Which wiring method is commonly used in residential construction?

Romex wiring, also known as non-metallic sheathed cable, is the most widely used wiring method in residential construction. This popularity stems from several key advantages.

Firstly, Romex is relatively easy to install. It consists of insulated conductors enclosed in a flexible sheath, which simplifies the process of running wires through walls, ceilings, and floors. Electricians can maneuver it around corners and through tight spaces more easily than other methods.

Secondly, this wiring method is cost-effective. The materials used in Romex are relatively inexpensive compared to armored cable or other methods, making it an economical choice for residential projects.

Additionally, Romex provides adequate insulation and protection for the conductors, ensuring that they are safe from moisture and physical damage, which is crucial in a residential environment where wires may be subject to varying conditions.

While other wiring methods such as knob and tube or armored cable are used, they tend to be less common in new residential construction. Knob and tube wiring is outdated and often found in older homes, while armored cable is more frequently used in commercial or industrial settings due to its robustness. Wire duct systems are generally used in larger commercial buildings for organizing multiple cables and wires rather than in typical residential applications.
