Verified 2026-10-28 Confidence: High

Appendix C to 29 CFR 1910.269 explains that a higher fault current generally brings a shorter clearing time for the same type of fault, so the grounding method maximizes the fault current through a low impedance connection to the lowest impedance ground available at the worksite, which is a grounded system neutral conductor where one is present. The explanation sits in section III.D.2.i of the appendix.

    Read the reference passage
    "Generally, the higher the fault current, the shorter the clearing times for the same type of fault. Therefore, to ensure the fastest available clearing time, the grounding method must maximize the fault current with a low impedance connection to ground. The employer accomplishes this objective by grounding the circuit conductors to the best ground available at the worksite. Thus, the employer must ground to a grounded system neutral conductor, if one is present."
