Why do European plugs have 2 pins? The problem of an electric shock became a hazard for users because of the predominance of more powerful devices in the 1930s. The earth connection had to be fitted to the plugs for the devices.
Why are there two pins in a plug?
Two pins is more safe than one pin. And it makes the design symmetric, so it can be connected in any orientation. Show activity on this post. Your claim is not true. EU socket/plug standard is a combination of almost all older standards in the EU. It was design that german DIN standard plugs are somewhat compatible with italian or french ones.
What type of power plug is used in Europe?
In most European countries the classic power plugs and sockets of type C and F are generally used, both with two round plugs. While in France, Belgium, the Czech Republic, Slovakia and Poland power plugs and sockets of type C and E are used instead, both with two round pins.
Why do European plug sockets have one pin for Earth?
Not all European AC plugs/sockets are the Schuko's you show. Many have a single pin for earth, or indeed none at all. I imagine that it's a design feature to ensure reliable earth connection without using a huge pin as in the UK !
Which sockets are used in Europe?
But in almost all European countries – with the exception of the English islands (United Kingdom and Ireland) and the islands of Malta and Cyprus – the type C socket with two round pins is universally used. In most European countries the classic power plugs and sockets of type C and F are generally used, both with two round plugs.

Why do some countries have 2 pin plugs?
As previously mentioned above, due to the predominance of more powerful devices in the 1930s, (normally above around 500 watts), the problem of a possible electric shock became a hazard for users. In order to provide safety, an earth connection had to be fitted to 2-pole plugs for these devices.
Which countries use 2 pin plugs?
Very similar to type E but with two grounding clips = two clips that are inserted into the two pins of the wall plug. This is used in: there is still a residual presence in many countries of Europe, including Spain, and in Jordan, South Korea, Indonesia, Thailand, Turkey, Uruguay and Vietnam.
Are 2 pin plugs safe?
Why are Two-Prong Outlets Considered Dangerous? The main reason two-prong outlets are considered outdated and dangerous is due to their lack of grounding. Grounding is how electricity is safely transferred in the case of an unstable current.
Can 2 prong US plugs go into EU sockets?
Definitions for Electrical Conversion Devices Plug Adapter: an interface that attaches between the American two-pronged plug and a specific European socket. The result is that the American appliance will be connected to European 220v 50 cycle electrical power.
Why are European plugs so big?
The reason plugs in the UK are so big is that each one must be individually fused. And the reason for that is something called a "ring circuit". In a ring circuit you have, say, a 40 amp fuse at the mains/box. From this you send out two wires, each rated only for 20 amps, going in a circle around the house.
Will a 2 pin plug work in Italy?
The good news is that both three-pin sockets will allow two-pin plugs to be inserted into them, which in turn means that a two-pin Italian C plug will work in any of the three potential socket types. Repeat: a 2-pin Italian C plug will fit all Italian sockets.
Are two pin plugs legal in UK?
The first aspect to recognise is that UK power outlets have a three-pin format for their connectors, while European countries adopt a two-pin format. Unless the appliance from Europe has a minimal amp rating (such as that found on an electric shaver or toothbrush), it's not advisable to use a standard two-pin adapter.
What is the advantage of a 3 pin plug over a 2 pin plug?
In comparison to a 2-pin connector, 3-pin plugs limit the amount of power that may pass through the circuit. As a result, 3-pin plugs are safer than 2-pin plugs. Reason for how three pin plugs will ensure the safety: A three-pin plug's pin E makes contact with the earth line.
Is it safe to plug a 2-prong into a 3-prong outlet?
Yes, rather than using an unsafe adapter, we would recommend you upgrade your electrical socket from two-prong to three-prongs. Even though the adapter enables modern appliances to work with outdated outlets, they are to be considered a temporary solution – not suitable for the long term.
Why are European plugs different?
Companies in Europe realized that supplying power at 220 volts instead of 110 volts would be cheaper. At a higher voltage, electric companies can deliver the same power with less current – picture a narrow stream flowing quickly compared to a wider stream flowing slowly. And less current allows for thinner wires.
What's the difference between us plug and EU plug?
The standard in North America is 110 to 120 volts, while the European standard is 220-240 volts. This necessitates a difference in the way outlets are constructed in Europe and in North America.
Are UK plugs safer than European?
The fuse and sturdy construction prove the British plug is very clearly the safest in the world. But it's better than that, because the sockets also feature shutters that prevent children from inserting paperclips and getting a nasty shock.
Why 3 pin plug is safer than 2 pin plug?
In comparison to a 2-pin connector, 3-pin connectors safeguard our safety from current. In comparison to a 2-pin connector, 3-pin plugs limit the amount of power that may pass through the circuit. As a result, 3-pin plugs are safer than 2-pin plugs.
What plug is used in China?
For China there are three associated plug types, types A, C and I. Plug type A is the plug which has two flat parallel pins, plug type C is the plug which has two round pins and plug type I is the plug which has three flat pins in a triangular pattern. China operates on a 220V supply voltage and 50Hz.
What plug does Korea use?
For South Korea the associated plug type is F, which is the plug that has two round pins with two earth clips on the side. South Korea operates on a 220V supply voltage and 60Hz.

Why do European electric outlets not have a ground? - Quora
Answer (1 of 6): They do. The UK the pin plug Earth is the one bigger longer prong and on the continental two prong the Earth is the long silver strip set into the outer edge.
Why does Germany have 2-pin power sockets? Would there not be ... - Quora
Answer (1 of 6): If you're talking about the German Type F (CEE 7/4) Schuko plug then it actually comes with earth 'clips' at the top & bottom. See this plug in the picture below as well as the corresponding socket. The plug above when plugged into it's corresponding socket will have the earth ...
Differences in USA and European AC Panels - Blue Sea Systems
SAFETY GROUND: The USA 120 V (60Hz) supply typically has three wires, 1-hot, 1 neutral, and 1-safety ground. 120V (60Hz) is obtained between the hot and neutral leads.
Why do french plug sockets have no earth??? - Angloinfo Brittany
The "why?" is actually quite straightforward. Until relatively recently, few French houses contained the sort of electical appliances that required earthing (except for a couple in the kitchen), and the power supply typically supplied by EDF lacked the grunt to make them work, anyway, so the houses were wired for low-draw appliances such as lamps (which consolidated a situation in which few ...

Who invented the two prong plug?
In the early 1900s, inventor Harvey Hubbell improved on the idea with his Separable Attachment Plug. The plug had an inner connector screwed into the light socket and an outer connector (attached to an appliance by a cord) that plugged into that via two prongs and could easily be popped in and out. It was the ancestor of the modern two-prong plug and socket.
Why do plugs and sockets differ from region to region and even country to country?
In a nutshell, plugs and sockets differ from region to region and even country to country because, at the time they were being developed, no one really saw any reason to make them all the same. First, a little history. When electricity was first introduced into homes and businesses, it was primarily for powering lights.
When did the N plug come out?
In 1986 , the International Electrotechnical Commission unveiled a “universal plug,” known as a Type N plug, that they hoped would become a widespread standard. So far, though, only Brazil and South Africa have adopted the design for their plugs and wall outlets.
How many grounding pins does a plug have?
Inside a plug there is one grounding wire, while the socket has two grounding pins. I know that the wire splits into two, but why? As the wiring inside the wall is supposed to be the same between different types, I assume it is just a design decision, however does this mean that in such design I could theoretically have one broken pin for grounding and successfully ground a plugged device only by using one pin on the socket?
What does dual earth pins do?
If you are referring to these sockets the dual earth pins give balance pressure on the plug which would otherwise be forced to upwards or downwards making insertion difficult and possibly affecting the contact of the L and N pins in their sockets.
Why were the Czech sockets changed?
The standards were changed to gain the compatibility. The sockets in Czech Republic, which followed the french standard, are round (no notches) with the groun pin; the plugs are notched body (to fit in german socket) wit both hole for ground pin and notches for the german ground connectors. The universal EU socket would look like this:
What is the Italian standard for ground connectors?
Italian standard, on the other hand, use anther approach to the symmetry - one central ground connector in between hot and neutral. The outer shape is flat hexagonal and is same as "other" european 2-wire 230 VAC connectors.
Do all European AC plugs have Schuko?
