The Brazilian standard for 3-pin sockets was implemented in the country as it is a model that offers more security. Another justification is regarding standardization, which aims to prevent overloads in electrical installations.
Do you know who invented the 3-pin plug? Is it true that this pattern of taking is exclusive to Brazil? Is the 3-pin plug also used in the USA? What is the socket pattern used in Europe? In this article we will answer these questions and explain why Brazil adopted this pattern of outlets.
The Brazilian Association of Technical Standards was responsible for formulating the standard with this plug model. This standard was in public consultation for several months until being finalized in 1998. In 2000, Inmetro informed through a published ordinance that the market had a period of 10 days to adopt this standardization. Therefore, all products launched should have the 3-pin plug standard.
Why did the outlets standardize?
Brazil had more than ten different types of plugs and sockets. As a result, the use of adapters was frequent and in many cases, there were more devices connected to adapters than to their correct outlets. All of these differences caused overloads and waste in electrical installations.
Is a 3-pin plug safer?
In addition to standardizing, the issue of safety has also been extensively analyzed and according to experts, people who handle this new outlet are less likely to suffer accidents. After the plug is completely connected, it offers total isolation.
How does this isolation happen? The third pin is the great differentiator of this socket, it was created to receive the pin of the ground wire, that is, offering much more security to the users, in case of any leakage of current to the device or to a person who accidentally touches it, the person will have the consequences of the shock minimized.
It is very important to note that this ground pin will only be useful in houses designed with a grounding system, otherwise it will be just one more pin in the socket that does not interfere with anything.
Does only Brazil have 3-pin sockets?
The answer is no! Countries like the United States, Canada, England, Ireland and Saudi Arabia are some of those that also use the standard 3-pin plug. This difference in standard is common since each nation has its own electrical standards. Therefore, it is natural to find out that you will only need to purchase an adapter when you arrive in the country.
It is very important to research the plug and voltage standard, popularly called the voltage, of the country you intend to go to. The voltage range in Australia and New Zealand, for example, is 240 volts. In Japan they use 100 volts. If the person does not pay attention to the voltage of the installation, he may burn his electrical device.
There are several devices that have versatility in this operating voltage, such as notebook chargers. But it is essential that you research the voltage for your device before you even travel, this is the best way to avoid headaches and damage.
Following our article, we will talk about some countries and what are the outlet patterns used there. Observe the small details well so as not to get confused, since there are very similar models, but with different specificities.
- North, Central America and Japan – They use the plug consisting of two flat, parallel pins. In some parts of the United States, one of the pins is wider.
- Europe – With the exception of the United Kingdom, all other countries use the plug with two rounded, parallel pins. This was the plug used in Brazil before standardization with the 3-pin.
Even in the countries mentioned, it is important to note that there are some areas in which the pattern may be different, but they are minorities. Several countries have made adaptations to this 2-pin plug in order to make it safer.
In Germany, Austria, Bulgaria, Croatia, Spain, Estonia, Finland, Greece, Holland, Hungary, Iceland, Portugal, Norway, Russia, Sweden, for example, they used two of its ends with a small clip that serves as a ground wire. The good news is that the devices with a standard 2-pin plug without this extra clip, work normally in these countries, but it will be easily noticed a greater difficulty in connecting them to the sockets.
It became very clear that there are different patterns around the world and that tensions also vary widely. Research well and don’t be caught off guard on your trip. Some research carried out indicated that there was a reduction in overload after the standardization of the shots in Brazil, that is, despite all the headache, this standardization did bring benefits to its users.
