The IEC provide the definitive guide to which plugs and sockets are used in every country of the World. For Europe and Scandinavia, the map below provides at least a simplistic view:
The most common socket in Europe is the Schuko (Schutzkontakt is German for &#;Protective contact&#;). The plug has two pins, and along with the socket can be identified by the two metal earth contacts on each side (labelled green in the picture above). The plug is rated at 230v 16A, and has two 4.8mm x 19mm pins.
Unlike UK plugs and sockets, they can be connected either way around, and there is no convention as to whether sockets have the live wired to the left or right receptacle (a receptacle is the hole in a socket which a plug pin fits into). For applications where it is crucial that the live/neutral are connected the correct way, you can easily use our socket tester to show which way the socket is wired (polarity). If it is correct, happy days - if not, simply pull out the plug and turn it 180 degrees.
The second most common socket in Europe is the French type, which like the Schuko is rated at 230v 16A, and has two 4.8mm x 19mm pins. Whilst it looks very similar to the Schuko design, there is one major difference. The earth connection is made by an earth pin which protrudes from the socket, and engages with a hole in the plug (there are no side earth strips).
The protruding earth pin means that the plug can only be inserted one way around, just like UK plugs. The major issue is that until , there was no convention as to whether sockets had the live wired to the left or right receptacle. However, it is now more likely that the live will be wired to the right (as you face the socket). This cannot however be relied upon, as many sockets are still wired the other way, and to further confuse matters, the Czech standard still recommends wiring the live to the left!
You therefore have a 50:50 chance of it being wired the correct way and unlike with the Schuko socket, you cannot rotate the plug 180 degrees to solve the issue.
In order to bridge the differences between German and French standards, the CEE 7/7 plug was developed. It has a hole to accept the earth pin on a French socket, and side strips to connect to the earth clips on the side of German Schuko sockets. It is often incorrectly referred to as a Schuko plug. All Tough Leads European leads and adaptors use this universal plug.
Italian (Type L)
Traditional Italian Socket
New Bipasso Socket
10A 16A
Historically Italy has had its own specific socket, available in 10A and 16A versions. If the plug does not have the rating on, you can determine the type by measuring the distance between the two outer pins. Many sockets (as pictured top) will accept both 10A and 16A plugs. It can be inserted either way around, so reverse polarity can be corrected by turning the plug 180 degrees.
Many buildings now have the Bipasso/Schuko socket, which can be used with both Italian and Schuko plugs. The universal CEE 7/7 European plug will work in Italy where the Bipasso/Schuko socket is available, otherwise a 10A or 16A Italian plug adaptor is required. Both Italian and Schuko plugs can be inserted either way around in the Bipasso/Schuko socket, so reverse polarity can be corrected by turning the plug 180 degrees.
Switzerland (Type J, SN)
10A 16A
Switzerland and Liechtenstein use their own specific socket, available in 10A (round pins) and 16A (square pins) versions. As the central earth pin is offset, it can only be inserted one way around. There is a convention to wiring the live, so reverse polarity should not be an issue. 10A plugs can be inserted into 16A sockets, but the reverse is not possible.
Denmark (Type K, DS-2-D1)
Denmark and Greenland use their own 16A socket. As the central earth pin is offset, it can only be inserted one way around. There is a convention to wiring the live, so reverse polarity should not be an issue.
Whilst the socket looks similar to a Schuko/French socket, they must not be used together. Although they will fit, the earth will not be connected, which is extremely hazardous.
From French sockets were allowed to be fitted in Denmark, with Schuko sockets supported from . Data on their prevalence is not available and so it is likely that in many places a Danish adaptor will still be required.
The 230v 5A/6A round pin plug is based on the original British BS546 design, which is still used in the UK for table lamps. It is easy to confuse with the larger 15A variant (type M). If in any doubt, measure the distance between the bottom two pins, which will be 19mm.
The 230v 15A/16A round pin plug is based on the original British BS546 design which is still used in the UK for stage lighting. It is easy to confuse with the smaller 5A variant (type D). If in any doubt, measure the distance between the bottom two pins, which will be 25.2mm.
Used exclusively in Israel and the West Bank. Rated at 230v 16A it has three 4.5mm round pins, 19 mm in length. Whilst Schuko and French plugs can sometimes be forced (the pins are 0.3mm too larger in diameter) into this an Israel socket, the earth will not be connected, which is extremely hazardous.
The 10A version is the most common plug in Australia and New Zealand, with 3 pins in a triangle set at 30 degrees to the vertical. A 2 pin version also used for double insulated appliances and fits in the 3 receptacle socket. Larger appliances may use a larger 15A type, which is not cross-compatible with the 10A socket.
Industrial IEC (Commando) Connectors
In the s the body now known as the International Electrotechnical Commission (IEC) published a worldwide standard for industrial connectors, which was adopted by the UK in . The standard, which is referred to today as IEC , resulted in widespread standardisation. They are often referred to in the UK as 'Commando connectors' after the MK range.
Each current rating of plug is a different diameter, with the pins keyed to ensure that only compatible plugs will fit a socket. Only 16A and 32A versions are shown below, with connectors also available in 63A and 125A. The standard colour code shows the voltage, with yellow for 100-130v, blue 200-250v and red 380-480v.
230v 16A Blue Sockets
Commonly used at campsites and marinas across Europe and the UK. Three pins, single phase, plug diameter 43mm.
230v 32A Blue Sockets
Three pins, single phase, plug diameter 57mm.
415v 16A Red Sockets
Five pins (3P+N+E), three phase, plug diameter 56mm. All Tough Leads 3 phase connectors are 5 pin as standard.
Sometimes the less common four pin (3P+E) version is used. Four pin sockets cannot be used for appliances which require a neutral.
415v 32A Red Sockets
Five pins (3P+N+E), three phase, plug diameter 63mm. All Tough Leads 3 phase connectors are 5 pin as standard.
Sometimes the less common four pin (3P+E) version is used. Four pin sockets cannot be used for appliances which require a neutral.
Many appliances require an earth connection to operate safely. An earth connection ensures that if there is a fault and an external metal part becomes live, the earth wire safely conducts the electricity away, tripping the circuit breaker or blowing the fuse. For example, imagine using a metal power tool. If an earth connection is present, then if there were to be a fault and the metal case of the tool became live, electricity would flow down the earth wire, quickly cutting off the power. If there was no earth connection, the tool would remain live. If you were to touch it, electricity would flow through your body to the ground, with potentially fatal consequences unless an RCD was fitted.
With any metal/class 1 appliance, you must always ensure that the adaptor you use connects the earth pin. It is therefore best to use adaptors with a universal plug connection (an earth hole and metal side strips), as they will work with both French and German types of socket. It is possible to insert a French plug into a German socket, and for a German plug to fit into a French socket- the appliance will work, but there will be no earth connection.
You must also never assume that just because a socket has an earth connection, that it is actually wired to earth. The only way to find out is to use a socket tester (see polarity section).
Some appliances do not require an earth connection. They are known as type 2 and will have a symbol of a square inside a slightly larger square on the appliance label. Other clues (although not 100% reliable), are a plastic case or flat 2 core cable.
The UK electrical system is polarised. The earth pin on 13A plugs is at the top, they can only be inserted one way and the live is always wired to the right hole (as you face a socket). As the live is always connected one way, appliances are wired with this in mind. For example, a switch may only turn on/off the live wire. If the appliance is used in Europe and the polarity is reversed (e.g. the live is connected to neutral, and neutral to live) such as would occur when using a Schuko socket which can be inserted either way round, the switch now only turns on/off the neutral. The appliance would appear off, but it is actually still live.
This is particularly important when connecting caravans and motor homes, as they will often have circuit breakers that isolate only the live. If the polarity is reversed and a fault occurs, they will cut off the neutral. This leaves the faulty appliance still live, which could prove fatal, particularly if there was also an earth fault e.g. the metal of a caravan would remain live and electrocute anyone who touched it. Use a polarity reversal adaptor to overcome the issue.
Always use a socket tester to check a socket before using it to ensure that it has the correct polarity, and the earth is connected.

What is the Difference Between Schuko Plug Socket and Normal Socket?
Have you ever wondered why electrical sockets differ so much across countries? Or why some devices fit seamlessly in European outlets but require an adapter elsewhere? The answer lies in the differences between a Schuko plug socket and a normal socket.
In this guide, we&#;ll break down the unique features of Schuko power sockets. We&#;ll also compare these to regular sockets, which are common in non-European regions.
By the end of this article, you&#;ll know exactly which type suits your needs.

Schuko Plug Socket: An OverviewThe term &#;Schuko&#; originates from the German word &#;Schutzkontakt&#;, meaning &#;protective contact.&#; This design prioritizes electrical safety and is common in many European countries. The Schuko socket follows the CEE 7/3 standard. On the other hand, the corresponding plug adheres to the CEE 7/4 standard. Both components integrate essential safety features such as grounding and surge protection.
Features of Schuko Plug Sockets
A standout feature of the Schuko electrical plug is its grounding pin. It provides additional protection against electrical shocks.
Schuko sockets are symmetrical, allowing plugs to be inserted either way, making them versatile.
These sockets support higher currents (up to 16 amps), ideal for heavy-duty appliances.
Many Schuko sockets include safety shutters. These prevent children from inserting objects.
These plugs are often flush-mounted and made from duroplastic material. The feature leads to durability and heat resistance.
Some Schuko power sockets feature built-in surge voltage protection. It guards devices against sudden power spikes.
Regular Socket: A ComparisonA regular socket refers to standard power outlets commonly found outside Europe. It is also common in regions where grounding systems differ.
Unlike Schuko sockets, regular sockets are usually polarized and lack advanced grounding mechanisms. While simpler in design, they don&#;t offer the same level of electrical safety.
Key Differences at a Glance

The protective earth contact ensures safety by redirecting fault currents away from users. This prevents incidents of electric shocks.
The grounding is achieved via two metal clips on the socket&#;s side. It engages with matching contacts on the plug.
Regular SocketsIn contrast, grounding mechanisms in regular sockets vary significantly depending on the country or region. For example:
Schuko sockets are non-polarized. What this means is that the plug can be inserted either way without affecting its functionality. This design ensures flexibility in connecting devices while maintaining the same level of safety.
Regular SocketsMost regular sockets, such as those in North America (Type A and Type B), are polarized. This means they have a designated &#;live&#; and &#;neutral&#; side to ensure consistent electrical flow. While this can be beneficial for some devices, it reduces flexibility.
Current Capacity Schuko SocketsSchuko sockets are designed to handle a maximum current of 16 A. This makes them suitable for high-power appliances such as heaters, washing machines, or industrial equipment.
Regular SocketsRegular sockets typically have lower current ratings. For example, U.S. sockets are generally rated at 15 A. This limits their compatibility with high-demand appliances without additional infrastructure.
Safety Features Schuko SocketsSafety is at the heart of Schuko socket design:
While some regular sockets now include advanced features like tamper-resistant designs, these are not universal. Surge protection often requires external devices such as surge protectors. Thus, it may add to the socket&#;s cost and complexity.
Mounting and Durability Schuko SocketsSchuko systems are typically flush-mounted. This feature gives Schuko sockets a neat and modern look. The use of durable materials like duroplastic ensures longevity. It also enhances the socket&#;s resistance to wear, heat, and mechanical damage.
Regular SocketsThe mounting style and material quality of regular sockets vary widely. Some of them are surface-mounted or using less durable plastic.
Compatibility Schuko SocketsSchuko sockets are highly versatile. They can accommodate a wide range of plug types adhering to European plug standards. They can accept both:
Regular sockets are less versatile, as their designs are region-specific. A Type A plug, for example, cannot be used in a Type B socket without an adapter.
Where Are Schuko Plug Sockets Used?Schuko sockets are prevalent in most European countries, including Germany, Austria, Poland, and France. For example, in response to the question, &#;What plugs do they use in Poland?&#;, the answer is primarily Schuko sockets due to their compatibility with Polish electrical sockets.
