Correct answer to question 5063
- C: Table 250.102(C)(1) based on the ungrounded service conductors

Supply-side bonding jumpers are sized from Table 250.102(C)(1) using the largest ungrounded conductors within the raceway or enclosure. No OCPD protects these conductors, so Table 250.122 does not apply. See 250.102(C).
