Three-pin plug, will it end?

Now that we are used to three-pin sockets, the government is studying the possibility of ending the three-pin sockets, is this the end of the three-pin sockets? If you haven’t seen it, you already have several reports about the end of the three-pin plugs on websites and newspapers. In this article from the World of Electrical explains what are the conditions for the mandatory three-pin plugs to end. Come on!

End of three-pin sockets

In 2011 it became mandatory that all devices manufactured in Brazil or imported from other countries came with the plug model for the three-pin sockets that we know today.

However, the standard that indicates the technical characteristics of the three-pin socket, which is NBR 14136, was published by  ABNT in July 1998, well before 2011. The image below shows a timeline on the history of the three-pin socket.

Timeline about the history of the 3-pin socket.

The history, the rules and ordinances of the three-pin socket, can be seen at the site INMETRO detailing all dates and documents about the making of three pins.

Can ABNT’s rule be canceled?

The government says it intends to end the three-pin plug, but maybe you’re wondering, can an ABNT standard be canceled like that?

Well yes, a standard can be canceled by ABNT itself, if ABNT understands that technically that standard no longer meets or else, the organized society and entities can ask ABNT to revise or cancel the standard, but this only happens if there is a technical basis.

What makes taking mandatory is not exactly the norm, but an INMETRO ordinance. The INMETRO ordinance may be revoked if the INMETRO board of directors understands that the ordinance is no longer viable based on technical data.

Can the government end the three-pin plug?

The government may appoint INMETRO’s board of directors and at the request or political pressure, the government may, in fact, pressure INMETRO to revoke the ordinance and remove the mandatory requirement for the three-pin plug. The standard will most likely not be canceled, as the reference standard and until then there are no technical reasons for such cancellation.

What happens if the standard is no longer mandatory?

With the end of the obligation, what will happen is that mainly imported equipment may come with any type of socket, that is, it will create the need to use several adapters again.

Re-create the need to use multiple adapters.

Brazilian manufacturers are unlikely to change the type of outlet again, which is already consolidated since the production lines are all adapted.

How is the security issue?

As much as it was a nuisance in the beginning when we think about security, these changes of plugs in 2011 provided a great advance, because these plugs of the standard of three pins are more secure!

ABINEE, which is the Brazilian Association of the Electrical and Electronics Industry, has already released a note opposing the project to release a standard of outlets aimed at the issue of security.

Final considerations

We professionals in the World of Electrical who install sockets every day, know that even with a standard and an obligation, there are excellent brands of sockets and other brands that have a lower quality of manufacture. Without the mandatory use of the standard, the quality of the sockets will certainly drop a lot.

We believe that removing an obligation that is already consolidated in the market will not bring great benefits to users, especially for everyone who followed the new guidelines and spent money adapting their homes and businesses for three-pin sockets.

Most likely these same users would have to spend more money on adapters for non-standard devices, which would bring insecurity into their electrical installation.
