permitted to install type C wall outlets anymore. But why is that?

Power plug & outlet Type C

Typically, type C plug sockets are not allowed to be installed in Poland: these outlets are not earthed and are therefore considered dangerous. Only type E power points are permitted because they are grounded and therefore significantly safer.

The only (and rare) exception to this rule, is that an old type C outlet should be replaced by a new one. After all, if you hook up a grounded wall outlet (i.e. type E) on a two-wire circuit, the socket will not be grounded, but people will get the impression that it actually is grounded. No need to say, this is a potentially dangerous situation.

Nowadays, however, type C receptacles are not frequently installed anymore, since older properties are almost always completely rewired when they are renovated or significantly altered.

Power plug & outlet Type E

Obsolete type E plug, i.e. without top and bottom earthing clips nor plastic notches on the left and right.

In the past, type E plugs and sockets were incompatible with type F. The reason for the initial incompatibility was that grounding in the type E socket is accomplished with a round male pin, which is permanently mounted in the socket.

Old type F plugs did not have a grounding hole to accept the earth pin of the type E socket. Old type E plugs, on the other hand, did not have top and bottom indentations with earthing clips to mate with the type F socket. Moreover, old type E plugs were perfectly round and lacked a necessary pair of plastic notches on the left and right side to fit the type F socket. Fortunately, the now standard hybrid E/F plug (officially called CEE 7/7) was developed in order to bridge the differences between E and F sockets.
