Which length range applies to a #2 AWG bonding conductor?

• A. 0-13 ft
• B. 14-20 ft
• C. 21-26 ft
• D. 27-33 ft

Answer: (D)

Bonding conductors must provide a direct, low-impedance path between bonded metal parts, and the allowable jumper length is specified by the conductor size. For a #2 AWG bonding conductor, the standard assigns a longer permissible jumper length because this gauge has enough cross-sectional area to carry fault current efficiently over a longer run without unacceptable impedance. That’s why the applicable length range is the 27-33 ft band. The shorter ranges correspond to smaller gauges and don’t apply to #2 AWG, since they reflect different sizing guidelines for bonding jumpers. This approach keeps the bond effective across typical site layouts while avoiding excessive resistance from unnecessarily long runs.
