Coming changes in electrical outlets and plugs
1Do you ever pay attention to the plug when buying
appliances? From now on, you will have to. Based
on INMETRO’s regulations, a new law already in effect makes
4 grounding mandatory. Therefore, three-prong plugs will
become commonplace, giving extra work to consumers as
early as this year.
7 The third prong provides a path to ground along
which the electric current travels. Electrical outlets will also
have three-wire receptacles that accommodate electrical
10 cords with three-prong plugs. Most major appliances, such as
stoves, refrigerators, and computers, have three-prong plugs,
meaning that they are grounded. Most older homes do not
13 have three-wire receptacles. If yours does not, you should
have an electrician rewire the home to accommodate the
three-prong plugs. Although three-prong adapters (called
16 cheater plugs) can be purchased, they are not recommended
for permanent use. Also remember never to clip the third
prong off a plug to make it fit a two-hole outlet.
19 The idea behind grounding is to protect the people
who use metal encased appliances from electric shock.
The casing is connected directly to the ground prong. Thus,
22 INMETRO’s concern is solely with safety. People touching
a refrigerator, for instance, will not get any potentially fatal
shocks.
25 Changes will have been introduced gradually by
2009, so as not to cause a profound impact on the population.
Electrical outlets will already be available with the third
28 receptacle. However, this will be useless unless it is
grounded. By law, new constructions must have grounding.
As of 2010, all appliances which need the third
prong will already include it. Not all outlets need to be
31 modified. Only those which will accommodate three-prong
plugs such as those for washing machines. Old appliances
34 with round pins will continue to operate normally.
With this initiative, INMETRO expects to solve
existing problems with electrical outlets. At present, there are
37 around twelve different types on the market. It is not
uncommon to try to push the plug into an outlet without
being completely successful. If it is not totally pushed in, the
40 part that is left out becomes a great risk of accidents. With
the new standard plug such risk will be eliminated.
Appliances which will continue to operate with two-
43 prong plugs are televisions, DVDs, video games and
blenders. Those requiring the third prong are microwave
ovens, air conditioners, washing machines, and freezers.

As of 2010, all appliances which need the third
prong will already include it. Not all outlets need to be
31 modified. Only those which will accommodate three-prong
plugs such as those for washing machines. Old appliances
34 with round pins will continue to operate normally.
With this initiative, INMETRO expects to solve
existing problems with electrical outlets. At present, there are
37 around twelve different types on the market. It is not
uncommon to try to push the plug into an outlet without
being completely successful. If it is not totally pushed in, the
40 part that is left out becomes a great risk of accidents. With
the new standard plug such risk will be eliminated.
Appliances which will continue to operate with two-
43 prong plugs are televisions, DVDs, video games and
blenders. Those requiring the third prong are microwave
ovens, air conditioners, washing machines, and freezers.

Coming changes in electrical outlets and plugs
1 Do you ever pay attention to the plug when buying
appliances? From now on, you will have to. Based
on INMETRO’s regulations, a new law already in effect makes
4 grounding mandatory. Therefore, three-prong plugs will
become commonplace, giving extra work to consumers as
early as this year.
7 The third prong provides a path to ground along
which the electric current travels. Electrical outlets will also
have three-wire receptacles that accommodate electrical\quad
10 cords with three-prong plugs. Most major appliances, such as
stoves, refrigerators, and computers, have three-prong plugs,
meaning that they are grounded. Most older homes do not
13 have three-wire receptacles. If yours does not, you should
have an electrician rewire the home to accommodate the
three-prong plugs. Although three-prong adapters (called
16 cheater plugs) can be purchased, they are not recommended
for permanent use. Also remember never to clip the third
prong off a plug to make it fit a two-hole outlet.
19 The idea behind grounding is to protect the people
who use metal encased appliances from electric shock.
The casing is connected directly to the ground prong. Thus,
22 INMETRO’s concern is solely with safety. People touching
a refrigerator, for instance, will not get any potentially fatal
shocks.
25 Changes will have been introduced gradually by
2009, so as not to cause a profound impact on the population.
Electrical outlets will already be available with the third
28 receptacle. However, this will be useless unless it is
grounded. By law, new constructions must have grounding.
