In one- or two-family dwellings, what is the maximum length for the primary protector bonding conductor or grounding electrode conductor?

The maximum length for the primary protector bonding conductor or grounding electrode conductor in one- or two-family dwellings is established to ensure effective grounding and electrical safety. The code allows a maximum length of 20 feet for these conductors to maintain proper system performance and to minimize the risk of voltage drop and electrical interference.

Using a conductor longer than this specified length can potentially lead to increased resistance, resulting in inadequate grounding for the electrical system, which is crucial for both effective surge protection and safety. Therefore, adherence to this length is necessary to ensure that the system functions as intended and reduces hazards associated with electrical faults.
