What type of wiring is commonly used in modern homes today?

In modern homes, copper wiring is the standard choice due to its excellent conductivity, durability, and flexibility. Copper wires allow for efficient electrical flow with minimal energy loss, making them ideal for residential electrical systems. They are also less likely to overheat compared to other materials when conducting electricity, which enhances safety.

Additionally, copper has a long lifespan and is resistant to corrosion when properly insulated, contributing to the longevity of electrical systems. While aluminum is sometimes used for larger power distribution due to its lightweight properties, it has lower conductivity and requires larger wire sizes to carry the same load safely. Plastic-insulated wiring is often an insulation type rather than a wire type, and fiberglass is not commonly used for electrical wiring in residential settings. Thus, copper remains the preferred and standard material for wiring in modern homes.
