The physical size of metallic sheathed cable with a 2/3 American Wire Gauge (AWG) designation varies depending on the manufacturer and the specific construction of the cable. Factors influencing the overall dimension include the thickness of the metal sheath, the type and thickness of the insulation surrounding the conductors, and the stranding of the conductors themselves. As a result, providing a single, definitive measurement is impossible. Referencing the manufacturer’s specifications for the particular cable in question is crucial for accurate sizing.
Understanding the outer dimension of this type of cable is vital for various applications. It affects conduit fill calculations, ensuring compliance with electrical codes and preventing overheating. It also influences the selection of appropriate fittings, connectors, and cable clamps, guaranteeing secure and reliable electrical connections. Historically, armored cable has been utilized to provide robust physical protection to conductors, minimizing the risk of damage from impact, abrasion, and environmental factors. This makes it a preferred choice in environments where wiring is exposed or subjected to harsh conditions.
