What is the resistance per 1,000 feet of 8 AWG copper uncoated, stranded conductors?

• A. 0.778 ohms
• B. 1.0 ohms
• C. 1.28 ohms
• D. 0.32 ohms

Answer: (A)

The resistance of electrical conductors is a key factor in determining how efficiently they can carry current over distance. For 8 AWG (American Wire Gauge) copper conductors, the standard resistance is approximately 0.628 ohms per 1,000 feet when considering solid wire. However, when dealing with stranded conductors, which typically have a slightly higher resistance due to the additional surface area and less effective current carrying capacity compared to solid conductors, the resistance increases. In the case of uncoated, stranded 8 AWG copper conductors, the resistance per 1,000 feet is typically accepted to be around 0.778 ohms. This figure accounts for the specifics of stranded wire construction while still representing a standard value used in electrical calculations and installations. It's important to know these resistance values, especially when planning electrical systems or adhering to electrical codes, as they impact overall performance and efficiency.
