Which of the following types of cable is NOT typically used for residential wiring?

Fiber optic cable is not typically used for residential wiring due to its primary purpose and the nature of its construction. While it is excellent for high-speed data transmission and is commonly found in telecommunications and internet infrastructure, it does not serve traditional electrical wiring functions such as providing power to outlets, switches, or fixtures within a home.

In contrast, NM cable (non-metallic sheathed cable) is widely used in residential wiring for circuits, offering a safe and economical way to supply electrical power. Armored cable provides additional protection against physical damage and is sometimes utilized in residential applications, particularly in exposed areas. THHN cable is used in building wiring and is suitable for conductors that must be able to withstand higher temperatures and require protection from heat and moisture, making it suitable for various applications, including residential ones.

Given these distinctions, fiber optic cable stands out as being unrelated to the more conventional electrical wiring needs found in homes.
