Wire specifications refer to the detailed characteristics and standards that define the performance and suitability of electrical wires. These specifications include factors such as wire gauge, material type, insulation type, and temperature rating. Common materials used in wires include copper and aluminum, each offering different conductivity and flexibility. Understanding wire specifications is crucial for ensuring safety and efficiency in electrical installations. For example, the American Wire Gauge (AWG) system helps determine the wire's thickness, affecting its current-carrying capacity. Proper selection based on these specifications helps prevent overheating and electrical failures in various applications.
