The term "26-gauge" refers to a specific thickness of metal or wire, commonly used in various applications, including construction and manufacturing. In the context of sheet metal, a 26-gauge sheet is approximately 0.0187 inches thick. This measurement is part of a standardized gauge system, where a lower gauge number indicates a thicker material. In the realm of electrical wiring, 26-gauge wire is often used for low-power applications, such as in telecommunications and electronics. It is lightweight and flexible, making it suitable for intricate designs and connections. However, it may not be ideal for high-current applications due to its limited capacity.
