America’s residential electrical symbols and their origins
As Americans prepare for Christmas, a new residential electrical symbol has popped up, with some experts saying the design originated in a garage in Kansas City.
In a tweet from the official account of the National Association of Home Builders, the group announced that the symbol, which is the same as the ones used by the American Residential Insurers Association (ARIA), was designed by John Bostwick, who worked at a local hardware store.
The sign, which also appears on some other residential metalgarages in the United States, reads: “Do not touch any electrical equipment, including electricity.”
The association said in a statement that it believes the design, which was first unveiled on October 21, has been around for decades.
The association also said that the name “residential metalgarage” was coined in the 1980s by a local metalworker.
It was the name that stuck.
“We started out with that because of our proximity to metalworkers, because that’s what metalworkers are used to,” Mark Tumlinson, the president of the Association of Metalworkers in America, told Vice News.
“We knew that it was a good name.
And then people started talking about it in the last year or two.”
While the metalworker-inspired design was first used in the U.S. in the early 1990s, the metalwork has continued to be used throughout the world, including in Japan.
In 2014, the Japanese government launched an initiative called the Metalwork Challenge, which aimed to encourage metalworkers to take part in the project.
“The goal of the Metalworks Challenge is to encourage Japanese metalworkers who are skilled in making steel to become part of the initiative,” Japan’s Metalwork Promotion Agency said in the announcement.
“They can receive training in the techniques of metalworking and then get a job with the company they’ve chosen.”
The metalworker symbol was inspired by the Japanese metalworker group known as “Takashi.”
The group was founded in 1974 and includes about 30,000 members.
