What is the cross-sectional area of 8 AWG THW conductor?

The cross-sectional area of an 8 AWG THW (Thermoplastic Heat and Water resistant) conductor is indeed 0.0437 square inches. This value is derived from established standards for wire gauges, where AWG (American Wire Gauge) sizes have specific cross-sectional areas. For 8 AWG wire, the cross-sectional area is typically known to be around 0.628 mm², which converts to approximately 0.0437 in.².

This size allows the conductor to carry the appropriate current safely while minimizing the amount of heat generated due to electrical resistance. In practical applications, understanding the cross-sectional area is essential for ensuring that the wire can handle the expected load without overheating or losing efficiency.
