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.
Why are British and European plugs different?
To save copper, Britain adopted the ring main system, with sockets connected sequentially, but this meant each connection needed its own fuse. Instead of putting the fuses in the sockets, they were included in the plugs themselves. Hence the UK’s bigger plugs.
Why do different countries have different electrical outlet plugs?
Engineers developed the idea of a ground pin to make plugs safer in the 1920s. Many countries adopted these grounded plugs immediately, but they did not always make them the rule.So because different countries adopted innovations like these at different times, the plugs that they used changed throughout the years.
Are outlets in Europe different?
Europe’s electrical system is different from ours in two ways: the voltage of the current and the shape of the plug.A small adapter allows American-style plugs (two flat prongs) to fit into British or Irish outlets (which take three rectangular prongs) or continental European outlets (which take two round prongs).
Why do European plugs have no earth?
The British socket requires the earth pin to open the socket so they can have a plastic earth pin. In some case it is metal but it is not connected anywhere. Note how there are just two holes on the other end. That means the earth is not connected anywhere in the equipment.
Why do European plugs not have fuses?
Type G. The Europlug is physically not compatible with BS 1363 13 A sockets, used in e.g. the UK and Ireland. UK law requires a suitable fuse to be fitted in each plug to protect the appliance flexible cord; Europlugs do not contain such fuses.There is also a risk of damage to both the plug and socket.
Why are European plugs not polarized?
In many countries, including many in Europe, there is no polarization of the plugs and sockets, and some places there isn’t even an actual Neutral — both sides are Live. The manufacturer of your appliance or device has made it so. It also uses AC power, so polarity of the connection doesn’t matter for operation.
Why do European plugs have 2 pins?
What does 2-pole mean? 2-pole means that the device plug is not earthed and it normally has two pins that transmit electricity. Originally, all electrical devices were fitted with 2-pole plugs, which means that the devices were not earthed and that all mains sockets were constructed for 2-pole plugs.
Why does American and Europe have different voltage standards?
Europe and most other countries in the world use a voltage which is twice that of the US.Originally Europe was 120 V too, just like Japan and the US today, but it was deemed necessary to increase voltage to get more power with fewer losses and less voltage drop from the same copper wire diameter.
Does all of Europe use the same electrical plugs?
All of Europe operates on the same 2 round pronged outlets except for the UK and Ireland that operates on its own unique 3 flat rectangle pronged outlets. If you are travelling through the UK or Ireland (including London) you will need a UK and Ireland power point adapter.
Why do Australian outlets have switches?
Why Do Australian Power Points Have Switches? Australia has adopted switched sockets because they are safer. By flipping the switch to the ‘OFF’ position, you can prevent the current from flowing. This allows children to interact with sockets without suffering any dangerous shocks.
Which country has the best plugs?
Why Britain Has The Best Wall Sockets On Earth.
Why do British bathrooms not have sockets?
Why are there no plug sockets in British bathrooms? The reason that there are no plus sockets in bathrooms is simple – having an exposed plug socket can increase the risk of electric shock. Plugs in England generally use 240-volt power, twice the amount found in US plugs which have 120-volts.
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.
Are German and French plugs the same?
You can use your electric appliances in France, because the standard voltage (230 V) is the same as in Germany. So you don’t need a voltage converter in France, when living in Germany.
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.
Are EU plugs reversible?
Assuming that you are using a correct and supply authority-approved plug adapter, then it makes no difference at all which way round you insert the mains plug. These power supplies are double-insulated and are not earthed (grounded), so you won’t have to worry about any third pin either.
Why do UK sockets have 3 pins?
The 3-pin plugs are designed so that electricity can be supplied to electrical appliances safely. Each wire has its own specified color, as shown above and each pin must be correctly connected to the three wires in the electrical cable.
Does Europe have grounded outlets?
European plugs are grounded or ungrounded. Generally, the grounded plug is 3PIN, and the ungrounded plug is 2PIN. 2. Although there is only 2PIN, the other PIN is designed as a female socket, and the female socket is grounded.
How are European plugs grounded?
Continental Europe
Grounding is achieved through the grounding clips on the sides of the plug body. The CEE 7/7 plug also has a female receptacle, which permits it to be plugged into the French/Belgian sockets that have a male grounding pin.
Are EU plugs safe?
Using electrical products from other countries
Do not put yourselves or others at risk by using foreign electrical plugs in UK sockets. Using foreign appliances in UK sockets is dangerous if their plugs have not been converted for UK use, and it could result in a fire or electric shock.
