(pronounced PA-nehl bahks)

Also known simply as a “panel” or a “breaker box,” a panel box truly is a box. Made out of metal and attached to or inset into a wall located in a garage, mechanical room, or otherwise out-of-the-way location, the box contains circuit breakers and is the central panel bringing power into a home or building. You will sometimes here older people use the term “fusebox” to refer to a panel.
