The smallest permitted size system bonding jumper for Panel LK is AWG ___.

The smallest permitted size system bonding jumper for Panel LK is AWG ___.

• A. 2
• B. 3/0
• C. 6
• D. 2/0

Answer: (D)

Sizing the system bonding jumper is about ensuring the neutral-to-ground bond in service equipment can carry fault current safely and meet the panel’s listing requirements. For Panel LK, the minimum size allowed for that bonding jumper is AWG 2/0 copper. That means any conductor smaller than 2/0 (such as 2 or 6) isn’t permitted, while a larger size like 3/0 would also be acceptable but is not the smallest. Using 2/0 ensures the bond can handle potential fault current without overheating, in line with the panel’s rating and NEC guidance for service equipment bonding.
