For #2 AWG bonding conductor, what is the length range?

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

Answer: (D)

Bonding conductors create a single equipotential path among all metallic parts and the grounding system so there’s no dangerous voltage difference between components during normal operation or fault conditions. For a conductor of size #2 AWG, the recommended length range is 27 to 33 feet. This range is chosen because it provides enough length to reach multiple bonding points across typical equipment layouts without introducing unnecessary impedance or slack that can complicate routing. A shorter length often won’t span the required bonding points in a real installation, while a longer length could add unnecessary path length and potential inductance without improving the bond.

In short, 27-33 feet reflects a practical balance between sufficient reach to bond all needed points and keeping the path short enough to maintain a solid, low-impedance connection.
