For #1 AWG bonding conductor, what is the length range?

• A. 0-13 ft
• B. 14-20 ft
• C. 21-26 ft
• D. 34-41 ft

Answer: (D)

Bonding conductors are meant to create a continuous, low-impedance path for fault currents between bonding points. The conductor size determines its resistance per unit length, so guidelines specify a length range for a given gauge to keep the bond’s impedance within acceptable limits while still fitting typical site layouts. For a #1 AWG bonding conductor, the recommended range is 34 to 41 feet. This range provides enough length to span common bonding points without introducing excessive impedance that could weaken the bond during fault conditions. If the actual distance is outside this range, you’d adjust by using a larger conductor or adding additional bonding paths to maintain a low-impedance bond.
