O Brasil adotou um novo padrão de tomadas, com três pinos, prevendo uma maior segurança aos usuários. As características desse novo padrão são o recuo da entrada da tomada, que é mais profundo, dificultando o acesso de crianças aos orifícios, e a implantação de um pino terra, até então encontrado só em máquinas de lavar e outros eletrodomésticos.
O pino terra é o que faz a ligação do aparelho com o sistema de aterramento da rede elétrica, protegendo o usuário de pequenos choques que podem eventualmente ocorrer. Também protege produtos mais delicados, como computadores, TVs, impressoras, decodificadores e muitos outros.
Segundo o professor do curso de Engenharia Elétrica da FURB, Sérgio Henrique Cabral, além da padronização das tomadas e pinos, os adaptadores também terão que seguir normas pré-estabelecidas. “Os adaptadores hoje não podem ser considerados seguros. Eles perdem o efeito de segurança e descaracterizam o objetivo da medida”, comenta. 
Mas, além de trocar as tomadas, o novo padrão torna necessário trocar, também, toda a fiação elétrica. Segundo o professor “não adianta só trocar a capa da tomada, pois é preciso mudar a fiação para a implantação do fio terra, o que acaba tornado a adaptação mais cara”.
E não é de hoje que o país vem tentado implantar essa medida de padronização. Cabral comenta que já são mais de 14 anos desde que a medida vem sendo falada no Brasil, e só agora está sendo efetivamente colocada em prática. “Pela segurança que proporciona, ele vale à pena”, finaliza o professor.
