Type I is mainly used in Australia, New Zealand, Papua New Guinea, China and Argentina. This 10 amp plug has two flat 1.6 mm thick blades, set at 30° to the vertical, forming an upside-down V. Their centres are spaced 13.7 mm apart and both prongs measure 17.3 mm in length and 6.3 mm in width. The flat earth blade also measures 6.3 by 1.6 mm, but it is 20 mm long. The distance between the centre of the grounding pin and the middle of the plug is 10.3 mm. There is an ungrounded version of this plug as well, with only two flat V-shaped prongs. Both plug versions have insulated live and neutral pins, so even if the plug is not fully inserted into a socket, touching the exposed part of the prongs can’t give you a shock. A plug/socket configuration rated at 15 amps is also available, but the ground pin is wider: 8 mm instead of 6.3 mm. A standard 10 amp plug will fit into a 15 amp outlet, but a 15 amp plug only fits this special 15 amp socket. There is also a 20 amp plug whose prongs are wider still. A lower-amperage plug will always fit into a higher-amperage outlet but not vice versa. Australia’s plug/socket system is codified as standard AS 3112. Although there are slight differences (the pins of Chinese plugs are 1 mm longer and the sockets are installed with the earth contact facing upwards), the Australian plug mates with the socket used in the People’s Republic of China (mainland China). The reason as to why the dimensions of the Australian type I are very similar to those of type A is because the Australasian standard is actually an obsolete type of American plug. It was patented in 1916 by Harvey Hubbell II, the same electrical engineer who had invented the type A plug. Hubbell’s three-blade design never proved popular in the U.S. because of its incompatibility with the existing type A plug, but it was favoured in Australia over the British type D system, because it was easier for local manufacturers to make plugs with flat pins rather than round ones. In the 1930s, the predominant Australian electrical accessory manufacturers, along with the State Electricity Commission of Victoria, decided to standardize on Hubbell’s design.

Type N is used almost exclusively in Brazil. The type N socket and plug are the official standard in Brazil. The plug consists of two pins and a grounding pin. There are two variants: the prongs of the 10 A version have a diameter of 4 mm and a length of 19 mm. The second version, rated at 20 amps, is used for heavier appliances and has 4.8 mm round pins, but also measuring 19 mm in length. The centres of the line and neutral pins are spaced 19 mm apart. The centre-to-centre distance between the earth pin and the middle of the imaginary line connecting the two power pins is 3 mm.

Type E is primarily used in France, Belgium, Poland, Slovakia, the Czech Republic, Tunisia and Morocco. France, Belgium and some other countries have standardized on a socket which is different from the CEE 7/4 socket (type F) that is standard in Germany and other continental European countries. The reason for incompatibility is that grounding in the E socket is accomplished with a round male pin, which is permanently mounted in the socket. This earth pin is 14 mm long and has a diameter of 4.8 mm.  The plug itself is similar to C except that it is round and has the addition of a female contact to accept the socket’s grounding pin. The plug has two 4.8 mm round pins, measuring 19 mm in length on centres spaced 19 mm apart. The centre-to-centre distance between the female contact and the middle of the imaginary line connecting the two power pins is 10 mm. In order to bridge the differences between sockets E and F, the CEE 7/7 plug was developed (see photo on the left): it has grounding clips on both sides to mate with the type F socket and a female contact to accept the grounding pin of the type E socket. The original type E plug, which does not have grounding clips, is no longer used, although very rarely it can still be found on some older appliances. Note that the CEE 7/7 plug is polarised when used with a type E outlet. The plug is rated at 16 amps. Above that, equipment must either be wired permanently to the mains or connected via another higher power connector such as the IEC 60309 system. A type C plug fits perfectly into a type E socket. The socket is recessed by 15 mm, so partially inserted plugs do not present a shock hazard. 10~16A/250V 4.8 mm, 4.8 mm prongs Insulated Voltage - Proof: 3KV CE Approved RoHS compliant Note: Plug adapters do not convert voltage, they just change the plug type. Use a proper voltage converter along with a plug adapter if your device is incompatible with the country's voltage.

Type C is used in all countries of Europe except the United Kingdom, Ireland, Cyprus and Malta. Type C is probably the single most widely used international plug. This two-wire plug is ungrounded and has two round prongs. It is popularly known as the Europlug which is described in CEE 7/16. The plug has two 4 mm round pins, measuring 19 mm in length on centres spaced 18.6 mm apart at the base and 17.5 mm apart at the tip. The two pins have 10 mm long insulated sleeves. They converge slightly, but they are relatively flexible which allows the plug to mate with any socket that accepts 4.0 – 4.8 mm round contacts on 17.5 – 19 mm centres. The plug is generally limited for use in class II applications that require 2.5 amps or less. It is, of course, unpolarised. It is commonly used in all countries of Europe except in the United Kingdom, Ireland, Cyprus and Malta. It is also used in various parts of the developing world. Whereas type C plugs are very commonly used, this is not the case for type C sockets. This kind of socket is the older and ungrounded variant of socket types E, F, J, K or N. Nowadays most countries demand grounded sockets to be installed in new buildings. Since type C sockets are ungrounded, they have become illegal almost everywhere and they are being replaced by types E, F, J, K or N (depending on the country). So as to leave no doubt: only the sockets have become illegal, the plugs remain in use of course. A type C plug fits perfectly into a types E, F, J, K or N socket. This product is a passive device and does not convert voltage. Any item plugged in must already be compatible with the voltage being supplied by the socket.

Type D is used almost exclusively in India and Nepal. India has standardized on a plug which was originally defined in British Standard 546 (the standard in Great Britain before 1947). This 5 amp plug has three round prongs that form a triangle. The central earth pin is 20.6 mm long and has a diameter of 7.1 mm. The 5.1 mm line and neutral pins are 14.9 mm long, on centres spaced 19.1 mm apart. The centre-to-centre distance between the grounding pin and the middle of the imaginary line connecting the two power pins is 22.2 mm. Type M, which has larger pins and is rated at 15 amps, is used alongside type D for larger appliances in India, Sri Lanka, Nepal and Pakistan. Some sockets can take both type M and type D plugs. 10A/250V 7.0 mm, 5.0 mm, 5.0 mm Prongs Insulated Voltage - Proof: 3KV CE Approved RoHS Compliant Note: Plug adapters do not convert voltage, they just change the plug type. Use a proper voltage converter along with a plug adapter if your device is incompatible with the country's voltage.

Type H is used exclusively in Israel and Palestine. This earthed 16 amp plug is unique to Israel. It has three 4.5 mm round prongs, measuring 19 mm in length and forming a triangle. The centres of the line and neutral pins are spaced 19 mm apart. The centre-to-centre distance between the earth pin and the middle of the imaginary line connecting the two power pins is 9.5 mm. 10A/250V 4.0 mm, 4.0 mm, 4.0 mm Prongs (Round) Insulated Voltage - Proof: 3KV CE Approved RoHS Compliant Note: Plug adapters do not convert voltage, they just change the plug type. Use a proper voltage converter along with a plug adapter if your device is incompatible with the country's voltage.

Type L is used almost exclusively in Italy, Chile and is also randomly found throughout North Africa. The Italian grounded plug/socket standard, CEI 23-16/VII, includes two styles rated at 10 and 16 amps. Both plug top styles consist of three rounded pins placed in a straight line. They differ in terms of contact diameter and spacing, and are therefore incompatible with each other. The 10 amp version has three 4 mm round pins, measuring 19 mm in length. The centres of the line and neutral pins are spaced 19 mm apart. 10A/250V 4.0 mm, 4.0 mm, 4.0 mm Prongs For Recessed and non-Recessed outlets Insulated Voltage - Proof: 3KV CE Approved RoHS Compliant Other countries include: Chile, Ethiopia, Italy, Lybia, Syria, Tunisia, Uruguay Note: Plug adapters do not convert voltage, they just change the plug type. Use a proper voltage converter along with a plug adapter if your device is incompatible with the country's voltage.

Type M is used almost exclusively in South Africa, Swaziland and Lesotho. The central earth pin is 28.6 mm long and has a diameter of 8.7 mm. The 7.1 mm line and neutral pins are 18.6 mm long, on centres spaced 25.4 mm apart. The centre-to-centre distance between the grounding pin and the middle of the imaginary line connecting the two power pins is 28.6 mm. 10A/250V 7.0 mm, 5.0 mm, 5.0 mm Prongs Insulated Voltage - Proof: 3KV CE Approved RoHS Compliant Other countries include: Botswana, Lesotho, Mozambique, South Africa, Swaziland Note: Plug adapters do not convert voltage, they just change the plug type. Use a proper voltage converter along with a plug adapter if your device is incompatible with the country's voltage.

Type J is used almost exclusively in Switzerland and Liechtenstein. Switzerland has its own standard which is described in SEC 1011. This plug is similar to C, except that it has the addition of a grounding pin. Type J plugs have three 4 mm round pins, measuring 19 mm in length. The centres of the line and neutral prongs are spaced 19 mm apart and they have 10 mm long insulated sleeves. 10A/250V 4.0 mm, 4.0 mm, 4.0 mm Prongs For Recessed and non-Recessed outlets Insulated Voltage - Proof: 3KV CE Approved RoHS Compliant Note: Plug adapters do not convert voltage, they just change the plug type.

Type G is mainly used in the United Kingdom, Ireland, Cyprus, Malta, Malaysia, Singapore and Hong Kong. This 13 amp plug has three rectangular prongs that form an isosceles triangle. The central earth pin is 4 by 8 mm and 22.7 mm long. Line and neutral pins are 4 by 6.35 mm and 17.7 mm long, on centres spaced 22.2 mm apart. The centre-to-centre distance between the earth pin and the middle of the imaginary line connecting the two power pins is 22.2 mm. The 9-mm long insulated sleeves prevent accidental contact with a bare connector while the plug is partially inserted. British Standard BS 1363 requires use of a three-wire grounded and fused plug for all connections to the power mains. Two-wire class II appliances are not earthed and often have a plastic grounding pin which only serves to open the shutters of the outlet. The lack of such an earth pin on a type C plug makes it impossible to connect it to a type G receptacle, although it can actually be forced into the socket by sticking a pointy (dry, non-metallic !) object into the centre hole of the power outlet, which opens up the two other holes. Just to be perfectly clear, this is not a piece of advice; it’s simply an observation! In the UK, the power sockets in a house are connected by means of ring circuits, which are protected by 32 A circuit breakers. This type of wiring is rarely used outside the UK and requires the use of fused plugs. Small appliances, like mobile phone chargers, usually have a 3 A cartridge fuse inside the plug; heavy duty appliances, such as coffee makers, have a plug with a 13 amp cartridge fuse. Almost everywhere else in the world radial circuits are used. In this system each wall socket, or group of sockets, has a circuit breaker at the main switchboard, so there is no need for plugs to be fused. As a result, if you take some foreign appliance to the UK, you can use an adaptor, but technically it must incorporate the correct value fuse. Most would have a 13 amps one, too big for computers for example. Type G plugs and sockets started appearing in 1946 and the standard was first published in 1947. By the end of the 1950s, it had replaced the earlier type D outlets and plugs (BS 546) in new installations in the UK, and by the end of the 1960s, most earlier installations had been rewired to the new standard. Type G wall sockets almost always include switches for extra safety. UK plugs are no doubt among the safest in the world, but also among the most hulking and cumbersome. That’s why people often make fun of them saying that a British plug is mostly bigger than the appliance it is connected to… Moreover, the bottom-heavy design of the plug makes it a perfect caltrop.

Type A is used, for instance, in North and Central America and Japan. This class II ungrounded plug with two flat parallel prongs is pretty much standard in most of North and Central America. It is known as NEMA 1-15 and was invented in 1904 by Harvey Hubbell II. The plug has two flat 1.5 mm thick blades, measuring 15.9 – 18.3 mm in length and spaced 12.7 mm apart. Type A plugs are generally polarised and can only be inserted one way because the two blades do not have the same width. The blade connected to neutral is 7.9 mm wide and the hot blade is 6.3 mm wide. This plug is rated at 15 A. Type A and B plugs have two flat prongs with a hole near the tip. These holes aren’t there without a reason. If you were to take apart a type A or B socket and look at the contact wipers that the prongs slide into, you would find that in some cases they have have bumps on them. These bumps fit into the holes so that the outlet can grip the plug’s prongs more firmly. This prevents the plug from slipping out of the socket due to the weight of the plug and cord. It also improves the contact between the plug and the outlet. Some sockets, however, do not have those bumps but just two spring-action blades that grip the sides of the plug pin, in which case the holes are not necessary. There are also some special outlets which allow you to lock the cord into the socket, by putting rods through the holes. In this way, vending machines and the like cannot be unplugged. Moreover, electrical devices can be factory-sealed by the manufacturer using a plastic tie or a small padlock through one or both of the plug prong holes. For example, a manufacturer might apply a plastic band through the hole and attach it to a tag that says: “You must do X or Y before plugging in this device”. The user cannot plug in the device without removing the tag, so the user is sure to see the tag. Type A and B plugs are not insulated (i.e. the pin shanks do not have a black covering towards the plug body like type C, G, I, L or N plugs) and the outlets are not recessed into the wall, which means that if a the plug is pulled halfway out, its prongs are still connected to the socket. Type A and B sockets are potentially dangerous, since the distance between the receptacle and a partially pulled-out plug is big enough to touch the pins with your fingers or with a metal object such as a teaspoon. This product is a passive device and does not convert voltage. Any item plugged in must already be compatible with the voltage being supplied by the socket.
