Identify a common application for raceways in residential buildings.

Raceways are essential components in residential buildings primarily used to organize and protect electrical wiring. The answer focusing on running electrical wiring for lighting fixtures is particularly relevant because lighting is a fundamental requirement in any residential space. Raceways provide a safe and efficient pathway for electrical conductors that connect to various lighting fixtures throughout the home.

When considering residential applications, running electrical wiring for lighting not only ensures safety by minimizing exposure to physical damage but also helps maintain an organized appearance. Properly installed raceways facilitate the installation process for electricians and allow for future modifications or expansions without significant disruption to the structure of the home.

While the other applications listed are indeed possible uses for raceways, they do not represent the most common application in typical residential settings. Lighting fixtures are ubiquitous and are integrated into nearly every room, making raceways for this purpose particularly prevalent.
