How would vicinity normally be defined? Would some sort of divider be required or just so that clothes or ignitable materials shouldn't be within a certain distance?
The idea is to prevent fires. A 240 volt panel with as little as a 10kva fault can throw molten metal several feet. Should this molten metal be able to hit something flammable then I would say that the flammable would be in the vicinity.
Electrical firesThe most inclusive and direct interpretation of “electrical fire” is a fire involving some type of electrical failure or malfunction. Any equipment powered by electricity can have such a failure.
In 2011, an estimated 47,700 home structure fires reported to U.S. fire departments involved some type of electrical failure or malfunction as a factor contributing to ignition. These fires resulted in 418 civilian deaths, 1,570 civilian injuries, and $1.4 billion in direct property damage. In 2007-2011, home electrical fires represented 13% of total home structure fires, 18% of associated civilian deaths, 11% of associated civilian injuries, and 20% of associated direct property damage.
I don’t suppose that the above paragraph means much unless you are included in that 47,700. If you was one of the 418 you wouldn’t be able to read this.
