What material is typically required for conductors used in vending machines as per the latest code?

The use of copper as the standard material for conductors in vending machines is primarily due to its excellent electrical conductivity and durability. Copper has a lower electrical resistance compared to other metals, which means it can carry more current with less energy loss in the form of heat. This property is crucial in vending machines, where efficiency and reliability are essential for their operation.

Additionally, copper's resistance to corrosion and its mechanical strength ensure that it remains reliable over time, even in environments where moisture or dust may be present. These characteristics make copper the preferred choice according to the latest electrical codes, which aim to ensure safety and efficiency in electrical installations.

While other materials like aluminum and steel have their applications in electrical work, they often do not offer the same balance of conductivity, corrosion resistance, and overall performance as copper. Plastic, while non-conductive, is utilized in insulating applications but is not suitable for conducting electricity.
